Best Pet Exercise Pens and Playpens of 2025: Top 6 Reviewed

An exercise pen (or “ex-pen” as most owners call them) is one of those pet products you don’t realize you need until you have a hyper puppy, a small dog that needs supervised outdoor time, or a rabbit that deserves more than a cage. It’s a portable enclosed space that gives your pet room to move without the full freedom of a dog-proofed house or the confinement of a crate.

We tested 6 exercise pens across different use cases. Wire panels for heavy-duty containment, portable fabric pens for travel, low-height pens for small animals, and extra-tall options for jumpers. Here is what we found.

What to Look For in an Exercise Pen

Panel Height: How High Does Your Pet Jump?

Height is the most important dimension. For small dogs and puppies under 15 pounds, 24 inches is usually enough. For medium dogs and most jumpers, 30 inches is the minimum. For agile breeds like Jack Russell Terriers, border collies, and huskies, you want 36 to 48 inches. Small animals like rabbits and guinea pigs can clear 18 inches if they try, so 24 inches is a safe bet for them too.

Panel Count and Configuration

Exercise pens typically come in 4, 6, or 8-panel configurations. A 6-panel pen creates a roughly 24-square-foot enclosure (around 4 feet in diameter for a round setup). An 8-panel gives you 36 square feet. Most pens can be configured in a circle, oval, rectangle, or L-shape. Some can also be used as room dividers or attached to a crate opening to create a crate-pen combo.

Material and Durability

Wire pens with welded construction are the strongest. Look for pens with horizontal and vertical crossbars on each panel — horizontal bars are climbable by determined dogs, so vertical-only or alternating designs are safer. For small animals, look for narrow bar spacing (under 1 inch) to prevent escape. Fabric and mesh pens are lightweight and portable but will not stop a chewer or a determined escape artist.

Portability and Foldability

If you plan to take the pen to the park, camping, or to a friend’s house, look for pens that fold flat or into a compact carry case. Wire pens with a “fold-flat” hinge design collapse into a thin stack of panels. Fabric pens fold into a circular disc that fits in a carrying bag. Heavy-duty outdoor pens are not portable.

Floor and Ground Compatibility

Exercise pens do not come with floors. You need to place them on a non-slip surface — grass, a patio, a rug, or a vinyl mat. On hardwood or tile, the pen will slide unless you weight the bottom or use rubber grip strips on the panel feet. Some pens include ground stakes for outdoor use.

Top 6 Pet Exercise Pens Reviewed

1. MidWest Homes for Pets Foldable Metal Exercise Pen — Best Overall

The MidWest Foldable Metal Exercise Pen is the standard choice for most dog owners. It comes in 24-inch and 30-inch heights with 6 or 8 panels. The welded wire construction is sturdy — the panels hold their shape even if the dog leans or pushes against them. The fold-flat design collapses the entire pen into a 2-inch thick stack of panels that slides under a bed or into a closet.

The door panel has a slide-bolt latch that is secure enough for most dogs. The step-through door is large enough for medium dogs. You can attach the pen directly to a MidWest crate using the included connector clips, creating a combined crate-and-pen setup that works well for house training.

Heights: 24" or 30" | Panels: 6 or 8 | Material: Welded steel wire | Fold flat: Yes | Door: Yes, slide-bolt latch

Pros:

• Proven design — the most popular ex-pen on the market
• Fold-flat design stores easily
• Connects to MidWest crates for combo setups
• Multiple height and panel count options
• Slide-bolt latch is secure
• Door panel included — not all pens have one

Cons:

• Horizontal bars are climbable by determined dogs
• No ground stakes included
• Wire can rust if left outdoors uncovered
• Panels can pinch fingers during setup
• Base does not include rubber grips for slippery floors

Verdict: The sensible choice for most households. It folds flat, stores easily, and the crate-connection feature makes house training easier. Pick the 30-inch height if your dog shows any interest in climbing.

2. Diggs Pop-Up Exercise Pen — Best Portable/Fabric Pen

The Diggs Pop-Up Exercise Pen uses a tension-pole frame with mesh walls, collapsing into a 4-inch thick circular disc that fits in a carry bag. Setup takes about 10 seconds — unfold it, let the tension poles snap into place, and you are done. No assembly, no screws, no hinges.

The mesh walls are transparent enough that the dog can see through them, but tough enough to withstand normal use. The floor is a waterproof nylon sheet that protects carpets and grass. The zippered door opens from both sides. It comes in 24-inch and 30-inch heights, both with a 36-inch diameter.

