Duece, 4 months, has started chewing his leash. He usually always has one on even inside and he will not quit chewing/playing with it. I have tried redirecting him and it only lasts for a few seconds and he is back to playing with it. It is impossible to try and stop it as much as he does it especialy since he has it on 95% of the time he is out of his crate so is it ok to just ignore it or is ther something else I could try to get him to stop? Sometimes it seems the more I try to get him to stop the more riled up he gets.
