We have a 77lb goldendoodle who loves these. We’re lucky because he doesn’t chew on anything other than his toys, but when he starts on this…he really goes at it. It’s healthy, (not synthetic), doesn’t break apart, (no pieces to worry about him swallowing), it just perfect for him. The noise may get on your nerves but it’s a small price to pay to keep him from chewing on your furniture, shoes, or anything else a mischievous dog can find.

Little pieces break off

Color: Dogwood (Brown), Size: Large (Pack of 1)

My dog is obsessed with this. It does last a long time even given her strong chewing capabilities. I wish it was a little bigger. The main reason I rated it so low is when my dog is chewing on this it breaks off a little plastic peice and sometimes it hits the back of her throat making her cough so you have to supervise with this.

Great for aggressive chewers

Color: Dogwood (Brown), Size: Large (Pack of 1)

My dog is an aggressive chewer so they are great for her. I would love to have one a bit thinner so it could fit in a holder so it is easier for her to hold while eating. This keeps her busy and is long lasting. I have purchased these multiple times.

Put your aggressive Chewer dog to the test!

Color: A Red, Size: For Larege Dogs

A very tough toy to stand up to my aggressive chewer lab! It's a great value! The squeak is not annoying, and she's got to clamp down hard on it. It's a nice throw toy! It bounces once or twice but it still brings out the pup in our Dog! Not too small a nice size for a Lab or retriever
