Mickey doesn't really beg, but he will nudge our legs and just stare at us. Sometimes he gets pieces of bread/crackers but not too often. He especially loves when we have watermelon. He always gets his own share so he just sits there waiting. I guess just teaching Tikeya and Oscar to go lie down or keep them in the stay position in another room would help. Or, as Ash suggested, just ignore them altogether when they beg. Sometimes I'll pat Mickey on the back when he passes by--I guess that's a mistake!
