I look at many obese dogs in parks etc all have in common vets and owners and other walkers that do treats all the time, these dogs suffer as do their joints in later life, if a dogs base nature is appealed to that dog cannot be blamed for behaving like a scavenger, a dog should learn to do things as part of a team, I personally do not treat my dog with food outside the home nor do I permit vets or any other person to feed him snacks treats etc, my dog has continual positive reinforcement with praise. I have terrier which has a nature to probe and scavenge, pension due to high prey drive and survival if holed up for length of time. And in a personal note, I see my dog as a partner in our team, it feels patronising controlling him with food, I like him to be on board so it's a big no for me outside the home..
people who let their dogs get overweight, will let them get overweight regardless of whether they use treats in training or not I'd imagine.
