Pepper just turned 8 months old...and suddenly that dreaded teenage phase is kicking in. She was pretty good with her recall. I have been taking her to the dog park almost every morning. She plays with the same group of dogs everyday and loves it. She had been coming over to me whenever I called her....which included leaving the park ( always with treats though). Suddenly, the last 2 times she totally ignored me. She comes, takes the treat...and before I can get the leash on her....runs away again. I have very recently started putting on the prong on her for our walk to the park since she had been pulling too much. She only gets the prong for her walks. Do you think its because of that? ...or is she just asserting her independence? Oh yes, when we practice recall in our yard, she's perfect...comes every time. Its in the dog park, when her friends are around....she totally forgets. What should I do?
