Growling problems! Please help!
3 days ago I brought my passing grandfather's GSD, Holly home. She has always taken interest in me, and being an avid dog lover with plenty of time and space for her I decided to take her in. She's approximately 3-4 years old, wasn't trained or exercised, or introduced to more than a handful of people. She is very sweet and loving, and the past few days I've been working on training and getting her used to walking 2 times a day. Things are going well; however, whenever my boyfriend enters the room she's in, she growls and runs away from him. I know she is in a new home with lots of changes, but my boyfriend is getting irritated with her and feels like he will get bitten. He's tried getting down to her level, giving her treats, and talking in a high pitched voice. I am determined to make this work, as she had special meaning to my grandfather and I want to give her a forever home. I'm just confused and need some input to try to improve the situation. Thank you for any tips!
