Sorry, I wasn't clear either. Nothing said has upset me. However, it would appear I have misunderstood some things due to no knowing you and your approach/sense of humour, etc, as well as the lack of tone that comes with written communication.
The offer of this house (which I do pay rent for, I'm not just free-loading, before anyone jumps to that conclusion) is something I am extremely grateful for, as at the time it was likely that I would have to move back home, and I certainently wouldn't have been able to take Rusty with me. Back home was not an option, actually, maybe I should have been an outside-only daughter, for everyone's sake, I don't really play friendly with family (or anyone) for ongoing periods of time. If I hadn't accepted the house, he would still be living with my parents, outdoors only (not even the laundry, but still plenty of shelter), and that would still be an issue from the perspective of dogs should be inside, however, those neighbours never noticed and/or complained about the barking, so I probably wouldn't be asking for help.
I don't think my parents discussed wether dogs could come inside or not at the time they were getting married. There was no talk of ever having a dog until I was old enough to start begging for one, and it wasn't even considered until I was old enough to take most of the responsibility for him. I would love to see the divorce papers after a 15+ year marriage saying that one party wouldn't let the dog come inside as the sole reason for seperation!
I don't really understand the point about Rusty dieing for my mum, and her remote kindness. Not in a passive aggressive "what's your point?" style, as in I really don't understand what you are trying to say.
Thank you for your honest opinion about him being happier inside. It may very well be true, I don't know. I don't know what he is thinking, and if I could, finding out if he would like to come inside would not be my first priority, but I'm sure we would get there eventually. However, I think I would be happier in a much larger house, with a pool (I'd even let Rusty use it!), and a bigger account balance. However, at this point in time, that is not going to happen, so I will deal with what I have. At this point in time, Rusty will not be coming inside, so he will have to deal with what he has, and deal with all he has known for the past 7 years.
If I had a pig, I am pretty comfortable to say that the pig would be an outside pig, regardless of my living situations. I don't have a problem with pigs, I've never really had anything to do with them, but then I hadn't had a lot to do with dogs until 7 years ago either. Pigs, horses, goats, geese, sheep, your basic barn-yard animals would all be outdoor animals. They would not be in my house, let alone my bedroom or bed. No chair needed (although it will be if we are adding mice, rats, snakes and/or lizards to that mix), just four walls seperating me from them when I choose.
I have the "waggy tails and bottoms, beaming doggy grins and devoted eyes", it is just outside the back door (as long as there aren't any dogs, strangers, etc. around). I don't think the inside pet bane that comes with the house is mess-related, it is a standard based for all pets, that pets belong outside. I may not agree with it in all cases, I understand it, and I respect it, at least until such time that it is my house to make those calls with.
In theory, perhaps Mum shouldn't have ever allowed a dog. If it was completely up to her, we wouldn't have, not because she hates them, but because she didn't have a desire to have a dog like I did. Then Rusty would possibly still be sitting at the RSPCA, he was a long-term resident when we adopted him, and while his aggression wasn't showing, his fear was, which turned other people off him, and, in retrospect, should have done so for us, his issues are really a bit too much for first-time dog owners to handle (at least without professional help, which was never considered until recently), so I'm hoping that he thinks a nice big back-yard, a couple of comfy beds, toys, plenty of food, regular walks and plenty of love is enough, and he isn't spending his life lusting after that little bit more he might have elsewhere.
