Tennis ball substitute?

have you tried the rubber Chuck-it brand ??? tennis are horrible for your dogs teeth and chewing all the fuzz is very detrimental to the teeth ... i have an ball-obsessed jack russell terrier and her teeth are all worn down and she had to have serious dental work done under anesthetic ... your dog might like the fuzz but it really is not good for them ... if you take the tennis away, the dog will play with something else ...
