Hello everyone, thanks for taking the time to read my post. I have a 1.5 year old border collie/blue heeler/Australian Shepard mix (half Border Collie, quarter others). She is very social, I have her decently trained with basic commands and tricks. I am have big issues with her in introductions to new people. She seems very excited to meet them only to become aggressive, (or defensive..) when they start to pat or talk to her. I believe this may be a socialisation issue as I live in the country, and she doesn't get exposed to people on the daily. I have been trying to get her out as much as possible having positive encounters with people but she continues to freak out about 50% of the time at people, showing teeth and barking for no apparent reason. How do I get my dog to trust strangers and not freak out in situations like this. How do I install confidence in my dog to handle this situations. She only reacts this way to men which I dont understand. I am a man. Shes never been traumatised or beatin. My folks are starting to think we should get rid of her. Please help. Also my parents do have some sheep that I have had her around a few times for fun.
