My shih tzu has started getting these weird spots on her lower belly and on her back legs. It started with just one small one, but it has spread. They look lke birth marks or moles, but they're not raised much from the skin. The skin isn't red or irritated, and it doesn't seem to bother her. A friend said that it's probably just a skin discoloration. I was just wondering if anyone else had a similar problem before I take her to the vet.
Your friend could be right. It could just be some pigment comming into the skin. how old is your dog? alot of breeds do that when they are young. It never hurts to have your vet check it just to be onthe safe side. If the dog is older, skin cancer can start as dark spots.
