I am an avid clicker trainer and all my dogs are trained using one. I am also working on expanding my knowledge as a Trainer. I have a Golden Retriever that get growly face at other dogs. However, it is not all the time. She does not lunge at other dogs. She sometimes even will greet them with mutual sniffing. Then go into attack mode. Other times she just instantly loves the other dog.
I know there is a way to resolve this using the clicker, but I want to avoid accidently clicking the aggressive behavior. Even if she is just thinking about it. Any ideas besides the obvious having her look at me when meeting a dog. I would like her to learn appropriate social behavior and to interact with other dogs. I do know she has SERIOUS issues with dogs acting at all dominent around her (ie putting their feet on her, head over body). Some of it seems dominance based and some seems almost fear based. She has been attacked by other dogs at least twice. Once by her mother when she went for a visit around 5 months old and once at PetSmart by a lab. She loves Rottweilers and Pit Bulls. She especially find puppy behavior insulent. She usually gives them the "evil eye". A sideways glance and gets stiff. She looks very much like Caesar Millan pretending to be an aggressive dog. lol

Thanks for any ideas you may have,
Kaos
