About 10 years ago I purchased a Jolly ball for my corgi. She loved it and played constantly. I now have another, more petit, corgi and this same ball is also her favorite toy. I've been looking for a back-up, and this (6") was the Smallest size offered by EntirelyPets. BeeBee gave it a try, but it is just to big and heavy for her. I will donate it to the shelter and continue my search for the smaller (4 1/2") size. Conclusion: wonderful toy for a herding dog, but be sure to get the proper size.
I purchased this for my Newf, because he played with one at the park, that was owned by a French Bulldog. The bulldog used the handle, but my Newf just picks up the ball, leaving the handle for me to grab. It is sturdy, no damage so far, and he is a dog that kills every tennis ball he picks up.
I thought this would be a durable toy for my 8 month old Black Lab. She chewed apart the handle and maybe ate some of the plastic within hours. I would not recommend this to anyone. By the way this dog has "puppy" Kongs that are still in very good shape. I give her one each day and they hold up to her teeth.
My dog (a Jack Russell) absolutely loves this ball. Her life revolves around playing with her Jolly Ball. The "tab" on it makes it easy for her to carry and makes it easy for us to throw it. She also plays with it in the pool. I always keep one in reserve - she couldn't go a week without her little Jolly Ball!
