Dog did not like it
Color: 6PC-Beef-Red
Not impressed at all. My dog is a toy and bone hoarder. She does not touch these bones at all, it sits there all day while she grabs all her other “treasures”

One TOUGH toy!
Size: Large (5" x 3.25" x 9")
The first of these toys survived 2 Huskies, an Aussie, 2 GSDs and our Pitmix, I only got a new one because first one is soooo old! It is a favorite toy and there would be unhappiness if it were not available. This is one TOUGH toy, great bounce and spin, we love this toy.

I bought this toy may 2025 it is now January 2026 I am finally having to replace . I have a chessie , almost 2 yo he is not an insane chewer but he does make the fabric “ tuff toys” look like a joke . Those are gone in ten minutes . This one last and last and last . It’s a great buy. In process of ordering my third one decided to write a review. I never write reviews . Such a simple product but worth every penny . My dogs favorite toy . Will stay in the arsenal .
