MidWest QuietTime Cushioned Antimicrobial Dog Crate Mat, Black, Large

This is something grippy so the bed didn't slide forward in our travel crate. I got a Large rubber mat knowing it was bigger than travel crate, it's very flexible, so far I just folded it under, but the material feels like it would be easily cut and still hold it's shape (I know that's not Chewy's answer). You can see the sides flexed up in the crate and wouldn't need to be cut. I think the dog enjoyed it today- we drive 2 hours on country roads and I never heard him adjust positions as much as usual. As many have shown, this rubber mat is only suitable for dogs who aren't going to chew it. But for older dogs who would benefit from a little cushion and grip, or who may be a little nervous with car movement, I definitely recommend.

It is much quieter than the old hard plastic liner that came with the crate

My border collie has a hygrometer from laying on the hard crate bottom because he doesn’t tolerate a crate mat. This one was nice and cushioned but the second day he destroyed it. I guess it’s my bad because it did not say it was tough.
