Our Chocolate Lab has really got to lose weight, vet warned us last time and we tried some diet dog food but he hated it and wouldn't eat it. With his bum leg he really hasn't gotten that much exersize this winter, he's turned into a big couch potato! With Spring almost here and his leg is a little better I am going to start his walks again but didn't know if anyone had any good idea's to help him lose weight, he's got to lose at least 10-15 lbs.
