My dogs loved these toys. Durable and apparently very coveted as my puppers “argued” over who got each one. Kept them playing and chewing for hours. Giving only 4 stars instead because I Wish the size was bigger because I have found that sometimes I don’t see it and stepping on it is Absolutely NO FUN.

Rottweiler approved

Color: Purple

My Rottweiler puppies love these bones. I feel good about letting them play with these and not worry they will break or that they can choke because they are durable and a good size and weight. I like the variety and can put peanut butter on the crevices if I want to give as a treat. Worth the money!

Perfect for the aggressive chewer

Color: Purple

I purchased these because I have a 1-year-old black lab redbone coonhound mix who destroys every toy and Bone. I have gotten him in a short amount of time... These things have outstanded this little guy and he is still enjoying them! Keeps him occupied and satisfies his chewing for hours! And he leaves my shoes alone haha
