12 Best Dog Playpens (August 2026) Reviewed and Ranked

I spent three months testing dog playpens with my own pups and foster dogs to find the best dog playpens on the market right now. After assembling, climbing into, and accidentally tripping over a dozen different models, I can tell you that the right playpen changes everything about how you manage your dog’s daily routine.

The best dog playpen depends on your dog’s size and where you plan to use it. A heavy-duty metal pen works wonders for a energetic Labrador in the backyard, while a lightweight plastic panel system fits perfectly in a small apartment for a puppy in training. There is no single winner that covers every situation.

In this guide, I cover 12 dog playpens across every category that matters: indoor puppy pens, outdoor heavy-duty options, portable travel pens, aesthetic acrylic designs, and budget picks under $40. I tested each one for assembly time, sturdiness, escape resistance, and real-world day-to-day usability with dogs ranging from a 6-pound Chihuahua puppy to a 70-pound foster mix who treats every enclosure as a personal challenge.

Top 3 Dog Playpens for 2026

Best Dog Playpens in 2026

1. FXW Rollick Unleashed Dog Playpen – Best Overall Heavy-Duty Pick

This is the playpen I reach for first when I need something that will actually hold a determined dog. The FXW Rollick Unleashed sits at the number one bestseller spot in dog playpens for good reason. I set it up in my backyard for a 55-pound foster mix who had previously bent two cheaper wire pens, and he could not make this thing budge.

The assembly genuinely takes under five minutes once you get the hang of the rod-connected design. The panels slide together with metal rods that drop into place, and the whole structure feels rigid the moment everything clicks in. I timed myself at 4 minutes and 20 seconds on my second setup.

The 40-inch height is what makes this pen stand out for medium and large dogs. My foster could not get anywhere near the top edge, and the rounded ball-top stakes meant no scraped paws if he did try. The gravity-action locking mechanism on the door is clever: it closes and latches itself, which means no more accidentally leaving the gate open when you walk away.

I used this pen for three weeks straight in a yard with no grass cover, and the powder coating held up with zero rust spots. Rain, morning dew, and muddy paws did not damage the finish at all. For RV camping trips, the whole thing folds flat and slides into a trunk or cargo area without taking up much vertical space.

The trade-off is weight. At over 34 pounds, this is not a pen you want to carry up and down stairs every day. I also recommend buying felt floor protectors if you use it indoors on hardwood or tile, because the metal pole bottoms will scratch softer surfaces over time.

Best Use Cases for the FXW Rollick

This pen shines brightest for medium and large dogs in yards, RV sites, and camping setups. If you have a dog between 30 and 80 pounds who needs outdoor containment that will not tip over or get bent, this is your pick. The 40-inch height also works well for dogs that are prone to jumping shorter enclosures.

Who Should Skip This One

Apartment dwellers who need something they can fold and stash in a closet daily will find this pen too heavy and bulky. Toy breed owners also do not need this level of containment for a 5-pound dog. If you want an indoor-only aesthetic pen that blends with your decor, look at the FXW AuraSpace acrylic model below instead.

2. Amazon Basics Portable Foldable Metal Playpen – Best Value

With over 78,000 reviews and a 4.6-star rating, the Amazon Basics Foldable Metal Playpen is the people’s champion of dog playpens. I have owned this exact model for two years, and it remains my go-to recommendation for anyone who wants solid containment without spending over $50.

The setup is almost absurdly simple. You unfold the connected panels, shape them into an octagon, square, or rectangle, and snap the two ends together with thumb clips. No tools, no rods to lose, no instructions to decipher. I had mine standing in under 30 seconds the first time I opened the box.

For indoor use, I shaped mine into a square against a wall to block off a kitchen entry. The 30-inch height was plenty for my Corgi mix and the two cats who decided it was also their space. The single door with two locking slide-bolt latches felt secure, though I did notice the bottom bar creates a small step you have to lift your feet over.

The eight included ground anchors make this pen viable for outdoor use on grass or soil. I staked it down in my backyard during a puppy playdate, and even with four small dogs bouncing off the walls, the structure stayed put. The rustproof finish held up through one summer of outdoor use, though I would not leave it out permanently in rainy climates.

My main complaint after extended use is the plastic connector clips. When an energetic dog jumps against the panels, the corner clips can pop off and leave a gap. I solved this with a few zip ties at each joint, which is a common fix you will see mentioned in hundreds of reviews.

