I will try to help give enough info to help with answers, so here goes. I am using the lardy method with my dog. We are in the middle of transition as far as drill work and field work with the exception of the following, a week before a junior test I let my son handle my dog and we ran singles. After the test I continued with drill work, and kept on running singles from multiple guns for about one month now. Today I set up an "easy" double as a sort of fun run to keep her spirit up. The memory bird was 50 yds and the go was 70, in light cover,seperated by 90 to 100 degrees, almost visible from the line with no apriciable wind. The go bird was very nice, back at the line she appeared to have the memory dialled in, but when released she missed it twenty feet and never slowed down, she is a fast dog and I was surprised by her action. While I was watching wondering what happend she hunted her heart out, out to about two hundred yards, then hunted back in to about 100 yds, sat and looked for direction. It wasn't a pop but a " I just can't find it, can you help?" I handled her to the bird. I had another winger loaded so i threw a 30 yd memory, heeled 90 degrees and hand threw a go bird. Again it was flawless. Then came the memory and she locked on, I released her and she didn't have a clue, she hunted around and eventually found the bird. Before I went to a strict diet of singles she was doing doubles well enought that I had started teaching triples. But, after a month of singles it is like day one ! There seems to be a fair number of proponents of throwing mostly singles. Did I not give her enough doubles before going to mostly singles. I was somewhat surprised that she could regress so quickly from where she was. From what she showed me today I need to go back and teach simple doubles. Anyone ever been here ? Any help would be appreciated. thank you.
