Spotty discoloration on stomach
Hey everyone I have a five month old boy that has developed a spotty discoloration on his belly in the past two months. It's more prominent around his center stomach and inner thighs. He doesn't scratch or lick at all but it has become a little worse in the past couple weeks. I have also noticed where the pigmentation is there is also thinning hair, which also seems to affect his ears aswell. I have been to three vets, one told me sunburn, the second told me pretty much it was nothing to worry about and it was normal for pits color to change and loose some hair during season change, and the third said it was environmental allergies and gave me some hypoallergenic shampoo but it has not helped. He has been tested for mange (skin scrape) and parasites (stool sample) but both were negative. Anyone ever heard of this or dealt with it personally any feedback would be great Im outta ideas here. Thanks.
