I've got a 1 year old Brittany that has a problem that is getting out of hand. He'll chew on everything! It's gotten so bad that he's got to stay in his kennel any time someone isn't outside with him. I want to let him be free to roam the fenced in back yard but any time he's out unsupervised he's ruining something! He knows he shouldn't because every time he's done something and sees me he'll cower. It's led to hundreds of dollars in toys, shoes, lawn chairs, etc. I've bought him chew toys and bones and he stays interested in those for a short period then continues to chew. It's getting to the point of questioning why I have him because if he's not in his kennel then he's ruining something! Help! The kids love to run around and play with him. Any suggestions will be helpful
