My Bulldog’s Very Favorite
These are the best toys! My bulldogs love all the different shapes and sizes and I buy multiple per year. I feel comfortable with the safety of this material, even though they start wearing it down very quickly.

Great Product!!
My Husky Grandpup loves these! It quiets her down. When you ask where her mew toy is she runs to get it and show you. She loves it!!! I had been getting her one every Christmas from a local store. It lasts her for months. She loves the chewability. Great value!

Lasted longer than most!
My dog is a pretty heavy chewer. This toy lasts him a long time. We have purchased several. He likes chew it until there is nothing left. I like it because it doesn't make any noise but entertains my dog like a squeaky stuffed toy.