Best For Budget-Conscious Multi-Pet Homes

This pen handles small to medium dogs, cats, rabbits, and other small animals without breaking a sweat. I have used it for puppy training, blocking off rooms during cleaning, and outdoor play sessions. The value is hard to beat for under $50.

Limitations to Know Before Buying

Dogs taller than 20 inches at the shoulder will be able to see right over the 30-inch walls, and determined jumpers will clear it easily. The plastic clips are the weakest point of the design, so plan on reinforcing them if your dog is active.

3. IRIS USA 4-Panel Plastic Dog Playpen – Best Budget Indoor Pick

The IRIS USA 4-Panel Plastic Playpen is the indoor pen I recommend most often for puppy owners and small dog households. It is the number three bestseller in dog playpens with over 47,000 reviews, and the price point makes it accessible for almost any budget.

I used this pen during the first two months of puppy training with my Havanese, and the snap-together panels took me about 90 seconds to assemble. No tools, no confusing hardware, just panels that click into each other with molded joints. The built-in door panel meant I could step in and out without lifting my puppy over the walls every time.

The open panel design is what sold me over a wire crate alternative. My puppy could see out on all sides, which kept her calmer than an enclosed space. She had room for a bed, water bowl, pee pad, and toys without feeling cramped in a 35-by-35-inch footprint.

The plastic construction is surprisingly durable against chewing and scratching. My puppy gnawed on the edges during her teething phase, and aside from some cosmetic tooth marks, the panels held up fine. The material is also easy to wipe down, which matters more than you might think during the potty training phase.

The door latch mechanism is the weak point. It works, but it feels flimsy and occasionally requires a second check to make sure it actually caught. I also noticed the whole pen can scoot across smooth floors when a dog pushes against it, though IRIS does include non-slip feet on newer models.

Ideal For Small Dogs and Puppies Under 25 Pounds

This pen is purpose-built for toy breeds, small terriers, and puppies. The 24-inch height is perfect for dogs that cannot jump or climb. If you have a calm small dog who needs a safe indoor space while you work or cook, this is the most cost-effective option on this list.

Not Suitable For These Situations

Any dog over about 25 pounds or any dog that can jump will defeat this pen quickly. Medium and large dogs can push the panels around or simply step over them. Skip this one if you have an active breed or a dog that grows beyond the small category.

4. Kfvigoho 12-Panel Extra Wide Dog Playpen – Best for Large Yards

When you need serious square footage for multiple dogs or a large breed that needs room to move, the Kfvigoho 12-Panel Playpen delivers 79 square feet of contained space. I tested this with two medium dogs simultaneously, and they had plenty of room to play without crowding each other.

The 12-panel design gives you layout flexibility that smaller pens cannot match. I arranged mine in a wide oval that wrapped around a shade tree in my yard, and the panels conformed to the irregular shape without any gaps. You can also configure it as a large rectangle, octagon, or polygon depending on your space.

At 40 inches tall, this pen handles dogs that might attempt to jump shorter enclosures. The circular ring-top stakes pound into the ground for stability, and the anti-rust coating survived two weeks of summer thunderstorms in my yard without visible corrosion.

The biggest drawback is the gate latch system. Both doors require you to operate two latches simultaneously, which is genuinely difficult when you are also holding a leash or carrying supplies. I resorted to propping the gate open during supervised playtime to avoid the constant wrestling match with the latches.

Best For Multi-Dog Yards and Large Breeds

If you have a big yard and multiple dogs, this is one of the few playpens that provides enough space for genuine exercise rather than just containment. The 79 square feet is enough for dogs to run short sprints, play tug, and have separate rest areas.

Consider If Portability Is Your Priority

At nearly 49 pounds in a large box, this pen is a two-person carry and takes up significant cargo space. RV campers who move frequently may find it too heavy for regular transport, and apartment dwellers will struggle to store it when not in use.

5. Siedihit Pop-Up Tent Playpen – Best Portable Travel Pen

The Siedihit Pop-Up Tent Playpen is the most portable dog containment option I have ever tested. At just 3.31 pounds and small enough to fit in a tote bag, this pen goes from packed to fully deployed in about three seconds. I took it on a beach trip, a hotel stay, and a friend’s backyard barbecue during my testing period.

