They warn you
long before anything happens.
Dogs almost always signal discomfort well in advance, and the signals are quiet enough to miss if nobody has told you what to look for. Tell the tool below what your dog is actually doing and it will tell you what that means, how urgent it is, and what to do in the next five minutes.

Pick the thing you have actually noticed — the list is grouped by where you would see it, not by how serious it is. You will get what your pet is saying, what to do now, and the one thing not to do.

What escalation actually looks like
Dogs work up a ladder, and they start at the bottom. Almost every “bite out of nowhere” is a dog that climbed the first six rungs in front of somebody who had not been told the rungs existed.
- Blinking, lip licking, yawningQuiet. Almost nobody notices these.
- Turning the head awayStill polite. Still easy to miss.
- Turning the body away, sitting, pawingNow it is asking twice.
- Walking awayThe dog solving it on its own. Protect this rung above all.
- Creeping, ears back, tail lowFrightened, and running out of polite options.
- Standing stiff, staringThe last silent rung.
- GrowlingThe last warning — and the one people punish.
This is the rung people punish. Punish a growl and the dog does not stop feeling what it felt — it learns that every rung below this one failed. The next time, it starts here.
- Snapping, air-bitingA bite the dog chose to pull.
- BitingNo warning left to give.
Thank the growl. Increase the distance. Then get help with whatever put the dog on the ladder in the first place.
Cats do not use the same ladder.
Dogs escalate through warnings you can learn to read. Cats mostly withdraw — and the withdrawal is the warning. A cat that has stopped using a room, stopped eating, or started toileting outside the tray has been telling you for days.
The cat risk that supervision cannot cover is different too: cots are warm, soft and raised, which makes them an excellent cat bed, and cats use them while you are asleep. That is a cot net and a shut door, not a rule. Toxoplasmosis in pregnancy is a litter-tray question for your midwife — someone else changes the tray daily where possible, gloves and thorough handwashing where not.
The seven cat signals are in the tool above, under Cats.
When to stop reading websites and call someone.
If your dog has growled, stiffened, guarded or shown teeth around the baby — or if something simply feels wrong — that is the point to bring in a professional, not to research harder.
Start with your vet: behaviour change is very often medical. Then ask for a referral to an accredited, reward-based behaviourist. Avoid anyone selling dominance, alpha rolls, prong or shock collars — aversives suppress the warnings you most need to keep.
Until you have seen someone, manage it physically: gates or crates, never in the same space unsupervised, no exceptions because you are tired.

If you are thinking about rehoming
If you have done all of that — the vet, the behaviourist, the gates, and practical help like a walker or daycare to protect the dog’s routine — and it is still not safe, this is the part of the subject nobody links to. It happens, it is far more common than people admit publicly, and it does not make you a bad owner.
If rehoming is the right call
- ●Be completely honest about the history. Concealing a bite risks the next family and the dog
- ●Go through a reputable breed rescue or shelter, never a free-to-good-home advert
- ●If you bought from a breeder, contact them — good ones take their dogs back
- ●Ask about an adult-only household. It may be an easy placement, not a tragedy
What we will not tell you
- ●That you must keep a dog that has injured your child
- ●That rehoming a dog you cannot safely manage is a moral failure
- ●That love, effort or the right training video always fixes it
- ●That any household can be made safe. Most can. Not all can
Questions people ask us
My dog has never shown any aggression. Do I really need all this?
Most serious injuries to babies involve a familiar family dog with no bite history. A clean record is genuinely reassuring about temperament — it is not a substitute for management, because the situation your dog is about to face is one it has never encountered.
Is it fine if my dog licks the baby?
We would discourage it. Mouths carry bacteria and a newborn’s immune system is immature — and behaviourally it puts a dog’s face against a baby’s face, the exact position you least want to become normal.
Should I let my dog sniff the baby to get used to them?
Let the dog approach and withdraw on its own terms, from a distance, on a loose lead. Never hold the baby towards the dog or bring the dog to the baby. One gives the dog a choice; the other removes it.
