Jax is a rescue and was found a couple towns over with no collar. She was very thin, very fearful, and very high energy. When we adopted her in 2012, she was fear-aggressive. She had no social skills and had to be taught manners from the ground up. She is 75 pounds and she is my petite little freight train! She got better with people, and with proper introduction, is wonderful. With other dogs, she was horrible. So we brought in a couple of shepherd puppies to introduce her to dogs. She is now leash trained, muzzle-trained (hates the vet), pack trained (carries water bottles), and is our guardian here. We love her! Jax is naturally protective and is hyper sensitive to my feelings and moods and reacts accordingly.  She still has issues that we are working with and I'm hoping to find help for her on this site.