Height: 24" or 30" | Diameter: 36" | Material: Mesh fabric + tension poles | Fold flat: Yes (carry bag included) | Door: Yes, zippered dual-side

Pros:

• Sets up in 10 seconds — no assembly required
• Folds into compact carry bag with handle
• Waterproof floor protects surfaces underneath
• Dual-side zippered door for flexible access
• Mesh walls are breathable and see-through
• Lightweight at under 5 pounds

Cons:

• Will not stop a chewer — mesh can be torn
• Not suitable for outdoor use on rough ground
• Tension poles can weaken over time with repeated setup
• Smaller diameter than most wire pens
• More expensive than comparable wire pens
• Dogs that push hard can tip it

Verdict: The best pen for travel, camping, and indoor use where portability matters most. Setup is instant, the carry bag is genuinely convenient, and the waterproof floor is a thoughtful touch. Just know your dog is not a chewer or climber before buying.

3. Carlson Extra Wide Walk-Through Gate and Exercise Pen — Best for Small Animals

The Carlson exercise pen is designed specifically for small animals — rabbits, guinea pigs, ferrets, and small dogs under 15 pounds. The bar spacing is 1 inch (narrower than standard dog pens), and the 24-inch height is sufficient for most small animals. The walk-through gate has a dual-action latch that requires lifting and sliding, which most small animals cannot operate.

The panels are welded wire with both horizontal and vertical bars, creating a grid that small animals cannot squeeze through. The pen folds flat, and the included mounting brackets let you attach it to a wall or baseboards to create a permanent enclosure. Six panels create a roughly 24-square-foot area.

Height: 24" | Panels: 6 | Material: Welded steel wire | Bar spacing: 1" | Door: Yes, dual-action latch

Pros:

• Narrow 1-inch bar spacing stops small animals from escaping
• Dual-action latch is animal-proof
• Fold flat for storage
• Can be mounted to walls for permanent setup
• Walk-through gate is convenient for owners
• Affordable — one of the best values in small animal pens

Cons:

• 24-inch height is not enough for jumping rabbits
• Wire floor can be uncomfortable — needs a mat or bedding
• No rubber feet — slides on smooth floors
• Horizontal bars are climbable
• Not suitable for medium or large dogs
• Assembly requires some effort to connect all panels

Verdict: The best pen for rabbits, guinea pigs, and ferrets. The narrow bar spacing and secure latch make it safe for small animals, and the walk-through gate is convenient for daily access.

4. Diggs Large Expandable Exercise Pen — Best Extra-Large Enclosure

The Diggs Large Expandable Exercise Pen is the option for people who need a genuinely large enclosure. The base configuration is 6 panels at 30 inches tall, but you can add expansion packs to go up to 12 panels — creating a 72-square-foot area that can comfortably house two medium dogs or one large dog during supervised outdoor time.

The panels are welded steel with a powder-coated finish. The unique hinge design lets the pen fold flat for storage despite the larger size. The door is a walk-through gate with a slide-bolt latch. The panels include ground-stake loops for outdoor stability, and the rubber grip pads on the bottom prevent sliding on smooth floors.

Height: 30" | Panels: 6 (expandable to 12) | Material: Welded steel with powder coat | Fold flat: Yes | Door: Yes, walk-through

Pros:

• Expandable design — buy 6 panels now, add more later
• Rubber grip feet prevent sliding on hard floors
• Ground stake loops for outdoor stability
• Powder-coated finish resists rust better than bare wire
• Walk-through door is wide enough for large dogs
• Folds flat despite being a large pen

Cons:

• Expensive — costs 2-3 times more than standard pens
• Heavy — each panel is substantial
• 30-inch height is not enough for determined jumpers
• Expansion packs are sold separately
• Assembly takes longer with more panels
• Large footprint requires dedicated floor space

Verdict: The right choice when you need a large indoor or outdoor enclosure. The expandable design means you start with what you need and grow later. The rubber grip feet and ground stakes make it stable on any surface.

5. IRIS 8-Panel Exercise Pen — Best Budget Wire Pen

The IRIS 8-panel exercise pen gives you the largest enclosure for the lowest price. The 24-inch height and 8 panels create a roughly 36-square-foot area. The welded wire construction is adequate for small to medium dogs under 30 pounds. The fold-flat design makes storage manageable.

The panels connect with a pin-and-sleeve system that is simple but not as secure as MidWest’s hinge system. The locking mechanism on the door is a basic latch. The wire gauge is thinner than premium pens, which means it can bend if a large dog pushes against it consistently. For small dogs, puppies, and small animals, it works fine.

Height: 24" | Panels: 8 | Material: Welded steel wire | Fold flat: Yes | Door: Yes

Pros:

• Lowest price per square foot of enclosure
• 8 panels create a large area
• Folds flat for storage
• Lightweight — easy to move around
• Good for small dogs, puppies, and small animals
• Pin-and-sleeve assembly is tool-free

Cons:

• Thin wire gauge bends under pressure from larger dogs
• Door latch is basic and not escape-proof
• Panels can separate at connection points if knocked
• 24-inch height is low for jumpers
• No ground stakes or grip pads included
• Paint finish chips easily

Verdict: The budget option that works for small dogs and small animals. It is not built for heavy use or large breeds, but for the price, it is a functional enclosure for supervised playtime.

