Perfect for a hound puppy
I have a difficult time finding plush toys that won’t immediately fall apart AND doesn’t have any secret squeakers. It’s bigger than I expected, his long hound mouth can barely fit the body inside - and it is very thick that it satiates the bite and catch component. He absolutely loves it, he will bounce it, chase after it and then pass out for a nap once he is done. He knows the toy by name and brings a lot of joy.. Highly recommend.

My Dog's All-Time Favorite
This is the only toy my dog will fetch over and over until she's too tired to run. This is her all-time favorite toy. We have tried buying others to give her variety, and she just keeps going back to this one. She'll chase other toys once or twice and then lose interest. But this toy? She will chase it indefinitely. We've purchased multiple so we can have one in each vehicle for playdates at the park. 10/10

The one bone to rule them all
This bone is definitely the favorite of all the different rubber bones we’ve tried. In fact, we did a green rubber bone test of two we bought to replace an old one and it was a clear winner. I don’t think it’s a matter of the sqeaky getting damaged as some dogs may eventually puncture the bone itself and then it won’t squeak. My little goober has serious teeth and she cannot stop squeaking this one. Also it bounces and I can throw it pretty far.