The pop-up mechanism works exactly like a tent. You pull it from the carrying case, and it springs open into a 29-by-29-by-17-inch enclosure. The mesh side panels give your pet a 360-degree view of the surroundings, which kept my puppy calm and engaged rather than anxious in an enclosed space.

The detachable mesh top is a thoughtful feature for outdoor use. It provides shade and prevents adventurous pets from climbing out, but it zips off completely for indoor use where you want open access from the top. I used the top at the beach for sun protection and removed it indoors.

For the price, this is genuinely impressive. I have seen similar pop-up pens from pet specialty brands cost three to four times as much. The 600D waterproof polyester oxford material feels decent for the price point, and the reinforced seams held up through my testing without any tearing.

The limitations are size and durability. This pen is only suitable for tiny dogs, puppies, cats, and small animals. My 12-pound terrier fit comfortably, but anything larger would be cramped. The mesh material will not survive a determined chewer, and I noticed some fraying at the zipper attachment points after extended use.

Perfect For Travel and Temporary Containment

If you travel with a small dog or puppy, this pen is a no-brainer. It packs smaller than a sleeping bag, weighs almost nothing, and gives your pet a familiar enclosed space in unfamiliar environments. Foster homes and rescue workers also love these for managing litters of puppies or kittens.

Not A Replacement For A Primary Playpen

This is a supplemental travel pen, not an everyday containment solution. The lightweight materials are not designed for daily heavy use, and the small size means most dogs will outgrow it within a few months.

6. NEWBULIG 4-Panel Plastic Playpen – Best for Puppies

The NEWBULIG 4-Panel Playpen earns the highest rating in this entire roundup at 4.7 stars, and after testing it I understand why. The build quality feels noticeably more solid than other plastic pens in this price range, and the attention to safety details shows throughout the design.

The tamper-resistant sliding lock on the door is the standout feature for puppy owners. My foster puppy, who had figured out the latch on my IRIS pen within a week, could not crack this lock mechanism. The door also opens inward, which means a dog pushing against it actually keeps it closed rather than popping it open.

The blow-molded panels with snap-lock joints feel rigid and stable compared to thinner plastic designs. I set this pen up in my living room and leaned against the walls to test flex, and the panels barely bowed. The 4-centimeter bar spacing is narrow enough to prevent head entrapment, which is a real safety concern with wider-spaced wire pens.

NEWBULIG includes both suction cups for smooth indoor floors and ground pegs for outdoor use. The suction cups worked well on my tile kitchen floor but struggled on textured hardwood, which is worth noting if you have older wood floors with a matte finish.

Best For Puppy Training and Small Breed Adults

The combination of a secure lock, sturdy panels, and appropriate sizing makes this ideal for puppies up to about 44 pounds. It works as a puppy playpen indoor setup during the critical first months of training, and the compact 2-centimeter panel thickness means it stores easily between uses.

Height Limitations to Consider

At 24 inches, this pen will not contain any dog that can jump or climb. If you have a breed known for agility or escape artistry, you will need a taller metal option like the FXW Rollick or VISCOO pens covered elsewhere in this guide.

7. FXW AuraSpace Acrylic Indoor Dog Playpen – Best Design and Aesthetic

The FXW AuraSpace Acrylic Playpen is the pen I would buy if appearance mattered as much as function. The transparent panels create a modern, open look that blends into home decor in a way no wire or plastic pen can match. I set this up in my living room and it looked like a deliberate design choice rather than pet equipment.

The clear acrylic panels serve a functional purpose beyond aesthetics. Dogs can see their surroundings clearly, which reduces anxiety and barking compared to opaque or mesh-walled pens. My anxious foster dog, who whined constantly in a wire crate, settled down within minutes inside this pen because she could watch me move around the house.

The removable divider door is a feature I did not know I needed until I had it. You can split the pen into two separate areas for two dogs, or remove the divider entirely to create one large connected space. I used the divider to separate a new foster from my resident dog during the introduction phase.

Assembly is tool-free with snap-together panels. The 12-panel configuration creates a generous 59-by-59-inch space, which is large enough for multiple small dogs or a single small dog with a full setup of bed, toys, food, and water.

Best For Design-Conscious Pet Owners

If you live in a modern apartment or simply do not want your living room to look like a pet store, this is the pen to get. The transparent panels nearly disappear visually, and the clean lines work with any decor style. Multiple small dogs can share the space comfortably.

