Sheba is not a chewer and her toys last forever.
I will never forget the time I took her to Dog Camp.
She had to be left in the crate for about an hour,
while we had a human meeting.
Sheba loves her crate but NEVER WITH the DOOR CLOSED!
She suffered anxiety and chewed up her crate bed and
drooled all over.

I felt so bad, I Never closed the crate door again.

Feel good that he is not suffering separation anxiety and he should grow out of it. I would give him cheap beds for now
or even an old blanket for his crate.
