So the last couple of nights I have been throwing water marks for 7.5 month old pup. I put him on a place and go out to throw water mark so I can extend his range. I wish I had another person to throw marks for me, but this is not always available. After throwing the mark, I return to him at his place at heal/sit and give him fetch command and he will take off aggressively about 6 -10 feet and then turn around and look at me as if needing more direction. He is fine if I give him a hand direction or back command from the location out 6-10 feet, but I don't get the stopping and turning back to me for direction. I have not seen this behavior on any land marks that I can recall.
It may have happen once or twice if I have had someone throwing water marks for us in the distance, but I really see it after I throw one and then send him from a mark I have thrown from a distance.
Dog is currently doing force to pile drills in the morning, as that is the progression of where we are in his training after basic obedience, FF, CC, and three hand casting.
I am not sure if I have provided enough info here so if more info is needed let me know and I can expound and give more background.
