Good quality, not a bad price
Size: Large, Style: Peanut Butter
Good value. It was cheaper to buy the pack of three instead of buying three separate. I wanted to try different shapes for the dogs. Honestly, they aren’t impressed, but it’s not due to a lack of quality of the product. It’s because they would rather shred Kleenex, eat dog poop, and steal chicken eggs.

My dogs love love love these
Size: Large, Style: Peanut Butter
Repeat buyer here. I have Blue Heelers and Aussies so I have purchased many of the jumbo balls and we have loved them. I decided to gift this set to a friend. The pups ages range from 4 months-11 years and they adore these toys, even sleep with them! If you want to train your dogs to play with toys instead of your belongings, you can't go wrong with this peanut butter trio!
