So pleased he’s home. What a rollercoaster you’ve had.
Snowie’s skin that’s covered in fur is pink. The exposed skin is very dark, but it’s under his tummy which hardly ever sees the sun. I don’t think it’s a suntan in this case, just that it’s exposed and probably being irritated by the grass and licking etc. I’d first test a small part of Homer’s skin with sunscreen before using it everywhere. I know with myself, I get a rash if I’m wearing sunscreen and get very hot. Perhaps rather just keep him indoors when the sun is overhead (strongest)? If he needs to go out, I don’t think a few minutes in the sun will cause sunburn. In fact, here the recommendation from some dermatologists is to expose your skin without sunscreen for 20 mins everyday when the sun is overhead (strongest) to ensure adequate Vit D (of course, not to burn). Not sure how that works in dogs though!
