I have "inherited" a two year old unspayed female pitbull. She has repeatedly attacked my older dog. Will spaying her help end the aggression and the attacks. The vet bills are starting to rack up. I have them seperated now, but I don't want to live like this, with gates up all over my house and to have the animals seperated. I would like to be able to have them in the same room or be able to take them on walks together. Right now this just is not an option. Any advice or help would be appreciated. Thanks!
