We have an 11-week old sharpei puppy at home. He is housebroken already, and takes walks very well for a puppy. He will be starting "puppy kindergarten", but he is already very sociable, good with kids, and friendly. We've got many compliments on his temperment from breeders and other owners. I have two questions though. a. Since he's a puppy, I understand that he wants to play, so a couple times a night I'll run him around the main level or the yard, let him chase me a bit, flip him on his back and tease him and wrestle with him. I don't let him bite me, but he of course tries to nip. What's a good way to communicate to him that playtime is over? Sometimes, I'll be in a hurry, and he is chasing me around and biting my socks and shorts or jeans. This seems especially bad in the morning. Am I playing with him too rough, or is there another way I should be playing with him, rules to follow or something? On a sidenote, he usually gets at least one, if not two walks a night. b. We got this guy from a breeder in OH, and I'm assuming since they had kids, he got table food. I understood that, and was patient with him, and he hasn't received a scrap of table food from me or my girlfriend, but I'm guessing that he was slipped some people food when my back was turned at some of the family gatherings we have brought him to. But, the begging is out of control! He has learned not to jump on furniture, but that rule goes out the window for food, he will jump and lunge for it, and stern "no's" are met with barking (about the only time he barks), he ignores toys, and is extremely annoying. I have considered putting him in his kennel every time we eat, but is there another way to get him to stop this?
