My Dog Is Bleeding — How Do I Stop It?

Firm, direct pressure with a clean cloth — held for five full minutes without lifting — stops most bleeding a dog can produce at home. Blood that spurts in time with the heartbeat, soaks through pad after pad, or comes from the chest, belly or mouth is a drive-to-the-emergency-clinic situation, and you press the whole way there.

Pressure is the entire technique

Everything else is detail. Put a clean cloth, gauze pad, or in a pinch a folded t-shirt directly over the wound and push. Not a dab — steady weight, the same force you would use to press a bruise on yourself.

Then leave it alone. The instinct to lift the cloth and check is the single most common mistake, and every check strips off the clot that was forming and sets the clock back to zero. If blood soaks through, add another layer on top of the first. Never peel the soaked one off.

Five minutes feels far longer than you expect when a dog is bleeding and someone is shouting. Set a phone timer.

How urgent is it?

Gum colour is the check worth learning before you need it. Lift a lip on a healthy relaxed dog and look: bubblegum pink is normal. Pale, white or grey gums in an injured dog mean circulating blood volume is dropping, and that is an emergency whether or not you can see where it is going.

Tourniquets: almost never

A tourniquet cuts off all circulation to a limb. Applied wrongly or left on too long it costs the dog the leg. In a home setting, direct pressure and a firm pressure bandage handle essentially everything a tourniquet would, and they do it without that risk.

The honest version: a tourniquet is a technique for someone trained, in a catastrophic limb injury, with a clinic minutes away. If you have never been taught, press hard on the wound and drive.

Cleaning a wound you are handling at home

For a graze or a shallow cut that has stopped bleeding:

1. Trim the hair back around the edges with blunt scissors if you can do it without stress. Hair in a wound holds dirt against it.
2. Rinse with lukewarm water or plain saline, gently and generously. Saline is easy to make — a level teaspoon of salt in a pint of boiled and cooled water.
3. Pat dry, do not rub.
4. Leave it uncovered unless your vet has told you otherwise. Most small wounds do better with air than under a home bandage that traps moisture.
5. Stop the licking. A cone is unglamorous and it is the reason the wound heals in a week rather than turning into an infected mess.

Check it twice a day. Swelling, heat, a bad smell, yellow or green discharge, or a dog that goes quiet and off its food all mean the wound is infected and needs antibiotics you cannot buy yourself.

Things not to put on a dog

• Hydrogen peroxide — damages healing tissue and stings badly.
• Rubbing alcohol — same problem, more pain.
• Human antibiotic ointments — some are fine, some are not, and your dog will lick off whatever you apply. Ask first.
• Flour or cornflour on anything but a bleeding nail — it works on a nail tip and contaminates a real wound.
• Any human painkiller. Ibuprofen, paracetamol and aspirin all cause serious harm in dogs, and the dose that does it is smaller than most owners assume. Our guide to human medications toxic to dogs covers why.

Bite wounds look small and are not

A puncture from another dog's tooth seals over in minutes and hides crushing and tearing underneath. Bacteria go in with the tooth and stay there. This is the wound category that most reliably turns into an abscess three days later, and it is why every bite gets seen the same day even when it looks like nothing.

The same goes for anything that punctured deeply — a stick, a fence spike, a fishhook. Do not pull out an object that is still embedded. It may be the only thing holding a vessel closed. Pad around it, keep the dog still, and drive.

Bleeding you cannot see

A dog hit by a car, kicked, or fallen from a height can bleed internally with almost nothing visible on the outside. The signs are pale gums, fast shallow breathing, a swollen or tender belly, weakness, and cold paws and ears. Any dog that has taken that kind of impact goes to a vet the same day even if it gets up and walks away, and even if the only thing you can report is that it seems subdued.

Rodent bait is the other cause worth naming, because it stops blood clotting days after the dog eats it. If that is a possibility, read antifreeze and rodenticide emergencies and call now rather than waiting for a symptom.

What to do next

Put a pack of gauze, a roll of self-adhesive bandage and a bottle of saline somewhere you can reach in the dark — that is most of what a dog first-aid kit is for. Then save your regular vet and your nearest 24-hour emergency clinic in your phone under names you can find while panicking. The five minutes you spend on that today is the five minutes you will not have later.
