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.)
If your dog is escaping by forcing apart the crate seams, consider using carabiners or some other type of metal hardware to reinforce these places. Never use things through which your dog can chew, such as zip ties, rope or duct tape. Not all metal carabiners and similar connectors are dog-proof, but high-quality products usually are relatively immune to your dog’s jaws.
Pros: Customers who chose to take this on camping trips with them found that the mesh held up well against the elements and was mosquito proof. Other customers remarked on the space, finding that being able to put in their dog’s food and water bowls with them in the crate was very convenient. It’s also lightweight and easy to move, despite the size. It’s also very well ventilated and has good air circulation.
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.
The metal frame construction of the Pet Life 360-Degree Vista-View Soft Folding Collapsible Crate ensures ultimate durability when traveling. Mesh windows give your pooch a 360-degree view that he'll love, and multiple entrances make it easy on the both of you. A built-in leash holder keeps your pet from wandering off, and the duffle-style nylon handles make it easy for you to grab and go.
Update: We traveled quite a bit this holiday season and this portable crate was absolutely awesome! I have seen some reviews about bad zippers but suspect it's due to misuse. You have to raise each side before zipping it -- just common sense, people. Otherwise, there is too much pressure on the zipper. I think zippers on this crate are sturdy. Another suggestion is placing your dog's favorite bed inside. The crate (we have extra large) has plenty of room to add an extra large fluffy dog bed our dog loves. Because the crate folds flat, we place the crate in the cargo area and cover it with dog's bed when on the road. The dog sprawls like a queen! :) When we get to the destination, we unfold the crate, throw the bed inside, and voila -- cozy house that ... full review
