My Chelsea used to roll the ball under the dresser and bark at it till I got it... she would do that over and over. she had me trained well..
My Chelsea is the past-mistress of the "Neener, neener!" game. Poor Jasper and now Humphrey just have to take it. When I give them rawhide treats, she ignores hers and even turns away. Then when Humphrey finishes his and comes inquiring about the "abandoned" treat, she spins around with a snarl and happily chews it up while he watches sadly.
Humphrey and I have a morning routine (as he doesn't get to sleep on the bed. . .yet) where I get out of bed and sit on the floor to hug him. He butts me with his head and makes little whuffly moaning noises, and eventually this big manly fellow flops on his back, feet flailing, lips drawn back and giving me "love nips"on my hands. (No lectures, they're really just love nibbles, its his snarly face that's funny.)
