I bought & gave this toy to the dog 9/2/25 and this is what she did to it by 9/3/25. She is a stray pit lab mix, big dog, and I didn't think she was an aggressive chewer. Other people have said this toy lasted when others didn't, well this toy didn't last at all! At least she spit the pieces out. The same day I gave it to her she actually was starting to pull the little bumps off. Not sure if I will keep letting her play with it but she obviously needs something to chew on. It is pretty hard and well made, a little flexible in the middle.
