Introducing your dog to a baby: the months before matter more than the day
The first meeting gets all the attention, but it is the easy part. What actually keeps a baby and a dog safe is what you change in the months before the birth, and how you read the dog in the two years after. A plan, and the signs to watch.

Everyone worries about the first meeting. It gets planned, photographed and posted. And it is the least important part. Most dogs are curious and careful with a newborn, and most of the real difficulty comes later — when the baby is mobile, grabbing, loud and at the dog's eye level, and everyone has stopped paying attention.
So the plan runs in three stages: the months before, the first weeks, and the two years after. The middle one is the short one.
Before the birth: change the things that will change
A dog's world is about to be rearranged. Do it gradually now, so the baby is not blamed for it.
- The routine. Walks will move; the dog will be alone more; the sofa may become off-limits. Make those changes over the last two months, not the first week home. A dog that lost its walk the day the baby arrived learns the obvious lesson.
- The sounds. Play recordings of babies crying, at low volume with treats, building up over weeks — the same method as for fireworks. A crying newborn is a noise most dogs have never heard.
- The rooms. Decide now where the dog will not go — the nursery, the changing area — and install the gates now. Teach the dog to settle on a mat or in its bed on cue, somewhere it can see you, because "go to your bed" will become the most useful sentence in the house.
- The handling. Babies grab ears, tails and fur. Practise gentle touching of ears, paws and tail paired with treats, so the dog's association with being handled clumsily is a good one. This does not make grabbing acceptable — it makes the dog more forgiving when it happens anyway.
- The vet. Vaccinations and worming up to date, and a check-up. A dog in pain is a dog with a shorter fuse, and arthritis is the commonest hidden reason a middle-aged dog becomes snappy with a toddler.
- Any existing problem. Guarding food or toys, fear of strangers, snapping when disturbed asleep: these are the things to fix with a trainer now, with months in hand.
The first weeks
Before the baby comes home, bring something home first — a blanket or a worn babygrow — and let the dog sniff it while you stay calm and pleasant.
The first meeting is small. Someone the dog loves greets it first, alone, so the excitement of the reunion is spent before the baby is involved. Then, with the dog on a loose lead and one adult holding the baby, let the dog approach and sniff at its own pace. Calm voice, a treat, done. Keep it short. Repeat it several times a day for a few days. Do not hold the baby out towards the dog's face, and do not force the dog to look.
Then be boring about it. The dog gets attention when the baby is present — a treat, a word — and is ignored when the baby is not. That way the baby predicts good things. Most people do the opposite without meaning to, and the dog learns that the baby means it gets pushed away.
The two years after: the part that matters
The risk to a child from a family dog rises sharply once the child can crawl, and again as a toddler. Almost all bites to young children come from a dog the family knows, almost always to the face, and almost always when an adult was in the room but not watching. The dog is nearly always one that had been "fine" and had been giving signals nobody read.
Three rules cover most of it:
- Never alone together. Not for a minute. Not the sleeping baby and the dozing dog. If you leave the room, one of them comes with you or a gate goes between them.
- The dog can always leave. A bed or crate the child cannot reach, a room with a gate, a place to go. A dog that can walk away from a grabbing toddler does not have to bite to end it.
- You do the child's training too. From the first crawl: no climbing on the dog, no touching it while it eats or sleeps, no taking things from it, no hugs around the neck. Toddlers do not understand this, which is why rule one exists; but they learn it eventually, and it is the parent's job, not the dog's.
The signs a dog gives before it bites
A dog almost never bites without warning. It warns in a language most people were never taught:
- Turning the head away, showing the whites of the eyes ("whale eye").
- Licking its lips or yawning when nothing is happening.
- A stiff body, a closed mouth where a moment ago it was open.
- Getting up and moving away — the most important one, and the one people most often undo by bringing the child back over.
- A growl.
Do not punish the growl. A growl is the dog asking for space in the politest way it has. Punish it and you teach the dog to skip that step next time. The right response is to take the child away, give the dog space, and think about what you missed.
When to ask for help
If the dog has ever growled or snapped at the child, if it guards anything, if it hides when the child appears, or if you simply feel uneasy: a qualified behaviourist, by referral from your vet, before the toddler stage — not after an incident. Most of these situations are manageable with a plan. Very few are manageable by hoping.
We put the dog's health history, its vet and its routine in mypet care for the practical reason that a household with a new baby has no spare attention — the booster date, the last worming, and the note "gets snappy when his hip hurts" have to be somewhere other than in someone's head.
