My dog just licked someone who has a cold sore. Can he catch anything from them?

Earlier today, my dog licked a friend who has a cold sore, and now I’m concerned about whether he could catch something from the contact. I’ve read that cold sores in humans are caused by a virus, but I’m not sure how this might affect dogs. Is there any risk for him, or is it nothing to worry about?

Answer

Your concern is understandable. While human cold sores are caused by the herpes simplex virus, it is typically not a threat to dogs, and they cannot contract this virus from humans.

  • Cold sores in humans are caused by a virus that is different from those affecting dogs.
  • Dogs generally do not get cold sores from human contact.
  • It is unlikely that your dog is at risk from brief exposure to someone with a cold sore.

In most cases, there is no need to worry about your dog catching anything from licking a person with a cold sore. The herpes simplex virus, which causes cold sores in humans, is species-specific and does not typically jump from humans to dogs. However, if your dog shows any unusual symptoms, such as sores or behavior changes, it's always a good idea to consult with your veterinarian.
