heavy duty quality
Color: Georgia Bulldogs
Bought for friends. They have a dog that will gnaw and chew on anything. This was very durable and lasted with constant chewing and playing.

Heavy
Color: Texas Longhorns
It’s a tough and heavy toy. Probably best for dogs over 10 lbs.

Way too easy for dogs to chew up
Color: Texas Longhorns
I have a black lab who likes to chew toys up. She destroyed this almost immediately with ease. It is not durable whatsoever to any chewing. Do not get.
