I bought these balls for my 9 year old Doxie! The bill came to a little over $22.00! After given her a ballWithin 3 minutes it was ripped in half. The balls are paper thin and they should not cost what they did!They would be fine if she had no teeth. I just wish I knew how durable they were going to be. I wouldnot recommend them. For the cost of them, not worth the money at all . Very Dissapointed!
