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.

Dog toy

Very stable for my standard poodle. He loves the red Kong ball more because he loves to toss it himself

Best dog toy on the market

Size: Medium (Pack of 1)

Our blue heeler doesn't go anywhere without this bone. He can chew on it till the cows come home and he doesn't get through it. Rebar enjoys it, plays with it for hours, it's a perfect size for both small and medium sized dogs, doesn't squeak and is easy to throw and retrieve.
