I'm hoping for some advice on what to do with our GSD, Cynder. She's 8 months old and she seems to have a fear response when she sees a person she doesn't know, adult or child, and dogs. She starts barking, her hackles raise, but then if I'm there and encourage her to approach the person, she pees all over the place. I take her to work with me once a week, in the hope that she will eventually make a good therapy dog. I work in a nursing home as a speech therapist. She's great with the residents and staff members, however if an unfamiliar person shows up, like a visitor, she will let out a low bark, not real loud, just enough to hear and she'll back away. She's very sweet and loves attention and to be petted. She was exposed to the nursing home since she was 7 weeks old, has been around a lot of people, we have taken her to a dog park to socialize her, as well as my friends who has a 9 month GSD as well as other dogs in her home. I thought I had her pretty well socialized but I guess not? Or is this a puppy stage of stranger anxiety?
