Hello! I have an 11 week old puppy (bubby). This is my first golden and I come from bully breed rescue in the past. We picked out our boy and have noticed that he has fear around meeting new people and meeting/socializing with dogs. He seems more comfortable with dogs his size or smaller, but still unsure. He is cautious when approached. He will drop the tail (sometimes between his legs) and sometimes pee. With larger dogs, he will sometimes show his teeth and back up or growl and back up. With people he sometimes runs up and is fine, other times he is fearful and backs away. We have been carrying treats and having people give him a treat when meeting him and that seems to be working some. We start puppy kindergarten today and I am nervous. Has anyone has this issue? How did you work through it? I had a very reactive dog before him and I do not want to repeat that. Please help.
