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.

My dog's favorite rubber toy
Size: Small, Style: Beef
One of my dog's favorite ever toys!! She is obsessed with everything playology but she never gets tired of the squeaky bones and the nubby bones. My only word of caution is to know your dog and if they're a big chewer be careful they dont eat pieces. She'll chew off chunks and spit them out.
