Oops! I see now that I posted this in the wrong place, I think. I didn't see before that there is a training forum...Sorry.
I am sure that the answer to that question is "clueless human" which is why I am here looking for some quick help. Let me fill you in. By the way this is my first post here.
We adopted a two (or more) year old dog (they told us he was two, but they didn't actually know his age; they just guessed) and he has been a wonderful companion so far. No aggression, no pottying in the house, minimal barking. A truly lovely little guy that I wouldn't trade for the world, but the problem is he absolutely refuses to be trained. I'm not sure how his past owners managed to house train him because I have read a couple dog training books and I tried for about a week or so to teach him to sit and he never did catch on. Maybe that isn't long enough for an adult dog, I'm not sure. The method I was trying to use was to wait until he sat on his own and then say, "Sit," as he's doing it and then reward him in the hopes that he would associate the word with the action. Well, he gained weight, but that's about all. I have had a couple other dogs in my life and both were very easy to teach, but they were also puppies, which I guess makes a big difference. I trained them using the old "push the dog into the right position and then praise" technique, which I have read in the books isn't good (I didn't have the books back then).
The training issue would not even be a big deal except when we come to the furniture. He has decided that he loves sleeping on our couch, which we don't want him to do. We made the mistake of tolerating it at first, but now we don't want him up there, so everytime we catch him up there we order him to get, "Down!" and then pull him off by his collar.
You would think that after weeks and weeks of doing this that he would begin to understand what down means, but he never does. You come into the room, see him on the couch and say, "Down!" and he just lays there until you force him off. We now barricade the sofa anytime we're not there because he gets on it anytime he gets the chance. It gets annoying after a while having to take the barricade off and put it on.
Now we do allow him to sleep on a chair in the same room. Is this too confusing for him? Do we need to make all furniture off-limits? He is not allowed on the beds and I have only caught him on one twice and he seemed to learn that those were not for him...or at least I haven't caught him on them since.
The only reason why I haven't bought him his own dog bed is that we live in a small condo that is only about 800sf and every bit of space is used up. I could get him one and put it in the middle of the living room, but it would be very in the way and I'm not sure he would like sleeping there.
It is getting to the point now where I am considering just giving up and letting him have the couch, as the only thing he is learning is to look nervous when I come into the room as I now spend half my life scolding him. I don't want to be mean to him and I feel horrible at the idea that I could be damaging my relationship with my dog without teaching him anything.
I hope I don't sound like too much of an idiot. I actually have read a couple dog training books, though it was a year or more ago now and I guess I obviously did not learn much from them.
Any suggestions would be appreciated.
