20 dogs is too many for one person. For 6 winters i trained with and shot for a friend who is considered to be one of the top , if not the top, young dog pro in the country. He had an assistant trainer and 6 bird boys. The truck was split about 50/50 between the two .... And 2 flyers per week is pretty standard. Look @Lardys truck -- about 20 dogs and split between Pat, Ray & Mike