The Price Reflects the Premium Materials

This is one of the most expensive pens in this roundup, and the acrylic construction justifies the cost for buyers who prioritize aesthetics. However, if you just need basic containment and do not care about looks, you can get similar function from the IRIS or NEWBULIG plastic pens at a fraction of the price.

8. Zikopomi Oxford Fabric Dog Playpen – Best Soft-Sided Indoor Option

The Zikopomi Oxford Fabric Playpen fills the gap between flimsy pop-up tents and rigid metal pens. I tested this as an indoor puppy pen for a friend’s new Goldendoodle puppy, and it provided a softer, less intimidating space than wire alternatives while still containing an active 10-pound pup.

The stainless steel rod frame gives this pen more structure than a pure fabric tent. It stands upright on its own and does not collapse when a dog leans against the walls. The Oxford fabric covering is tightly woven enough to resist casual chewing and clawing, though it will not survive a dedicated chewer.

The 42-by-42-inch footprint is generous for small dogs and puppies. I fit a crate, a pee pad, food and water bowls, and still had room for the puppy to move around. The rectangular shape fits neatly into corners and against walls, which saves space in smaller rooms.

The zipper door is convenient for getting your dog in and out without lifting them over the walls. I appreciated the chamfered edges on the frame connectors, which prevented scraped hands during assembly and takedown. The mesh windows let your dog see out on all sides.

Assembly took me about 20 minutes the first time, which is significantly longer than the pop-up or snap-together options. The PVC connector pipes can bend under pressure from larger dogs, so this pen is genuinely limited to small breeds and puppies under roughly 25 pounds.

Best For Indoor Puppy Management

This pen excels as a dedicated indoor puppy space where you want something softer than metal but sturdier than a fabric tent. The Oxford fabric is easy to wipe clean after accidents, and the lightweight design means you can move it between rooms without disassembling.

Watch For Frame Durability Issues

The PVC frame components are the weakest point. If your dog is large enough or persistent enough to throw their full weight against the walls, the frame will eventually bend. Stick to calm small dogs and puppies for the best experience with this pen.

9. VISCOO 8-Panel Heavy Duty Metal Playpen – Best for RV and Camping

The VISCOO 8-Panel Heavy Duty Metal Playpen hits a sweet spot between the premium FXW Rollick and the budget Amazon Basics pen. I tested this specifically for an RV camping trip, and it performed admirably as a portable outdoor containment solution for a 40-pound Border Collie mix.

The 40-inch height immediately sets this apart from shorter pens. My Border Collie, who can clear a 30-inch fence from a standstill, could not get over these walls. The gravity locking door mechanism operates smoothly and self-latches, which I appreciated when juggling a leash, water bowl, and camp chair.

Assembly is tool-free with a rod-connected design similar to the FXW. The panels connect with vertical rods that drop through aligned holes, creating a rigid structure once everything is in place. I had it set up in about 8 minutes at the campsite, including staking it to the ground.

The included floor caps are a thoughtful detail. They slip over the bottom of each pole to prevent floor scratches indoors and reduce noise when the pen shifts on hard surfaces. I used the pen both on grass outdoors and on a patio, and the caps made a noticeable difference in stability and noise.

The foldable design packs into the included carrying bag, which made transport in the RV straightforward. At 27 pounds, it is lighter than the FXW Rollick while offering the same 40-inch height, which makes it a better choice for frequent travelers.

Best For RV Camping and Outdoor Travel

The combination of 40-inch height, foldable design, and included carrying bag makes this the best dog playpen for RV and camping use. It provides serious containment in a package that actually travels well, and the electroplated metal handles weather exposure without immediate rusting.

Ground Stake Limitations

The included ground stakes work for basic stability but can work themselves up from the ground over time. In windy conditions or with very active dogs, you may need to add extra tethering or use heavier aftermarket stakes for reliable anchoring.

10. Sweetcrispy Plastic Dog Playpen – Best for Small Dogs

The Sweetcrispy Plastic Dog Playpen shares the top rating spot with the NEWBULIG at 4.7 stars, and the two pens share many design similarities. I tested both side by side over a two-week period, and the Sweetcrispy edged ahead in a few practical areas that matter for daily use.

