cute! Our Cocker loved clicker training as a pup (any reward based training is good). She loved rolling in the smelliest stuff she could find e.g. hedgehog poo and rotting salmon. She loved stealing socks and gloves. She was happy on walks in filthy weather, but always found the warmest, comfiest place in the house to settle down. She didn’t fetch balls (often), or swim (ever).
Just remember, they have been bred to work with a just bit of human input (unlike some working dogs) so they can be quite independently minded – stubborn even.
Also, your home, your rules. Some folks allow their dogs to sleep next to them on the bed without a problem, that’s not how we do it though.