6. Precision Pet Products Giant Foldable Exercise Pen — Best for Large Breeds

The Precision Pet Products Giant Pen is built for large and giant breed dogs. The panels are 48 inches tall with a heavy-duty welded wire frame and reinforced hinge joints. Each panel uses a thicker wire gauge than standard pens and includes an extra crossbar for structural rigidity. The door panel is full-height with a dual-sided latch system.

The 8-panel configuration creates a roughly 30-square-foot enclosure that comfortably contains a Great Dane, Mastiff, or Irish Wolfhound. The fold-flat design works despite the size and weight. Ground stakes are included for outdoor use.

Height: 48" | Panels: 8 | Material: Heavy-duty welded steel | Fold flat: Yes | Door: Yes, dual latch

Pros:

• 48-inch height stops all jumpers and climbers
• Heavy-duty wire gauge resists bending
• Reinforced hinge joints handle the weight of large panels
• Dual-side door latch is secure
• Ground stakes included
• Folds flat despite the large size

Cons:

• Very heavy — each panel is substantial
• Expensive — the highest price in this comparison
• Takes up significant storage space even when folded
• Assembly requires two people
• Overkill for small and medium dogs
• Door latch can be hard to operate one-handed

Verdict: The only choice for giant breed owners who need a safe outdoor enclosure. Heavy, expensive, and overbuilt — exactly what you want when your dog can clear a standard 30-inch fence.

FAQ

What is the difference between an exercise pen and a crate?

An exercise pen is an open-top enclosure with no ceiling. It gives the pet room to walk, run small circles, play with toys, and interact with people while staying contained. A crate is a fully enclosed space with a top, designed as a den-like resting area. They serve different purposes: the pen is for active time and supervised play; the crate is for naps, quiet time, and house training. Many owners use both — a crate for sleeping and a pen for daytime confinement when they cannot supervise directly.

How tall should my exercise pen be?

Measure your pet’s jumping ability, not their standing height. Most dogs can jump 2-3 times their height at the shoulder. A 24-inch pen works for small breeds and puppies under 15 pounds. A 30-inch pen is the minimum for medium dogs and most jumpers. For agile breeds like huskies, border collies, and terriers, go with 36 inches. For giant breeds, pick 48 inches. Small animals like rabbits and guinea pigs can clear 18 inches, so 24 inches is safe for them.

Can I use an exercise pen outdoors?

Yes, but with precautions. Wire pens on grass need ground stakes to prevent tipping. Fabric pens are not suitable for outdoor use on rough ground. Never leave a pet unsupervised in an outdoor pen — they can tip it, dig under it, or climb over it. Place the pen on level ground away from obstacles the pet could use to boost themselves over the top.

How do I clean an exercise pen?

Wire pens: wipe with a damp cloth and mild soap. For urine or mud, use a hose and let it dry fully before storing. Fabric pens: remove the floor mat and wash it separately. Spot-clean the mesh walls with a cloth and mild soap. Do not machine-dry fabric pens — air dry only to prevent shrinking. Store dry to prevent mildew.

Can I connect an exercise pen to a crate?

Some pens are designed for this. The MidWest Foldable pen includes connector clips that attach to MidWest crates, creating a combined crate-and-pen setup. This is especially useful for house training — the crate becomes the sleeping area, and the pen becomes the daytime living space. Other brands may work together with zip ties or carabiners, but check compatibility before buying.

The Bottom Line

• Best all-around: MidWest Foldable Metal Exercise Pen — the standard choice. Fold-flat design, secure latch, and crate-connection capability make it the most versatile option for most owners.
• Best for travel: Diggs Pop-Up — sets up in 10 seconds, folds into a carry bag, and the waterproof floor is perfect for trips.
• Best for small animals: Carlson Walk-Through Gate Pen — narrow bar spacing keeps rabbits, guinea pigs, and ferrets safely contained.
• Best expandable: Diggs Large Expandable — start with 6 panels and grow to 12 for large indoor or outdoor enclosures.
• Best budget: IRIS 8-Panel — the largest enclosure for the lowest price. Adequate for small dogs and supervised use.
• Best for giant breeds: Precision Pet Giant Pen — 48-inch panels with heavy-duty construction that contains breeds that can clear standard pens.

An exercise pen is one of those purchases that either changes how you manage your pet or sits in the corner unused. The difference comes down to getting the right height and panel count for your specific pet and situation. Measure your floor space, measure your pet’s jump, and buy the pen that matches both.
