Keeps her busy!
Color: Medium size (5.9")
Our Molly loves this. Only thing is that it is a little too big for our Maltipoo, but she still tries to keep up with it.

Tough
Color: Medium size (5.9")
So far my dog hasn’t destroyed it! And it’s been a month. So I call that a win. Plus he loves it.

The toy is best for "non aggressive " chewers.
The seller is fantastic though!! They resolved an issue proactively, without being asked-something you don't see often. That level of integrity sets them apart, and I would absolutely buy from them again.

Do not waste your money

Not for aggressive dogs. I thought this was good for the money it’s not. My dog chewed this up in less than a minute. Not too happy
