Big and Squeaks and Tough BUT Dog Destroyed it in 3 days!!
Size: Tripod
The pitbull who is an agressive chewer LOVES this and it squeaks! Highly recommend this large sized chew toy. BUT in 3 days the dog destroyed it. It is now in 6 pieces. But it still squeaks. I guess I can't recommend this because it is NOT durable.

Great chew toy
Size: Tripod
This is great and my dog loves it. He is 7months old and is a golden doodle. He loves to chew and was starting to destroy other toys. This is great for him to get to chew and it makes noises so that keeps him engaged for a while.

Great for aggressive chewers
These are some of the strongest bones I've ever seen. I have aggressive chewers and my puppy loved this bone. She lays on the garage and goes to town on it, not making any marks or chards or breaks like we do often have to deal with. They are long lasting as she has been chewing on it for a month now - well worth the money.

Great chewy for my dogs
My 3 dogs love these already. I smeared peanut butter on one side and passed them out. My 2 that aren't crazy active or aggressive chewers enjoyed the PB, then were done for now. Energizer bunny dog has now claimed all 3 and is alternating which one she chews on. Great buy for keeping them, especially her occupied.
