My 30 pound 7 month old puppy was tearing it apart.
Size: Jumbo, Style: Chicken, Size: Jumbo, Style: Chicken
I gave little Charlee back the bone for a size comparison. She's trying to rip off a piece that she chewed loose. This puppy is only 30 pounds and 7 months old. The bone is clearly rated for puppies up to 8 months old and 60 pounds. It is rated for dogs twice her weight and she was trying to pull chunks off of it. When she grows up she'll still be within the weight limit. There is a lot more damage than pictured and she may have eaten a couple of missing spikes. She is a strong and mildly destructive chewer, but this is unacceptable. I have a smaller version of this bone without the spikes and it has lasted months of gnawing, so I expected that quality to carry over to it's larger cousin. This was a big disappointment.

Very durable; aggressive chewer approves
Size: Jumbo, Style: Chicken
My dog is an extremely aggressive chewer so finding a toy that can survive more than a few days is never easy. This bone has done well for the last couple months. It’s a little bit larger and heavier than I was expecting but isn’t a problem for my German shepherd. It smells fine; at least it isn’t stinky. We play fetch and tug with this toy and there is very little wear and tear and only shows teeth marks. She will sit and chew on the toy for quite a while and seems content while chewing on it. Great tog

Helps With Teeth Cleaning
Size: Small, Style: Beef
Our dog loves chewing on this toy multiple times a day. I believe it helps with teeth cleaning. As we do not brush or add additives to water or food for teeth cleaning. Seems that vet is not suggesting to have teeth cleaned every visit anymore. The rubber is very durable. Last about 6 to 7 months before we start to see deterioration and have to replace.
