I didn't read this site, but, there seems to be a lot of information on agressiveness. Here's the link. There was a site once that I thought was helpful, and, I'm trying to find it!

I will make a couple of comments, though, after having read the other's remarks. I definitely agree with NEVER using the crate for punishment. You mentioned telling him no and then putting him in the crate. And, I don't think it's a great idea to put everything in the crate with him, either. The crate is only supposed to be big enough for the puppy to lay down, stand up, and, turn around. If you're having to put him in there for more then 4 hours at a time, they have those cage water bottles. BUt, I, personally wouldn't put food and a place to potty. Unless you're not using the crate to potty train. And, I know I only leave one or two nearly indestructable toys in my puppy's crate with him. Like a Kong or something. Anything that can be chewed on, but, not chewed up, and, not too many. And, if the puppy is sweet to your mom, but, not to you, maybe you could try to figure out what your mother is doing differently. Is she being more consistent with him or something? That's just strange that he's only being mean to you. Have you tried him with other people? I didn't read, and, please don't take offense to this....but, are you a guy? How old are you? How many others are in the home and how is he with them? Are you the only one that he is agressive with? Maybe he has issues with men and not women. How big is the dog? (I hadn't looked at the photo yet, and, didn't know how recent it was anyway) How long has he been agressive to you and do you know if there's anything about you that has changed since the agressiveness started? I'm sorry for all the questions, but, I'd hate to see this dog grow big and strong and still be that agressive with you. That would suck. Anyway, train the heck out of him, and, never use physical force with him, I think that would only make things worse. Fighting a fighter is counter productive. Kill him with kindness, man. Good luck, and, keep us posted.