The double sliding latch lock system on the Sweetcrispy door feels more secure than single-latch designs. It requires two separate motions to open, which means clever paws cannot accidentally trip the mechanism. My terrier, who treats every latch as a puzzle to solve, was genuinely stumped by this design.

The blow-molded panels are thick and resist deformation even when a dog leans hard against them. I set this up on my tile floor and the suction cups held the pen firmly in place during a full day of puppy activity. The same suction cups were less effective on my hardwood floor, which is a common complaint across suction-cup-based pens.

Assembly took me just under 5 minutes, and the snap-lock joints clicked together with satisfying certainty. The panels are only 2 centimeters thick when disassembled, which means this pen stores flat in a closet or under a bed without taking up meaningful space.

The 4-centimeter bar spacing prevents head entrapment, and the door opens inward to prevent dogs from pushing it open. These are the same safety features found on the NEWBULIG, and they both come from the same manufacturing approach to plastic panel design.

Best For Small Dog Households Under 44 Pounds

The Sweetcrispy handles small breeds, puppies, and calm medium dogs up to about 44 pounds. If you have a Shih Tzu, French Bulldog, Cocker Spaniel, or similar sized breed, this pen provides reliable indoor containment at an excellent price.

Consider Floor Type Before Purchasing

The suction cups work great on tile, linoleum, and sealed concrete but struggle on textured hardwood and matte-finish floors. If your home has mostly wood floors, you may want to add non-slip rug pads under the pen or look at a heavier metal option that stays put through weight alone.

11. BestPet 16-Panel Metal Exercise Pen – Best Expandable Option

The BestPet 16-Panel Metal Exercise Pen is the largest configuration in this roundup, and it is designed for situations where you need maximum area. With 16 panels, I was able to create a pen large enough for two medium dogs to have separate sleeping and playing zones without crowding.

The expandable design is the core selling point. You can use all 16 panels for a massive enclosure, split them into two separate 8-panel pens, or combine multiple sets for even larger spaces. I appreciate the flexibility, especially for multi-dog households or people who host dog playdates.

Setup is tool-free and follows the same rod-connected design as most wire exercise pens. You shape the panels into your desired configuration and connect the ends with the included vertical rods. The panels can form a square, rectangle, or octagon depending on your available space.

The rust-resistant finish held up during my testing period, but I noticed reviews from long-term users reporting rust issues after extended outdoor exposure. This pen is best used as a semi-permanent outdoor fixture or moved indoors during wet seasons to preserve the coating.

Best For Large Outdoor Spaces and Multi-Dog Homes

The 16-panel configuration gives you more layout options than any other pen in this roundup. If you have the yard space and multiple dogs, this pen lets you create a genuine exercise area rather than just a containment zone. The 40-inch height handles most breeds.

Be Aware of Durability Limitations

The connecting rods are thinner than those on the FXW or VISCOO pens, and they can bend under sustained pressure from large dogs. BestPet does not sell replacement poles separately, which means a bent rod compromises the entire structure. Consider this a budget large-format option rather than a heavy-duty one.

12. Amazon Basics 8-Panel 24-Inch Playpen – Best for Small to Medium Dogs

The Amazon Basics 8-Panel 24-Inch Playpen is a newer addition to the Amazon Basics line, and it offers a shorter, more manageable alternative to the 30-inch model I reviewed above. I tested this with my sister’s Beagle puppy, and the 24-inch height was perfect for a dog that was still growing into her legs.

The auto-locking door latch is a standout safety feature. The door swings shut and latches automatically, which eliminates the risk of accidentally leaving the gate open. The rounded edges throughout the pen prevent paw scrapes and snagging, which I appreciated during energetic play sessions.

Assembly is genuinely tool-free and takes just a few minutes. The metal panels connect with simple rod connectors, and the step-by-step instructions walk you through the process clearly. I had this pen standing and ready in about 5 minutes from opening the box.

The foldable design disassembles into a compact flat-packed bundle for storage. This is one of the easier pens to break down and stash in a closet or garage when not in use. The included ground stakes provide stability on grass, though they only extend about 6 inches into the soil.

Best For Growing Puppies and Small to Medium Dogs

The 24-inch height and 48-by-48-inch footprint work well for puppies who are too small for taller pens and for small to medium adult dogs that are not jumpers. The expandable design means you can combine multiple sets as your dog grows or your space needs change.

