I just adopted a red heeler from Nevada. She was found as a pup and is now 10 months old. VERY shy, afraid of people. The foster parent suspected she's an offspring of a red heeler and coyote. She's got the long legs, gait and very thin. She does "move" like a coyote... What are the chances she is? Is there anyway to know if she is. She also has what looks like eye liner around her eyes which I've never seen on a heeler. My cat's in another room till I know I can trust her. . .
