My little Harley visited with her trainer today and she told me that Harley is very bossy. She does this back talk thing with her voice too. She is also incredibly headstrong. More than usual. She is definitely a dominate female. The trainer taught me a technique where I roll her on her back and gently but firmly hold her chest until she submits and then praise the heck out of her. It seems to work to control her attitude and nipping. Harley is now 10 weeks old going on 5 years. lol I was wondering if anyone else had this issue and I also wanted to share this technique with everyone. It works for all doggies.
