Yes, I agree with the answers here. Most all dogs strive to please their master. And just a "pat on the head" makes them so happy!
hand signs along with verbal to sit, stay or heel....the dogs pick it up very easy as long as you repeat it often.
Whenever I say "Hi 5" to my doggie, she lifts her paw....she was so easy to train when she was a puppy!....Now she will be 2 in July, and like a child, she's getting "a mind of her own" and sometimes disobeys me. As long as you make it known to the dog by saying "bad girl/boy" when they don't follow ur command, they usually hang their heads....and then repeat the command. It takes patience!
A trained dog is a happy dog! Pleasing you, their master, means the world to them.
