Hi my one year old female Labrador doesn't like men, not all men , she has no issues with the men in the family that have always been around but it's 50/50 with any males she encounters , when she has decided she dislikes them she barks at them constantly and just appears to be scared I know it's not aggressive but it does sound that way. she doesn't come around to them either I usually have to remove her from the situation as she is very stressed , one example was my uncle visiting from out of town she freaked out and he tried to calm her but when he spoke she was even worse!.
I really don't know what to do with her to help her get past t as I have no idea what it stems from as we have had her since the day she was born , we have her mum who had a litter and there all in the family, one of the other puppies is same with new people which is strange to me as her mum loves everyone! And so does there dad ( my friends dog )
