Cookies just met Milo. Milo is one of my clients from years ago. Milo has come for the weekend while his owner is on vacation. Milo used to have some serious problems, including leash reactivity, redirecting (biting his handler, when he was restrained and prevented from attacking another dog), and dog aggression. Now Milo is a cool dude. He is fully remote collar trained. These two dogs have been in "place" with each other for forty minutes already. No one has barked or whined. They have only politely sniffed each other. These are the results you get when you create calm structure. Dogs respect leadership. They quickly fall in line when provided with a path to follow.
