So I have a half fiest and half cur dog. He isn't even a year yet, but will tree a squirrel if it is seen, will even timber it a little when it starts skipping tree. Now I have seen him run a tree but never bark on tree that has a squirrel in it, I don't think he has figured out the whole nose and what it is used for thing. I have praised him shook trees shoot squirrels, taken him with other dogs still cant get him to open up with just smell and not visual?? any advice, or just play it out and hope it comes?
