I'm having a bit of an issue between Molly and my partner's dad! When we first got Molly, she was terrified of everyone, it took almost 2 weeks before we could walk up to her in our backyard without her running away and she would only come up to you if she saw you patting Meika, and she's still a bit funny when she meets strange males, she will duck away when they try and pat her but she is getting better and she was all over a maintaince guy we had here last week which was great! She has never been agressive or showed any signs of agression, has just seemed scared and unsure.
A few months ago my partner's parents came to stay, she was great with his mother but would not go near his dad, and would put her hackles up and growl at him constantly and if he moved to another room, she would follow him, keeping her distance but growling the whole time. We tried getting him to feed her but he couldn't get close enough to her because she would just back away, not taking her eyes off him, and still growling. We tried putting her in time out too but while she was in there, whenever she heard him speak, she would bark. We put it down to her still being a bit scared of males (we hadn't had her long at that stage) so we just did our best to keep her seperated from him.
Then last night he came to stay again, this time I tried to act really calm because he's not my faviourite person ever and I thought that maybe last time she could sense that. When he got here she ran straight up to him and was all loving and wanting pats etc, then we moved inside and as soon as we got inside, the hackles went up and the growling began again but this time she was barking aswell. I put her straight back outside for timeout, and she stood at the door barking, then when my partner got home she ran through the door, straight up to his dad and started the barking/growling display again so she went back outside and continued to bark at the door all night until it was time for her to go into the garage for bed, then she barked whenever she heard him speak again.
I was at work when he left this morning so I'm not sure how she acted then but I assume it was the same barking/growling/hackles display.
My main problem is that they're coming to stay for a week over Christmas and there is no way that I can put up with a week of this behaviour so what can I do to stop it?
She's such a nice, loving dog to everybody else and has never growled or barked before so what is it about this one man? As stupid as it sounds, he's a smoker and we don't hang around with any other smokers- could it be something to do with the tabacco smell that she doesn't like? Meika absolutely loves him and throws herself all over him, and he isn't nasty to them at all. He's actually quite upset that Molly doesn't like him. Maybe I've done something to make it worse and time out isn't the right thing to do but I've never had to deal with an agressive dog before, especially one who loves every person they have ever met except for this one man!
