This my second year Hunting and I have a trained gsp that's 2 1/2 years old. I've taken him Hunting and I wanted to know a lot of times he goes on point but no bird.. Is he just picking up old scent?? And he is patient on his point but sometimes when he runs by and doesn't pick up scent on a bird in a bush that I walk by and I end up flushing them on accident Lol.. Is that normal?does that just have to do with wind? And these Damn birds just don't hold they flush so fast.. This is in Socal by the way. Just want to get opinions from other dog handlers. This is my 3rd hunt with him. Will he improve the more I go out and hunt?
