Why We Recommend It: The Zinger Winger DX5000 is probably the toughest and most durable crate I've reviewed. I wouldn't call any crate 100% inescapable, but the aircraft-grade aluminum and stainless steel slam latches mean the DX5000 is a match for almost any dog. It's also lightweight (compared to other heavy duty models) and has lots of ventilation - the only downside is the price.
For that matter, purchasing an indestructible crate for a dog is the owner’s best decision. It offers your pooch a safe place that they can use whenever they want. The dog won’t see the metal bars as something that keeps him imprisoned – he will, instead, see them as an integral part of his small cave that keeps him protected from the outside dangers. In other words, he won’t see his new crate as a negative space as long as you use it appropriately.
If you want the very best escape proof crate with no exceptions, then this impact dog crate is it. The Impact Case Stationary represents the ultimate indestructible dog crate. Made in the USA from high quality and durable .063 aluminum makes this crate incredibly strong as well as being lightweight and easy to move. This crate is corrosion resistant and will last a great many years making it a sound investment. This is especially important considering dogs can live for up to 2 decades. IATA compliant for airline travel!
So I pet sit and crates are a must for those who aren't potty trained so I have a crate in every size and shape. My last 48 broke from wear and tear so I got this one and the price is good but the cage is sort of flimsy. This wouldn't be a brand I'd recommend for anxious dogs or those who try to escape. I have many metal crates and some are stronger than others but I think this one is one of the weaker ones. Still serves its purpose for the calmer dogs who won't paw at it.
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.)
