As most of you know, I rescued Miley from a shelter about 3 months ago. She is such a great addition to our family. There haven't had any problems with her until now. Miley will not let any man except my husband in the house. When we are away from the house she is ok. Today she tried to eat the plumber. I was overwhelmed at her reaction! I introduced them outside first since I knew that she wasn't fond of men, she did ok. Growled under her breath at him a bit. Then we came inside and her demeanor changed from leary to "you should NOT be in here!". She showed her teeth and growled like I've never heard before. It didn't appear to be a fear aggression to me, I've seen that in other dogs. This appeared to be a territorial, protection thing. I didn't yelled at her or take her by her collar. I tried using my voice to let her know that it was ok and this person was aloud inside but it was no use. I ended up having to put her outside while he was here. Any ideas? Plumber will be here all week and I want to make things as pleasant as possible for everybody. Thanks!
