My dog bites aggressively and my family won't do anything
We bought my 3 year old jack russel believing she was a sweet dog and I love her very much but towards people that come to our home she is very aggressive. I am a very protective person and can't stand it when the dog bites people but the rest of my family just let it go and don't take any actions. I am not sure if my dog bites because she is scared or possesive. I want and need her to stop being aggressive towards our guests. I am not always home when this happens and my family won't commit to train her, How can I get my dog to stop biting with only me training her?
