We had collars on our small dogs. They chewed through their collars and their sisters' collars. We tried a harness and they chewed through that too. Unfortunately, they will chew through each others collars and/or harness so there isn't much we can do. We have a fenced yard and just don't put collars on the dogs anymore.
In your situation, if they continue to chew through the collars, and you need to have a collar on them, then you might have to resort to some sort of metal collar or chain that they cannot chew. Not ideal I know, but you may not have a choice. Good luck. |
