re: Dog Training Question - Non Hunting Dog

Sounds like a pack order issue. She doesn't respect you as alpha if she has selective obedience. Go to leerburg.com and spend a few hours reading his articles, especially the article titled 'establishing pack order.' It was extremely informative for me with an adult male pitbull terrier we rescued last September. I've owned/trained bully dogs for 30 years and learned more there in 5 days than I had in the previous decade.
The process is a little inconvenient for 2 legged pack members but if you follow his advice you and the dog will appreciate it in 2 months.
