Beware of tiny plastic pieces

Plastic too HARD!
Color: Georgia Bulldogs, Style: Goal Post Chew Toy
Plastic is extremely hard. Too hard for my puppy as is could crack his teeth.

Puppies love it!!!
Color: Michigan Wolverines
I’m so happy with this dog toy! It’s the perfect way to show off my team pride while keeping my puppies entertained. The toy is durable and holds up to lots of chewing and tugging. The Michigan Wolverines logo looks great and it's the perfect size for my pups to grip and play with. GO BLUE!!!
