Why it's at #1? I chose to put Midwest Solution Series “Ginormus” Double Door Dog Crate as the first product on this list of best extra large dog crates because we found that it was actually the largest and easiest to clean. Also, the crates are stackable, which is something you don’t find with many crates today. All in all, this is a convenient, safe product for your dog.
Crates that don’t close securely are pretty worthless, so you’ll want to make sure that any crate you select has high-quality latches. But beware of crates with exceptionally large latching mechanisms, as some dogs will learn how to open the door themselves. If you have an especially escape-prone pooch, you’ll probably need a crate especially designed for Houdini dogs with double latches or more advanced locking mechanisms.
The ventilation, on the other hand, is solved by the addition of a generous number of holes in each side of the crate. Their purpose is to promote extra air flow and allow the owner to use the cage on warm days. The heat can also cause evaporation of toxic materials, but that’s not something you need to worry about with this model – no harmful chemicals were used during its manufacture.
Overview: This seventh best extra large dog crate has a single door and is made from five, seven, and nine-gauge mesh, making it very heavy-duty and durable. There are no tools required for assembly and its measurements are 49.5 inches long, 29 ½ inches wide, and 31 ¼ inches tall. There are three security locks on the door, eliminating the risk of easy escape. It is appropriate for pets weighing 85 pounds at most. The height of pets is recommended to be no taller than 30 inches.
Addendum added January 28, 2013: My vet had never noticed these carriers because I had never put one up on the exam table until my last vet visit. She looked at it with interest and totally concurred with my opinion of having a small, but open carrier for my two (panicky) cats. She has seen more than a few overheated pets in too enclosed carriers. Since I live far from the vet I always carry spare towels for the bottoms of the carriers and she found that the "stable floor covering'* I use was an additional comfort feature for my pets long trip to their appointments. (I just ordered the larger size of this carrier for my "Phat Kat" and will donate her previous carrier to our local animal shelter.)
