In your opinion what should constitute *over dressing* a dog ~ should owners be prosecuted?

This is absurd. I have dachshunds, one a smooth haired and the poor thing tries to crawl up my pantleg in the cold weather, even WITH a jacket on. They get cold, too, boots and jackets are great in cold weather for dogs. It doesn't restrict movement. If the dog didn't mind it, trust me, they'd let you know!!
