For decades now, I have adopted "troublesome" dogs. Usually large scent hounds that some halfwit purchased, who had no idea how to properly train and work such animals. Generally with focused training I have been able to turn the dogs into productive members of society. This is not a project for the inept.
I grew up around such dogs. When I was a child my grandparents took care of me during the day, and my grandfather maintained a pack of black & tan Coonhounds, and a pack of beagles. He *never* let those dogs inside the house, though he was very kind and caring and attentive to the animals. He used them for their purpose, and spent a lot of time and effort training them and breeding them to his requirements.
I have a 150lb Bloodhound sleeping on my feet as I type this. A neighbor got the cute little male puppy. She was a first-time dog owner, and a single Mom of two toddlers. Living in a two story home with wooden floors. She came to me when the dog was about 1.5 years old begging me to take the dog - it was knocking over the children, eating the food off their dinner table, dancing on the kitchen counters and furniture, and resource-guarding. And was about 120 lbs and still growing. It took me months of work to turn him into a perfect gentleman (for a Bloodhound(*)). This dog was well on his way to being destroyed, but now he's both a great working dog, and a fine companion for my life. I use him for search and rescue work, and one day he arguably saved a few dozen lives when he alerted to a fire in the village in our senior housing apartment building as I was walking him nearby. After I called it in, we went in and knocked down the fire with a water extinguisher before the fire truck managed to arrive from the station down the street. Good dog.
(*) Some of the scent hounds are the hardest dogs to "train" to perform traditional tasks, they aren't quite like regular dogs. A "smart" dog may be able to learn a new behaviour with a handful of repetitions. These hounds may take hundreds and hundreds of trials, and constant reinforcement will be required ongoing.
