Always supervise your pet with any treat or toy
Bought 2 of these. Kept one for our dog and sent one to a friend as a Xmas present for her dog. Ours worked, but the gift never did work. Embarrassing, so replacing it with a toy and blanket. Don't waste your money!!!
Ball was great for about ten throws then it just stopped working. I purchased my second one last night to give it a final chance
