So I'm wondering if I need to go to the vet tomorrow. Noticed happydog seemed to have a bit of a scrape over her eye Friday, only it didn't look like a fresh wound. Over the past few days it seems to be getting bigger. It looks like a small patch of very dry, scabby skin with some hair loss. She isn't scratching it or seemingly bothered by it but I want to catch it before it gets bigger, currently about the size of 3 dried grains of rice. New to dog "ownership" here, what could be afflicting my darling?
