Best chew toy
Size: Medium (Pack of 1)
Kong toys are the best. They hold up through the heavy chewing stage. Definitely recommend if you have a heavy chewer.

Not for aggressive chewers
Size: Medium (Pack of 1)
My dog absolutely loved this Kong Goodie Bone at first and was super excited about it. Unfortunately, it didn’t hold up nearly as long as I expected. Within just a few hours she had already torn pieces off of it, and I ended up finding little red rubber pieces all over the house.
I wouldn’t recommend this for aggressive chewers at all. It may work better for lighter chewers or dogs that are gentler with toys, but mine destroyed it way too quickly. Disappointing because she really did enjoy it while it lasted.

Very sturdy for good chewers
Size: Medium (Pack of 1)
My dog loves this. Shes a boxer Old English Bulldog mix and she’s a hard chewer. We put Kong treats in here when we leave and she’s on it in no time

Dog toy
Size: Large (Pack of 1)
Very stable for my standard poodle. He loves the red Kong ball more because he loves to toss it himself
