Adult dogs in shelter are usually there for a reason. I wager someone had the same problem you did. The first thing I would tell you is that a tired dog is a usually a better behaved dog. I would keep both dogs seperate, and I would start both of them over from the very beggining, as if they were pups. You should start crate training both these dogs and put both on a NILIF program. http://k9deb.com/nilif.htm

I think you can improve the behaviors, but I doubt if you will wipe them out completely. Make sure you keep children away from the dogs too.
To sum it up, start training them from the ground up and keep the adult well exersiced and tired

opps double post

True, they run stray and people won't pay to get them back; they run stray and are unaltered and people get mad when their dogs get pregnant; people decide they no longer want them; people die; marriages split and neither want them; they no longer match the furniture; they require medical care and people won't pay; people expect them to train themselves; they get left outside alone unattended and bark due to boredom and neighbours complain; all kinds of "reasons".

yes that is true, it is also true that 50% of adult dogs in shelters came from shelters, and because of all those reasons one has to be VERY careful when it comes to taking an adult dog from a shelter.

Where did you get those stats? I'd question that, and how they are compiled - and by whom, and I would probably still disagree. <img src="/ubbthreads/images/graemlins/laugh.gif" alt="" /> And I would also NOT agree you have to be VERY careful either, no more than in most other ways of acquiring a companion; and acually LESS than some of the common ways in my experience.

Gotta like the honesty <img src="/ubbthreads/images/graemlins/smile.gif" alt="" />
Here is a link to the study

I think it is important that people go into adult rescue dogs with their eyes wide open, even the reason you suggest for relinquishment indicates that the dogs will have experienced their formative period in poor environments.

One thing I've noticed. If Thomas quotes a stat he is going to be able to back it up.

To help your problems:

Terriers are high energy animals. They require play and lots of it. Run him around.

Just like a dog who has never been attacked by another dog, your dog was not afraid of people, until moron kicked him. Once a dog is attacked by another dog it may become dog agressive. It remembers being attacked and becomes more defensive. Same with people, I would assume. If someone beat you badly you may become more suspicous and willing to use force againce a percieved threat faster.

IMHO, to accelerate a 22 lb object over several feet takes a lot of energy. What this person did was out of line. If someone did that to one of my dogs for any reason other than a bite (which my dogs would not do) I would be in violent mood.

Others here may have more information on this, Ed probably has an article on it. Use the google search or the TOC to find it. I would start with that problem.

There are very few dogs that are a total loss genetically.

Crating. Food Control (only you feeding him at certian times), are a start. Correcting agression is not something I have dealt with but I'm sure people here have.

As for rescue animals I have gotten dogs from many bizzare places, hippy neighbors, GSD rescue and have had no problems. The GSD is not K-9 material or the like but is intelligent and has the proper drives to make a good pet and a SR dog. Excellent animal. In the pound because some moron didn't want to crate him. Dog ate the house, surprise. 99% of dog problems are people induced.

Good luck on fixing your dog. Control over its environment is a good place to start. Treat it like a puppy and start over from the crate.

I would say that is in the ballpark. The problem with adult shelter animals is that "uninducing" the problems is not something the average person can easily do on their own.
