Why Do Dogs Lick People?

7. Is It Safe for Dogs To Lick People?

Although licking can be unpleasant for some people, it is usually safe to allow your dog to lick you. However, dogs do carry bacteria in their mouths, so it's best to keep them away from any irritated skin, wounds or other sensitive areas. People with compromised immune systems may want to discuss it with their doctors before letting dogs lick them. Some people are also allergic to dog saliva, so a dog licking them can cause hives, itchiness or, in extreme cases, anaphylaxis. If you enjoy letting your pet dog lick you, though, it's generally fine to indulge in the occasional dog kisses.
