Quality could be better
Really cool product but quality is not the greatest. I have tried three times and my GSD destroys them within a hour. Feel the stitches are too light and easy to rip

Dogs love this toy!
I've purchased a couple of these and the dogs love them. Good for puppy teeth and adult chewers. Can be torn up but last for dogs that like to chew.

Beware not as described!
I have ordered these multiple times in the past because our pup loves them. However, what I received this time is much smaller than before and does not match the dimensions on the site (6 in versus the expected 9). Very disappointed since I ordered two and these are not cheap toys.

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.
