my dog eats rubber

Rubber can be very dangerous for dogs. it does nasty things to their kidneys. I know this from experiance. My dog ate some rubber and we very nearly lost him. If not for the quick actions of our vet and a reasonable vet bill we were able to have him back. the thing about this is that its not a problem for him. It was just one of those things. In your case where it is becoming a recuring problem you may want your vet to check him out to see if he is lacking something. You may also want to get him into school where they work wonders on dog behavior Dale
