My year old black male has been doing very well with his training. He has seemed to move pretty quick. This is the first dog that I have trained. He is doing great with the land t, double t, and even some simple pattern blind. He lines great. When he here the cue "dead bird" he zones in on his picture and for the most part runs a straight line. My problem is starting him out on water. He is a very solid water marking dog. He attacks the water very well. We have started swim by just as shown by Chris Akin on DUCK DOG BASICS. Something went wrong here. I can not get him to line up correctly. He refuses to point his head toward the water on the "dead bird" cue. He aligns everything else correctly. What can i do to get him to zone in on water like he does on land? Thanks in advance.
