When I brought Monkey home at 5 m.o. all her skin was white. Soon after, I noticed that her anus had turned black. Now, at 2 y.o. the skin on her belly and underarms is grey (still smooth and healthy) although inside her ears, and anywhere that she has hair (she has tan fur) the skin is still pale. I just wondered if any of this might give a clue to her breeding - she certainly looks like a pug mix, do most pugs have skin like this? I know that westies do, but she definitely doesn't look like a westie otherwise.
