My frenchies love this thing, they've had it for a month and its just now starting to wear down. Hopefully its safe to eat bc they've nawwed it down to the first post. 😅 Its easy for them to stabilize and really get to chewing. Would buy again

Great For Michigan Fans!
Color: Michigan Wolverines, Style: Goal Post Chew Toy
I got this toy for my puppies and it’s been a hit! Not only does it look great with the Michigan Wolverines design, but it’s also really durable. My dogs love chewing on it and it’s holding up really well despite their intense chewing. It’s the perfect way for any Michigan fan to spoil their furry friends while showing some team spirit. Definitely recommend it for dog owners who want something tough, fun, and stylish for their dogs!
