Few of the pups have the doggy dandruff. Have checked to see if it is moving and its not so know its not mites. 1 wee girl is really bas and you can feel it under her fur mostly at back legs and at her neck. Gave her a wee bath yesterday using very little shampoo. Might be due to food I am feeding(Royal Canin) but don't want to change that right now as it'll probably upset their tums. Will they just grow out of this or should I do anything else. Remembering the kids got dry skin after a wee while when they were new borns. Do you think this is similar?
