Both my pits have white coats, one has brown spots and one has black spots and they have both always been very prone to severe skin allergies, outbreaks, hot spots, can’t spend too long in the sun or they get heat rash, they both get this really wild amount of waxy yeast red dark buildup in their ears. I’ve had Luna since she was a pup and just adopted Milo last year and it was crazy that when I adopted Milo, he came with all the same issues.
