Now, human flu is a different story. Some strains of influenza can occasionally pass to dogs, especially if you’re dealing with H3N2 or H1N1. But again, it’s super rare, and dogs usually just get a mild cough. And even then, they’re more likely to pass it back to you. So if you have the flu, maybe keep a little distance. Not because you’re a monster, but because flu is a bully.
For your standard, everyday head cold? Zero risk. You’re safe to sneeze all over your dog… please don’t actually do that, but you could.
