How do you convince your parents to let you have another dog I am 15 and have 2 dogs?

Oh hi! I've had that situation before! It's horrible! First of all show you are caring and loving to your 2 dogs already. But before nagging them take EXTRA good care of them show you are passionate about dogs and that you are a responsible young person. Then sit them down with you and say out loud all what you feel about the dogs, the whole buisness ..... Hope I helped :)
