Had some conflicting opinion when you start a pup to count. I attended a FT when my pup was around 4 1/2 mos and told some of the people I talked to that I have started doubles w/ my pup. They were suprised and told me to stop before I ruin my pup. I did not stop but lessen my multiple marks to at least twice a week instead of 4-5 a week. Just recently, I found out from my pro that multiple marks or at least doubles were good to train your pup to count even as earlier than 4 mos. Just curious how many people in RTF trains early w/ their pup on how to count?
