If I do the blind first, I try not to line him to the mark but let him come in and place himself. I cue him "where's your mark" IMO
Do you use holding blinds in the field to hide your launchers? If distances are reasonable then both you and the dog should be able to pick them out. You might consider going to white stickmen for a while and run lots
Are you using ducks?
Drakehaven, That almost went over my head. I haven't thought about spot bowling in many, many years.
I apologize if this over simplifying. If it's a left healing dog, point your left foot towards the memory bird right after it's thrown. When the dog returns he will be more or less lined up. I would run more singles so the dog grows confidence in his marking, than run some multiples. After that run about 80/20 singles to multiples. But after that's said you still need to learn to mark as well.
Hmm I'd set him up for remote marking and sends; if your not beside him to screw him up, he should go to where he knows the bird is. Bring a nice chair to sit in why he does the work Problem Solved ;)
Still in training I wouldn't mess with him at the line, I'd send him; if he goes to the wrong place-or takes the wrong line (on a mark), I'd whistle sit him NO nick, Get in here!!! Get your mark (Resend), Dog learns it's his responsibility to get to the mark, the correct way. Regardless if handler sent him in the wrong direction, wrong line etc. Marks are his job, lining up correctly for marks is part of that job...Blinds are another matter entirely; probably why we have cues to tell a dog when it's his job or ours (Mark) (Dead Bird) (Leave it) etc.
If I throw multples, I know my pup has the mark when she looks over her shoulder at the memory mark on the way back in, She then backs her self into position, I take the bird or bummper from her mouth, I then confirm her mark with "that's right girl , that's your bird" and send her name. Big send if the bird is WAY out or little send if the bird is easy.
Have fun with it.
