oh the poor baby, I am glad you got the other one out of there. But are you SURE he is fighting them? Sasha has scabs one her but that is from a allergic reaction to plastic. The Scabs were really bad for a little while, she looked roughed up too. But also if this guy hit her in front of you, you never know he might be the one that makes those marks. he might hit him with other things. It is really a hard situation. you are a great person for trying to help. I wish the would do something for this dog (not kill it) if it is adoptable.good luck and keep us updated.
