A little licking on the hands or feet isn’t something to panic about.
It’s the face that deserves the actual caution — everywhere else, this is one of the smaller things on your list right now.
A dog’s mouth carries a normal population of bacteria, some of which can occasionally cause illness in a newborn whose immune system is still developing. This doesn’t mean licking is dangerous in any dramatic sense, but it does mean “harmless” isn’t quite the right word either — the honest answer sits somewhere in between.
Where the actual caution belongs
The areas of real caution are the baby’s face, particularly the mouth and any open skin, like a healing umbilical cord site. Licking on hands or feet carries meaningfully lower risk than facial contact, simply because of what’s actually being touched and how likely that contact is to reach the baby’s own mouth afterward.

What actually reduces the risk
Most of the actual risk reduction here is simple: redirect face-directed licking calmly, without a dramatic reaction that might make your dog more curious about the behavior rather than less. Regular handwashing for the baby’s hands, the same general hygiene habit you’re likely already practicing, further reduces whatever residual risk remains from incidental licking elsewhere.
What this isn’t a reason to do
This isn’t a reason to keep your dog entirely away from the baby, or to treat every interaction as risky. It’s a reason to gently manage where licking happens, the same low-key way you’d manage any other minor safety detail during this stage — not a source of ongoing worry, just one small habit worth guiding.
As your baby gets older and their immune system matures, this becomes less of a specific concern, though redirecting face-licking remains a reasonable habit regardless of age, for hygiene reasons that apply to everyone in the house, not just infants.
Where this lands: brief licking on hands or feet is a low-risk normal part of having a dog around a baby. Face-directed licking is worth gently redirecting, not treating as an emergency — just a small, manageable habit.
