Okay --
-- so it sounds like little Tuco is being what he is -- a pit bull.
Pit bulls, through their breeding, have dog-aggressive traits -- this is more the norm than the exception.
Little Tuco was rescued from the streets by Kristen -- that is a wonderful thing -- and I am sure he was as handsome as he is now -- making his rescue and adoption quite attractive.
However, the dog aggression that pit bulls have is often more than people originally bargained for. It is important to know that dog aggression is not the same as human aggression -- and while dog aggression should be managed, human aggression in the breed is unacceptable.
So, for Tuco, it sounds like he's quite attached to his little sister, and that leaving his home will be hard on him --
-- the odds are against him -- he is an adult, he is a pit bull, and he needs a home --
-- can you help break the path this boy is going down? Will you accept him for his breed, researching dog aggression, specifically towards pit bulls, also?
If so, fill out an adoption application above!
