I’ve only owned hounds dumb and smart. I’ve been fortunate to teach them the basics with ease. BUT had a real good buddy with a old English lab. He sent him to school for all the basics. He worked all the custom commands so to speak. If we were out messing around he would keep a soft cooler or easy open cooler in his truck. “Winston get me a beer” he’d be back with one shortly. He kept him inside the house. Wrapped a towel around the fridge handle. Same results inside. And almost always every third beer was Winston’s when he was outside . Crush the un opened can and lap it up. Won’t teach a hound that. Best handler/dog relationship I have ever seen.
