I guess it is really great.....we all know what a picky little guy Mojo is, so anything that we can find or get that he loves, is really, really wonderful!
I didn't know about the blue rubbery stuff around it, but he doesn't seem to mind that.
The everlasting treat ball is on the top part and apparently it tastes really good...it doesn't smell...it is hard and I can imagine it will take FOREVER to lick it all away!
The other end holds small treats...like a puzzle treat ball....and when Mojo plays with it, etc.....every now and then a little treat will fall out....we are using Yorkie Yummies because they are small and healthy and Mojo will eat them. They work perfectly in the ball!
