Ruby has been a good girl since we got her one week ago (14 weeks today), but she has become very frustrating out in the back yard. We have to keep her on a short leash because she eats everything...grass, mud, rocks and cicadas, alive and dead. This habit has created a notable problem on the leash during walks as well. Her tracking is so intense she cannot regularly followthe heel and sit commands. I know she's a pup and this stuff happens, but I feel like I am dragging her around by the neck and/or overusing the "pop" on the heel command. Comments?
