A bored dog will shred just about anything. A dog doesn't really need anything soft to lay on. They're built to lay on whatever surface. You could place the crate on carpet or the like for some insulation if you think it's needed. Generally the plastic crates are pretty thin. We're using a Kong bed now and it's holding up to daily scratching and digging. But it's just a day bed in the living room. In the kennel where he sleeps at night is a basic fabric pad that gets replaced when he stinks it up.
I run my own dogs. Professionally trained but I handle them myself. Mostly run Hunt Tests but have ran Quals and Derbies with them. Tons of fun.You run your own dogs or have a pro handle them in the open for you. Hoping to run a qual if time permits this year.
Also had to switch to a dog cot because my old boy tore up every other bed he got. So far it’s been the most durableI use dog cots. We went through all kinds of dog beds before. The cots work well and the dogs seem happy
Plus you can hose them off.
