One owner notes that the only major difference between this crate and higher-end models is that the door locks could potentially be opened if a dog pushes the lever with their tongue. And indeed, several owners have noted that the locks weren’t able to keep their Houdini hounds in check. However, one individual notes that you could simply zip tie or caribeaner the lock if escape is an issue.
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.
The pan on the bottom is plastic, making it easy to clean, but it holds up well and is durable. It’s suggested that you put some sort of padding in there for your dog to make sure he or she is extra comfortable. The sides of the cage are made of wire and there are secure side bolts to make sure it stays shut. The company suggests that the dog breeds you put in there should be between 41 and 71 pounds.
Those of us with bigger dogs know the struggle of trying to find best extra large dog crates that won’t be too small and constricting on our beloved pets. There's hardly anything pleasurable about seeing a dog squished uncomfortably into a tiny dog crate. My Australian Shepherd, Walter, is a very… enthusiastic dog. Walter, God love him, is wild. He wants to be a part of everything, even things that shouldn’t include him at all, such as taking a shower, baking, and sleeping.
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.)
