Deff. no pro here, and I didn't see much I would worry about as far as the line, but if this is something you are genuinely concerned about, place the bird on the line at the point of "flair" and work it back from there gradually. She should run over the each additional progression. Personally I think this would back track you to sight blinds until she gets to the full distance. She looks to be progessing great for a year old pup. Personally wouldn't worry about it.
