OK when I say retarded I dont mean really dumb I mean mentelly retarded .when we got this dog it somhow seemed like thier was something wierd about this dog not like it was a bused but we have come to the conclusion that we think it is slow . I dont know if you can have a retarded dog but poeple have retarded babys is it possible in animals ? she doesnt learn anything we have two other dogs that picked up things quickly but she picks up nothing she doesnt seem to understand basic trianing that most dogs should and she still has accidents if we are not watching her every minute of everyday . However she is very very sweet one of our sweetest dogs but she is just not the brightest dogs and she doesnt seem reguluar stupid she seems really stupid it is so hard trianing her and she doesnt listen ever . she is a sweet dog but we kindve think she is slow .Also alot of retarded poeple are very sweet . So I dont know this was a group conclusion of all of us who own the dog but do you think we are correct is this possible ?

Of course it's possible. Or it's just a dumb dog. If it really matters, ask your vet. We had a cat with brain damage (traumatic birth) and sometimes I swear my current dog is autistic.
Translation for Allistalla: ur spillin ess retadred.
If you're having that much of a problem training your dog, just bring him to a professional trainer instead of calling him retarded. The person training the dog has to be good at training as well. Maybe you're not doing such a good job training him. And even if he learns at a slower pace than your other dogs, that still doesn't mean he's retarded.
And it is a fact that sometimes its not the dog that has the problem, but the trainer just isn't good at training. Thats what I was saying. Never did I ever say that I hate or laugh at the mentally disabled. You've completely turned what I said around. Its dumb to just chalk it up to say that your dog is retarded just because he takes a longer time learning. Thats where you're the ass, asshole!
As much as I still really want you to understand what I was trying to say, I'm not gonna pick at this anymore. I'm sorry if my first post appeared as though I was attacking you. Maybe somewhere I did misunderstand you, but I think you've misunderstood me too. It would be pointless for me to argue with someone online, especially when I don't even know you, so... moving on.
Pet psychosis has even been documented and this can be linked to aggression.
But mental retardation if its the case is unlikely to present with aggression in a dog.
In any case, it's a dog. It doesn't have to go to school, get a job and work, or go to college. It doesn't have any real responsibilities, so it's nothing to worry about.
Ironically, if your dog is retarded she may be more evolved. Not saying its a superior model but that domestication has been documented to lead to reductions in an animals intelligence, because it doesn't need it since we take care of it and as all abilities use up energy natural selection gradually drops anything a species doesn't need.
