Here’s a picture of THE Rescue Mutt, Nina. She originated in Mexico before being transported to a rescue in Texas. She’s about 15 lbs and wiggly with a tail powered tongue (if the tail is moving, the tongue is darting out). I noticed recently her back paws are smaller than her front paws which makes it look like she’s always on her hind tippy-toes. She has a lot of dense hair on her fanny. She has about 4 different barks and a couple of other vocal sounds that range from yips to growls. She has longer legs than either a Corgi or a Weenie dog.
