Scissoring is by far the best method, particularly as the coat grows out because it does not leave little frizzy ends that are often seen with clipper cuts. It can be much more expensive at commercial groomers which could be why so many owners settle for the clipper cuts. Scissoring gives a much cleaner, longer-lasting finish, when done by someone who knows how IMO. Besides if your breeder doesn't have large enough clippers then, perhaps, she has never performed a clippered puppy cut before. Why not give her a chance with her scissors - whatever happens, don't worry, your handsome little man's hair will grow again
