Love these crate mats for traveling and trials
Size: Large 36"x24", Color: White
I just bought my fourth Uligota crate mat. My dogs love them. I use them in their car kennels. The seem to really enjoy the ride better with the soft cushion. I wash them often. The first ones I bought 2 years ago are as good as new after washing and putting in the dryer.

Avoid the washer
Size: Small 24"x18", Color: White
I bought this for a 10 week old puppy. He had an accident on it and I washed it in the washing machine without the agitator and it left a mess. It is soft and chew resistant but I wish it had a removable cover.
