But It
Flavor Name: Peanut Butter, Size: Medium
My fur baby has his fair share of toys, but something about this one he won’t put down. Pieces fall off the ends once they chew on it for a while.

A hardy chew toy
Flavor Name: Peanut Butter, Size: Medium, Flavor Name: Peanut Butter, Size: Medium
My dog loves these! I have purchased several. The size is perfect for my 25-pound cockapoo. It’s durable and she chews them for months until they’re prickly and not as fun anymore. The price is reasonable enough and she loves them so well (they’re one of the two chew toys that she likes), so I feel like the cost is worth it. One thing to note is that my dog does chew off tiny bits from the bone. She usually spits them out but has swallowed some bits here and there. There hasn’t been a situation with the swallowed pieces, but I always monitor her as she uses it and would suggest that for other pet owners also. Safety is always key, but we have never had any problems in the two years I’ve been buying them.

Golden approves
Flavor Name: Peanut Butter, Size: Medium
Golden approves. Good size. Durability is hard, she did end up chewing the heck out of it. Great for puppies.
