How many people run their dogs on empty stomachs on the day of a trial and do one feeding after the last series? I read an article by Lardy quite some time ago that was about a study that Purina did with sled dogs which showed they performed better on empty stomachs. Last summer I only ran 3 derbies and would feed the night before. I didn't feed him until we got back home after the trials. I liked the results. Curious what other people are doing.
