Folding dog crates are one of the most popular ways to move your pet around. The reason for this is simple a folding crate can be easily stored in the closet or in the attic. Most dog owners use a dog crate very rarly so it has to be easy to store away.
The folding dog crate that I have is metal wire that can be disassemble and flattened but there are plastic models that work the same way. The plastic dog crate well fold up into what looks like a briefcase and can be stored almost anywhere.
Crates are a necessary evil to most pet owers yet nobody wants to see there friend in a cage but for there safty and sometimes the safty of people around them it is a most. Some dog like being in the crate when 
traveling it makes them feel safe. With a little dog crate training your pet will not resist going in his or her 
crate.
There is also folding dog crates that are made of a water resistant material called Denier Polyester. These crates are also known as soft side crates and can be folded up very easily. This style crate works best with smaller dogs.
