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.

Durable and fun!
Color: Michigan Wolverines
I’m impressed with this toy! My two puppies absolutely love it and it’s been a hit during playtime. What stands out the most is how durable it is. This toy has held up much longer than most of the others I’ve tried. Despite my puppies energetic play, it’s still in great shape! Plus, it’s the perfect size for them to carry around and chew on. Definitely a must-have for any Michigan fan with pups!
