I was told by a Finnish Spitz breeder and Elkhound owner that these breeds need the lead on at 6 weeks, as they can fight very determinedly, so the sooner they are used to the lead the better. I have never had any trouble with any of mine except for initial resistence, but having seen a p-up I bred allowed to get away with not wanting to walk on lead, and how embarrasing it is at training class where she refuses to walk, and of course being a woden floor can happily slide along rather than have to walk, then I think it does depoend on how stubborn/independant the bred is.
My methos has always bento attach lead, and let pup walk about with me holding the lead, and never allowing any pressure until pup seems happy, then I will encourage with voice and treats for pup to go where I wish to go, and then give the odd little tug and then release to get them to move my way if attracting attention doesn't do the trick. this way they learn that they will have to complu, so better co-operate when called. I do this all at home in the garden, as the experience of traffic and lead being new will be more stressful. At least when used to thelead walking along the stret won't be so scary. Of course I live in the city and don't drive, so my first walks outside the house are straight on a busy road.
