These ball toys are awesome! I have heavy chewing dogs and they love balls. Every time I get a tennis ball it’s chewed up in seconds. These balls last so much longer. They bounce high and they are the perfect size for medium and large dogs. They are durable yet squishy she my dogs can chew them without them coming apart instantly. They have lasted months. Even when they get little chunks taken out I don’t have to worry because they are food grade.

Very good quality

They are firm enough for dogs to have them in their mouth but not to hard. They bounce nice and more then once. I will purchase again if my dogs wear theirs out

Very lightweight and not good for fetching

These balls are very lightweight. They feel like styrofoam. I try to use my Chuckit Chucker to throw them but they don't go very far and the wind will drift them in another direction as they are so light weight. Then, when my dog's saliva covers the ball, the moisture creates a suction in the launcher and the ball won't exit the chucker at all no matter how much force I put into the launch attempt. I guess they might be good for chewers, but not for throwing, if your dog likes to fetch. They would be good for throwing in the house as they won't damage anything.
