Hi my little Max keeps chewing on every harness we get him. I just purchased one from Chattiesmom which she made for him and it did not last one day. Does anyone have any suggestions on how I can keep him from chewing his harness. Buying harnesses all the time is going to put me in the poor house. He also tends to want to explore outside of the confines of our backyard. Yesterday, he ran into the street only by some miracle he did not get hit. It disturbed me to no end and I was a nervous wreck. Can anyone please tell me what I am doing wrong that my dog wants to stray.
