Good stuffed animal toy
Color: gray & blue, Color: gray & blue
This is a good toy. But it's not big as the picture shows it's rather small. Looking for bigger toy.

My dog loves this guy!!
Color: gray & pink
This is the cutest little guy and my dog loves him. He knows him by name, he is tough and holds up incredibly well. My dog can give it a good chew but no problem! Make more cute ones and we will give them all names for him to play with.

Cute and well loved.
Color: gray & pink, Color: gray & pink
My dog gives this 5 stars because she loves to destroy stuffies and this was no exception. She immediately removed the ears and tail, along with the little nubs that were supposed to be nostrils. I give is a few points because she still hasn't removed any legs. I thought it was so cute, and it is far less cute since my dog has had her way with it. She still loves it however…so it is a winner in our book. The photo is after only a couple hours of play
