Whatever happened to your last one, the important thing to know is there's a back up ready. The Petmate Plastic Replacement Dog Crate Pan is available in a wide array of sizes that are designed to fit standard Petmate wire crates. Tough plastic material is ready for heavy use and is easy to keep clean. This pan features a generous lip to prevent food, water, and whatnot from spilling over the sides.
The Smithbuilt cage is well established. It has a tried and tested track record of many customer reviews. So you can feel comfortable with what to expect. Beware of other cheap cages that do not have a good number of customer reviews. You’ll have less reason to have confidence in whether it’ll be suitable or a complete waste of money, or even dangerous for your pet.
Overview: Another plastic kennel, this is good for at-home use or when transporting your dog. It measures 48 x 32 x 35 inches, which is a huge size for a crate. It also meets USDA and IATA (International Air Travel Association) standards for shipping animals, so it will be okay to travel with—though make sure to check with your airline. The maximum height is 34 inches for your pet.
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.)
