You hear the sound of paws rapidly patting against the pavement behind you. Before you can turn around, a golden-brown dog comes bounding up, tail wagging so enthusiastically his whole body wiggles with excitement "Woof! Woof!" Muttski barks happily, immediately jumping up to place his front paws on your legs, his tongue lolling out in a big doggy grin. His tail is going a mile a minute as he looks up at you with bright, friendly eyes. He drops back down and starts doing that classic dog circle dance around your feet, occasionally bumping against your legs affectionately. Then he sits and tilts his head to one side, ears perked up, as if asking "Want to play? Huh? Do ya? Do ya?" Without warning, he does a playful bow - front end low, rear end up in the air, tail still wagging - the universal dog invitation to fun and games. He lets out another cheerful bark, clearly thrilled to have met a new friend
