I always liken dogs to children. I never met a bad child (dog), only bad parents (owners). Dogs, like children, are intelligent, inquisitive and need instruction and guidelines. A dog that plays up is usually either bored, mistreated or both. Same with children, too, I guess.
We used to have a dog. Adopted it as a puppy... a mutt. As it grew it started getting aggressive towards the wife and kids. Kids I can see, because the girls would show fear in front of it when it started snarling at them.
It usually behaved when I was with it- although, on occasion it would act up with me at home- learnt not to try jogging when I was on a walk with it... drew blood from my leg several times when I would try to jog... would bite my legs. Otherwise fine around me- although towards the end- it was getting more of a challenge for me to manage it too.
Finally my wife had to record a video of it when I was away from home to see how out of control it would be. It wasn't abused/mistreated- got as much attention as it could from family. Perhaps it was a training issue- we took it to training classes- I personally spent over an hour each day training it- and family got involved too - so it would learn to accept commands from them.
Between training classes/ personal trainers/ me working with it for hours... it was given all the chance it could... it was just an aggressive dog. It was determined to be dominant dog- we did give it up for adoption finally (didn't trust it around the kids).
A man who had experience with aggressive dogs took it from us. (or at least said he did) - he ended up putting it to sleep when he couldn't control it.
I'm sorry- but that dog was never mistreated- it was given lots of instruction- from me personally, but also professionals. It was given guidelines. It was just a bad dog.
Dogs are like people- some of them are more aggressive than others. This one, perhaps it could have been controlled by the right person. (same with bad people) - but it was a bad apple. I loved it, was sad to give it up- despite it biting me on occasion- but it was a bad dog.
Too many good dogs in shelters with no owners- this one was not one.
* Did DNA test done on it- found out it was a cross of four breeds Pitt Bull (American Stafford)/American Bulldog/Lhaso Apso... forget fourth dog came back on the dna test... was another yappy rat dog. So many bloody Pitt Bulls in South Carolina probably can't trust mutts. It's the Pitt and Rat dog cross that is dangerous too... frequently those crosses result in aggressive dogs- that are also powerful... pitts themselves, can be aggressive if not trained properly- but usually are sweet and lack the attitude.

). However, he is well behaved too. I rarely have him on a lead when out. He does get interested by others that are out and about but I shout him and he comes back leaving them alone. Only trouble I get with him is he occasionally pisses and ****s inside (
) which I think is a disobedience thing, and he stands up for his self when being told off the little ****er
