I purchased this chee toy bone by #GLANDU for my son's roommate's puppy which is a chewer. She's 16 weeks old and if left alone will chew up virtually just about anything in a matter of seconds. Since we gave this to her she's left my son's shoes and sandals alone and has concentrated on only chewing the bone. She's a pitbull and they're known for chewing and I only wish we had this when out pit was in the chewing phase. It would've saved us lots of money on shoes. Totally satisfied and I would definitely recommend this to anyone wh ok hasca chewer as a puppy. Thus really works!
