Yes, that would be seperation anxiety.

Sierra used to do the same thing, then we got Buddy and she doesn't do those things anymore.
I lost count of how many blankets we went through!!
Once I left a wicker basket on top of her crate, and she chewed it up through the crate!!!

Just a few weeks back, when Buddy had to stay at the vet for the day, she freaked out, and got out of her crate!!

But, as long as she has her Buddy boy she's fine! She's had the same blanket in her crate now for a few months!!! That's a record for her!
