The Reward System! I find it alot eiser to reward then punish!
example: Instead of being mean and yelling at him/her when she pee's in the house scold him/her mildly with a "NO" and
when she goes outside reward him/her with a treat or a warm loving reward!
lots of people say that crate training is the method to sucess but really to me it works all the same!
a good pet training site!
