"I have a Boston/Staffordshire mix who chases very few balls. She LOVES these, we tug and she fetches. We play in the park, on the basket ball court or in the snow. The ball is very tough, but she eventually rips the handle off. It does not matter, its now a chew toy and it still bounces somewhat. Who said dogs are color blind, red is her favorite. I have bought over 20 balls in the last 3 years."
