This is a real question..
Is it really a matter of locking onto "SOMTHING" on the horizon,,, or is it more a matter of agood handler setting his dog properly at the line, and training or conditioning the dog to go as sent?
I will line the dog with good physical placement at the line (Dogs spine in line with bird) and send the dog.
The dogs runs straight as sent due to many reps that have included handeling to keep him on line. He eventually runs dead straight, cause he doesnt really like to be handeled.
Is it MORE a matter of conditioning and reps?
