Diesel also has white hairs. He has a few just under his bottom lip (you see them just very faint) and he also has small white patches on all four feet between his pads.

 

I have seen many pedigreed black labs with white hair on their toes, a few small white spots on their chests. HK has two areas, about 4-5 hairs each, that are white between her right eye and ear flap.

 

Mambo has them two and he will be 2 in March. He now looks like Rome and Romey. All black with white hairs here and there.

 

I believe the stray white hairs that suddenly appear are often due to "trama" or scarring on the skin below. Poor Darwin has quite a few white hairs on his head and neck from being tugged on by the naughty youngsters.

Spots where HK has white hairs were bald at one point, probably due to a trauma discussed long ago. Vet said at the time, her fur would probably grow back but may be white from the trauma. I guess that supports your theory.

 

to the best of my knoladge Wilow has never had any trama to this area or anyware that i am aware of ..then again it is her head and who knows what she bumps into outside :-\

 

Saska is two and a half and she has several white hairs also

 

I didn't realise that the white hairs that pop up randomly could be caused from trauma, that would explain KCs "white patches" having been run over by a quad bike on the beach, had barbed wire stuck in her leg, swallowed a drawing pin amongst other things - she should be an albino by now? ;D
