Change In Hair Colour (overnight)

[Pep]

I have an all back Labrador puppy who appears to be healthy and happy (vet checked just over a week ago). Last night when she went to bed she was all black! This morning, I noticed she had silvery white specks on her legs. I thought she must have brushed against something (although I couldn't think what) so bent down to dust her off, only to find to my surprise that the dust was a collection of white hairs randomly dotted across the front of each leg between her paw and knee joint. They're single strands, no clumps of white, and only appear on the lower legs. The rest of her coat is shiny black and she has experienced no hair loss except for the usual shedding of the puppy coat. Her mother was black and her father yellow. I have never encountered this before and wondered what it might be. Any suggestions?

Can you post a pic ?

If she had pustular dermatitis on her tummy she may have had it on her legs as well. It may not have been obvious as the hair is very short and dense on their lower legs and it's difficult to part it to see the skin.

White hairs can appear where the skin has been damaged - it makes sense that this may be the case considering that the hairs are single and dotted around her legs (similar to a pattern of dermatitis).

I was thinking some sort of skin condition.

Cooper has tiny little grey patches on his head, from when he's been playing too rough and he had little scabs. The hair has grown back white/grey, just in tiny patches.

Re the camera ... I would if I could but unfortunately the only camera I have went on the fritz last week. A description is the best I can do at this stage.

Re the impetigo ... she did have spots on her belly that cleared within days of the salt treatment. Her body was checked daily but perhaps some spots were missed??? There's nothing there now but it makes sense ... cheers for the feedback!
