Best for

Overview

["This MidWest exercise pen is a folding, single door pen that sets up to give a dog roughly 16 square feet of play space, and it's built for both indoor and outdoor use. The single door has a large opening and a secure latch, which makes it easier to get a dog in and out compared to pens with a smaller entry point.", 'Unlike the enclosed crates in this category, an exercise pen like this one is open at the top, so it works best as a contained play or rest area rather than a place to leave a dog unsupervised for long periods, especially if your dog is a jumper or climber. It folds for storage, which is typical for this style of pen.', "At $30.62, it's one of the more affordable products in this entire silo, and the numbers back up how widely it's used: 46,200 reviews at a 4.6 star average, with about 2,000 bought in the past month, easily making it one of the best proven products in this category."]

Pros

  • Exceptional review volume at 46,200 reviews with a 4.6 star average
  • 16 square feet of play space is generous for a 30 inch pen
  • Large door opening with a secure latch
  • Affordable price relative to its size and reputation
  • Works for both indoor and outdoor use

Cons

  • Open top design means it's not a substitute for an enclosed crate with an escape prone or jumping dog
  • Single door design is more basic than double door crates in this category
  • Best suited to supervised play rather than long unsupervised stretches

Performance notes

The 16 square foot play area is the main functional draw here, giving a dog considerably more room to move than a standard crate footprint, while the large door opening and secure latch keep it simple to get a dog in and out. Since it's open at the top rather than enclosed, it's best matched to dogs that won't try to climb or jump out.

What buyers say

With 46,200 reviews and a 4.6 star average, plus about 2,000 units bought in the past month, this is one of the most consistently well reviewed and widely purchased products in the entire dog crates and playpens category.

Frequently asked questions

Is this an enclosed crate or an open pen?

How much space does this pen give a dog?

MidWest lists it as providing about 16 square feet of play space at the 30 inch height, which is generous compared to a standard crate footprint of the same size.

Can this pen be used outdoors?

Yes, it's listed for both indoor and outdoor use, making it flexible for setting up a play area in a yard as well as inside the home.
