Not trying to teach my granny to suck eggs, but if I may a little suggestion regarding the pup. Sometimes it is not possible for a dog to track with ground scent, and with the pointer in the breeding it might be an idea to use the wind and teach the dog to air scent also. It really is not difficult, all it means when you send the pup out for a find and retrieve as you did in the video, cast him down wind of the retrieve and work him into the wind. The rest he will do himself.