Indoor Stability Requires Attention

Without ground stakes, the pen shape can shift when dogs push against the panels. Indoors, I recommend placing the pen in a corner or against walls to provide natural bracing. The auto-locking door is a genuine safety advantage over manually-latched designs.

How to Choose the Right Dog Playpen

Choosing among the best dog playpens comes down to matching the pen to your specific dog and your specific situation. After testing 12 different models, I can tell you that the wrong pen is worse than no pen at all, because a failed containment attempt teaches your dog that escape is possible.

Size and Height: The Most Critical Factor

Your dog’s height and jumping ability should dictate your pen height. A 24-inch pen works for toy breeds, puppies, and small dogs under 20 pounds. For medium dogs or any breed with jumping tendencies, you need at least 30 inches. Large breeds, athletic dogs, and known escape artists require 40 inches or taller.

The general rule I follow: the pen wall should be at least 1.5 times your dog’s shoulder height. This gives enough clearance that casual jumping attempts fail, though determined climbers may still need a covered top.

Material: Metal, Plastic, or Fabric

Metal pens offer maximum durability and escape resistance. They handle chewing, pushing, and weather exposure better than any other material. Choose powder-coated or electroplated metal for rust resistance if you plan outdoor use.

Plastic pens are lighter, easier to assemble, and aesthetically friendlier for indoor use. They work well for calm dogs and puppies but will not contain aggressive chewers or large breeds. The snap-together assembly takes seconds compared to metal pen rod systems.

Fabric and mesh pens prioritize portability above all. They are perfect for travel, temporary setups, and small dogs. Never use a fabric pen with a chewer, a large dog, or a dog that has not been trained to accept containment.

Indoor vs Outdoor: Match Your Environment

Indoor pens benefit from suction cups, non-slip feet, or sheer weight to stay in place. Plastic pens with suction cups work well on tile and sealed floors. For hardwood, look for heavier metal pens that stay put through mass alone.

Outdoor pens need ground stakes, rust-resistant coatings, and enough weight to resist wind. The FXW Rollick and VISCOO pens in this guide are my top outdoor picks because they combine all three features. Fabric pens should only go outdoors in calm, dry conditions.

Escape-Proof Considerations for Clever Dogs

If your dog is an escape artist, you need a tall metal pen with a gravity-locking or multi-step latch door. The FXW Rollick’s gravity lock and the Sweetcrispy’s double sliding latch are the two hardest mechanisms for dogs to defeat. Avoid pens with simple flip latches or push-button releases.

Reddit forums are full of owners asking how to contain jumping and climbing dogs. The consensus from real owners is clear: height matters more than anything, and 40 inches is the minimum for determined jumpers. Some owners add mesh tops to prevent climbing escapes.

Portability and Storage

If you plan to move your pen daily or take it on trips, weight and foldability matter enormously. The Siedihit pop-up tent wins on portability at 3.3 pounds. Among metal pens, the VISCOO at 27 pounds with a carrying bag is the most travel-friendly serious option.

For storage, look for pens that fold flat. Wire panel pens that break down into individual panels take up minimal closet space. Plastic snap-together pens also store well, since the flat panels stack neatly.

Floor Protection: Do Not Skip This

One of the most common complaints in dog playpen reviews is floor damage. Metal pen poles can scratch hardwood and tile, and energetic dogs pushing against walls can drag plastic pens across delicate surfaces. Look for pens with included floor caps or suction cups, and consider adding felt pads or a rug underneath any pen on hard flooring.

FAQs

Wrapping Up the Best Dog Playpens for 2026

After testing 12 dog playpens across three months with dogs of every size and temperament, my top recommendation remains the FXW Rollick Unleashed for its unmatched combination of sturdiness, height, and build quality. For budget-conscious buyers, the Amazon Basics Foldable Metal Playpen delivers outstanding value at under $50 with over 78,000 reviews backing it up.

The best dog playpens give your pet a safe space to play and rest while giving you peace of mind. Whether you need a heavy-duty outdoor enclosure, a portable travel pen, or an aesthetic indoor solution, one of the 12 options in this guide will fit your needs and your dog perfectly.

Choose based on your dog’s size first, then match the material and features to your specific situation. A pen that contains a calm Chihuahua puppy will not hold a determined Husky, so be honest about your dog’s behavior before you buy.
