i missed this thread, but so glad Benny is doing good. we learn things as we go along, and the way tracks are laid is so important. smells do confuse them being close to trees, fences, buildings etc. but as they get better they learn to detect the right tracks and smells.
Sam likes to follow other peoples tracks the best, more exciting. the biggest thing is learning to trust the dog once he knows whats he's doing. a few times i had forgot how i laid the track, and Sam was right every time, you learn to read them well..........
