Hi All It’s a mystery, my previous black labrador puppy has been gaining more bad more white hair all down her back and tail. It starts white at the roots and then turns black so hair seems to be white tipped! Im not sure if this is a genetic problem (she comes from a long line of FT champions) or a skin/ dietary problem? Will try and attach a photo below but she sheds excessively too and does bite her rear leg area a lot- I could make a rug with the amount of hair that comes out in handfuls.. Any thoughts? I’ve worked out she also has a problem with gluten ( had terrible diarrhoea initially as a puppy) would appreciate any thoughts.. thanks
