Because Katie is a rescued/adopted dog, I am unsure of her past... but I know that she can't stand other dogs. She starts barking, pacing, and whining and eventually charges at any dog that barks at her or gets too close to her. At first I thought it was only small dogs, but she did it to a lab the other night when he sniffed her a little too much, and she has started snapping at my parents' dog from time to time (unprovoked). She will go for the neck and charge so hard she is jumping in the air as I hold her back by her harness. It has gotten to the point that my family wants me to give Katie up to a rescue, because they are afraid of her hurting someone or a dog. She hasn't really tried to bite a person yet, aside from playful nips for attention, but I haven't had her around kids much, so I worry about how she would be with them as well. I don't want to give up my baby... She is 5, and I just wonder if there is any way for her to overcome her aggression at that age, or even work on it. Do any of you have advice, suggestions, or experiences you could share to help me out? Thanks in advance. I appreciate it so much!
