Awesome!!
My dog absolutely loves this toy. I normally fill it up with her kibble for her dinner and she will throw it around to get all the food out, we also throw some peanut butter or yogurt in it to spread on the sides so it will occupy her. She doesn't just sit and chew on this toy at all, but she loves to get her food out of it. It is a great slow feeder and puzzle for her!
I recommend giving it to your dog on hard floors if you can, when the outside gets slobbery at all it picks up a lot of hair and it sticks to the outside, just an FYI!
