I have a maltipoo(wifes choice) that was especially difficult to train, and hard headed. I thought it was because he was not especially bright, but turns out to be the opposite. I tell him get me a ball, he runs off and returns with a ball. I tell him get me his rope, same thing. In the morning he jumps on me and wants to go outside, when I want to snooze a bit, I say "go lay down", no pointing no body language to read he goes and lays at my feet for a while longer. Watched the attached video of chaser, and totally agree with one point made- play is the way to teach an animal, not food. Dogs love exercise, and training with food is a great way to make your dog obese, which will make exercise more difficult and its overall happiness reduced. My dogs are 10x happier when they hear "you wanna go for a walk?" than "do you want a treat?"
