I love teaching tricks to my border collie, Emma, and she, in turn, loves learning them. She’s built up quite a repertoire, but I’m especially fond of her “wave hello” (right paw) and “wave goodbye” (left paw) tricks. As tricks go, they’re pretty simple; but she waves with such style and relish! What a comical picture she presents, with her wildly pedaling paw and her too-long tongue dangling from the right side of her mouth. I can’t help laughing when I see her.
