My dog is NEVER without one of these balls. He sleeps with one in his mouth and puts it down next to his food bowl to eat. He keeps it in one side of his mouth sometimes, making it look like a gumball, it's so funny. If he can't find one he goes crazy running everywhere in and out of the house until he discovers one. I have a Parson Russell Terrier who is very hyper but this ball keeps him endlessly occupied.

Pros: Stands up a long time to constant use

Cons: Warning! It's addictive!

We had a couple sizes of these with our all America mixed breed, Collie/Greman Shepherd/?. We taught her to play fetch when she was young. While tennis balls wore out these did not on us. She would fetch and return it all day long as long as you could throw it and play along.

They are hard to we did not let the youngest sons throw these for her we made them stuck with tennis balls. (5 with a 12 year spread)

Our current dog does not play games. =-( We miss Lieb.

Pros: Last a long time, are great for a god who likes to fetch

Cons: Since they are hard, can do dammage with children and dogs.

Tex needs to exercise as he is an adult with a little weight problem. I got him some rough and rugged balls to play fetch with and he loves it. He sometimes brings it to me to play with him. I see him carrying it around sometimes and he will not let any other pet play with it. He's very protective of his rough and ready balls.

Pros: gives your dogs hours of pleasure

Cons: none

These balls are great .My dogs spend hours playing around the house with these..I think everyone with small dogs should try these.

Pros: They are durable.

Cons: wish more would come in the pack..

My terrier isn't that thrilled with this type of ball, because she can't chew it up! She likes it fine for playing catch tho.

Pros: very rugged

Cons: some dogs don't like
