Won’t buy again
Size: Tripod, Size: Tripod
It started out great. But then it came apart and my puppy almost swallowed the piece that makes noise. Otherwise, it’s been a good brand of bones. Just not this particular one. The end unscrews and came apart. Not great!

Not for super aggressive chewers
Size: Tripod
Had high hopes, but our super-chewer somehow manages to UNSCREW the ends of the toy. Had to throw it out so she wouldn’t choke

Great Chew Toy
Size: Tripod
Has been great for our medium sized dog who loves to chew everything. We didn't realize it makes a sound too, which helps keep his attention. So far it has held up well.
