I have one right now I am working on swimby with that is just giving me fits. He was at the point of having had the first over pile taught and had made a successful swim by to the exit at the opposite end of the pond. Thought I was ready to teach the opposite over and exit. I had to take a couple days off due to weather. When I got back at it, the day was rainy and the water temp 58. I went ahead with those conditions and went to review what had been taught to that point before intro of the new over pile. Dog goes to back pile fine, will cast to the previous taught over fine, but then refused to reenter water from the over pile for the swimby. I tossed a bumper out in front of him and he will go to that but then he insists on coming in to the near bank. I try to stop him but he will not stop. When he gets to the bank I give a back trying to get him back in the water. He wont go unless I take the bumper and toss it back over his shoulder. He keeps trying to run the bank. It's like this all the way down to the exit. I have tried walking him back to the over pile and sit him, I walk down to the exit and call him to me but he refuses to reenter off that over pile, he wants to cheat and run the bank. When he does I whistle sit him and give an over to get back in the water. Nope, he wont have any part of that. I have been stuck like this for last two sessions. During the last session yesterday I ran down to the exit as he swam to the over pile. I twirled a bumper after he picked the bumper off the over pile and called him to me to entice his reentry off the bank and swim down the channel to me. He did comply by my doing that for the last three bumpers.
I can keep running down to the exit and twirl a bumper to entice him to reenter at the over. I know he knows what I want, he has already did a successful swimby to the exit from that over pile.
The water yesterday was 60 and it should be at least that again today. My question is would you use force at this point or keep using attrition?
