Dog Licking Baby: Is It Safe and How to Stop It
Is it safe for a dog to lick a baby's face? The health facts, why dogs lick babies, and a calm, reward-based plan to redirect the licking.
Your dog sniffs the baby, then out comes the tongue. Some parents find it sweet. Others feel a jolt of worry.
Both reactions make sense. Licking is usually a friendly behavior, but a dog's mouth isn't clean, and a newborn's immune system is still developing. The good news: you don't have to choose between a happy dog and a healthy baby. You can teach your dog a different way to say hello.
This article covers the health side, why dogs lick babies, and a step-by-step plan to redirect licking. This is general information; ask your pediatrician and your vet about your situation.

Is it safe for a dog to lick a baby's face?
The short answer: it's best to avoid it, especially on the face and with newborns.
Dog mouths naturally carry many kinds of bacteria. Most of the time, a lick on healthy skin causes no problem. But there are rare case reports of infants developing serious infections after contact with a pet's saliva, including infections with Pasteurella, a bacterium commonly found in dogs' and cats' mouths. These cases are uncommon, but young babies can get sicker faster than older children.
Areas to protect most:
- The face, especially the mouth, nose and eyes.
- Hands, which go straight into the mouth.
- Any broken skin, rash, scratch or the umbilical cord area in newborns.
- Pacifiers, bottles and teethers, which should never be licked or shared.
Simple hygiene that helps
The CDC's "Healthy Pets, Healthy People" guidance focuses on a few basic habits. They apply well to a home with a baby:
- Wash hands with soap and water after touching the dog, and before feeding or handling the baby.
- Wipe the baby's skin with a clean cloth if the dog licks them.
- Keep your dog's vet care current, including vaccines, regular checkups, deworming and parasite prevention.
- Clean up after your dog promptly, in the yard and indoors.
- Keep dog bowls and toys away from the baby's things.
Pediatric guidance, such as from the American Academy of Pediatrics on HealthyChildren.org, generally encourages caution around pets in the newborn months: close supervision, good hygiene and no unsupervised contact. Your pediatrician can tell you what's right for your baby, especially if they were born early or have health concerns.
Why does my dog keep licking my baby?
Licking can mean several different things. Knowing which one helps you respond the right way.
- Greeting. Many dogs lick faces to say hello. It's a social behavior they learned as puppies.
- Investigating smells. Babies smell interesting: milk, formula, spit-up, lotion and diapers. Your dog may be "tasting" what he smells.
- Appeasement or stress. Some dogs lick to calm a situation or show they mean no harm. Lip licking, a lowered body, ears back or turning the head away can mean your dog is uneasy, not happy.
- Habit and attention. If licking got smiles and laughter in the past, your dog may repeat it.
Watch body language. A loose, wiggly dog licking once is very different from a stiff dog licking repeatedly while showing the whites of his eyes. If you see stiffness, freezing, staring or growling, separate them and read our guide on a dog growling at baby.
Table: why your dog licks, what it looks like, what to do
| Why your dog licks | What it looks like | What to do |
|---|---|---|
| Greeting | Loose body, wagging, licks when the baby arrives in the room | Teach a hand-target hello, reward calm sniffing at a distance |
| Investigating smells | Focused sniffing, licks hands, face or clothes after feeds | Wipe milk off the baby, use a gate during feeds, reward "go to mat" |
| Appeasement or stress | Lip licking, ears back, low body, head turned away | Give more space, a retreat spot, and ask a professional if it continues |
| Habit or attention | Licks, then looks at you for a reaction | Don't laugh or praise licking, reward calm behavior instead |
How to stop your dog licking your baby: a step-by-step plan
The goal isn't to scold your dog. It's to give him a better job and make it pay well. Reward-based methods, as recommended in the AVSAB Position Statement on Humane Dog Training (2021), are kind and effective.
1. Manage first
Use baby gates, a leash or a crate so your dog can't practice licking while you train. Never leave the dog and baby alone together. Management prevents mistakes, so training goes faster.
2. Teach "touch" (hand target)
Hold your open palm near your dog's nose. When he bumps it with his nose, say "yes" and give a treat. Repeat until he does it quickly. Then add the word "touch."
This gives your dog a polite way to greet: he says hello to your hand, not the baby's face. Practice without the baby first.
3. Teach "go to mat"
Reward your dog for lying on a mat or bed a few feet from where you feed or hold the baby. Start with short times and build up. Our guide to dog skills before baby explains how to teach it in small steps.
4. Reward calm sniffing at a distance
With your dog on leash and another adult holding it, let him look at and sniff toward the baby from a short distance. Reward him for sniffing without licking, then calmly move him away. Keep sessions very short.
This is similar to the first meeting described in our guide to introducing your dog to your newborn.
5. Redirect, don't punish
If your dog starts to lick, calmly ask for "touch" or "go to mat" and reward that. Don't yell or push him away roughly. That can make him anxious around the baby, which may increase appeasement licking.
6. Keep it consistent
Make sure every adult and visitor follows the same rules. If one person lets the dog lick, the habit stays alive. Planning these routines ahead with the free Prep Planner can help everyone stay on the same page.
Composite example (based on common cases, not a real family): A young couple's beagle mix licked their newborn's hands every time the baby was fed. They noticed the licking always came after bottles. They started wiping the baby's hands and chin after feeds, set up a gate during feeding time and taught the dog to lie on a mat nearby for a chew. Within a few weeks, the dog went to his mat on his own when the bottle came out. They still keep the dog off the baby's face and supervise every interaction.
Results vary from dog to dog, and we can't promise a specific outcome. If your dog's licking comes with stiffness, growling or any snapping, contact your vet and a qualified behavior professional right away.
