Dog Lick Q&A

Below are some common questions and facts about dog licks.

Are Dog Licks Clean?

“Clean” isn’t an easy word to use for describing dog licks. Dog saliva has some characteristics that make humans think it’s clean, but we wouldn’t recommend using your dog’s saliva to clean your dishes. Dog saliva is antibacterial which is why they often lick their wounds. The saliva creates a film on the wound which numbs the area and reduces the pain. However, the bacteria in dog saliva can be harmful to humans which is why you should not let your dog lick any wounds you have because it could lead to infection.

Is A Dog’s Mouth Cleaner Than A Human’s?

I can’t tell you how many times I’ve been told that a dog’s mouth is cleaner than a human’s. I don’t mind kisses from my dog, but I’m not crazy about her kissing my mouth, that’s where I draw the line. “A dog’s mouth is cleaner than a human’s” is a complete myth. Think about it, dogs (not all) sometimes lick their private region, eat out of the trash, bring dead animals to the doorstep and drink out of the toilet. Humans (not all) brush their teeth twice a day, floss once a day, use mouthwash daily and don’t do any of the things listed above that dogs do.

Are Dogs’ Mouths Clean?

It depends on the dental hygiene practices used by the pet parent. A dog who has its teeth brushed, eats dental chews and visits the vet regularly probably has a cleaner mouth than a stray dog. It also can depend on the dog. Some dogs are predisposed to periodontal disease and other dental issues.

Is It Bad To Kiss Your Dog On The Mouth?

Surprisingly, there are mixed opinions on this. I assumed that when I researched this question, I’d come up with, “Yeah, it’s fine to kiss your dog on the mouth, it’s just not the cleanest,” but I was wrong. In most instances, your dog licking your face is harmless. However, in some instances, the transmission of disease between pets and people can be very serious. If you have an open wound or sore and the bacteria from your dog’s saliva contacts comes in contact with it, you could obtain an infection that can progress quickly. However, many times the infection can be treated with antibiotics. This is why you shouldn’t let your dog lick your face, period.

What Animal Has The Cleanest Mouth?

Unfortunately, it’s difficult to answer this question because animals have different types of oral bacteria, so it’s like comparing apples to oranges.
