OK, here is what happened. The first series was a walk up. The memory bird was about 35-40 yds and the go bird was about 55-60yds, to the right of the memory bird. The blind was about 40-45yds, to the left. She did fine on the go bird. I lined her up and sent her(no hand down nor did I know where the blind was. Did not know that series had a blind.) She towards where the blind would be placed but did not start a hunt there. She blew past the blind and circled around the memory bird starting to go back to the go bird, thinking there was another. That is when I started to handle her to the memory bird. Pretty much the same situation on the water series.
Can you explain selection drills to me? I never heard of them.
I can't explain selection drills as I've never heard of them either. I can explain primary, secondary, and ideal selection but don't think that will help you with a double.
Checking down on a short bird after going long is a skill that you need to train for. In training, how often do you run a long go bird and short memory bird?
Also, many folks use ques to help their dogs remember a bird when they may be a bit fuzzy. What ques do you use at the line before sending the dog.
I put a hand down to send on the go bird and also on the long bird that I usually pick up last (I use secondary selection most of the time) in a triple, but I don't put the hand down for the short bird. That is a cue to the dog that we are going short. After the dog returns with the go bird and we line up for the short memory bird, I'll get the dog focused and tell the dog "easy" in a soft voice before taking the bird from the dog. That is a cue to the dog that we are going short. When sending for the short bird, I'll send in a soft voice. That is a cue to the dog that we are going short.
There are many marking setups you can run to enhance short bird marking. I recommend you check out Retrievers ONLINE and look at the index of articles for ideas. In general, work on long go birds with a short memory bird. You can also run a long blind before a short mark.
