What's the best way to break a dog from runnin deer. I know lots of people use trainig or shock collars. But what do you do when they're out of sight. You really don't know if he's runnin by scent or sight or if he's done runnin a deer and back to huntin squirrels. The past 2 times my dog has done good the first 45 min - 1hr or so. Going out to 150yds or so and checkin back in. Then he's gone. Tracked him 1.5 mile this mornin before I got to him. I didn't scold cause he's done forgot about what he done. I don't know that's what got him gone so quick but what else could it be. I'm still learnig as he is to. Thanks for any suggestions.
