I have bull terriers. They chew wood for fun... But this brand in the appropiate size and in any shape has been the best thing for them! They last for a very long time (they have not even dented them and they've had one (another shape) for the last two years. Now I bought these bones so that they can play together, each graving one side of it. They have so much fun! They are worth every penny.

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
