I just think that these animals could be used for anything from being trained to fight or to be used as bait, plus there is no need to take such a risk with your pet if you can no longer keep it. There a places where you can take your pet free of charge dogs trust, Batttersea dog and cat home, Rspca etc
I was just shocked when I saw a advert for a (family pet 5 years old free to good home) as owner can no longer keep it for whatever reasons. I remember reading that a dog was found with it's mouth taped closed and legs tied after it's owner placed a similar add and the police suspected that this dog was used as bait to train fighting dogs
