First aid for a dog is what you do in the minutes before you reach a veterinarian: keep yourself safe, stop what can be stopped, avoid making things worse and get help fast — and the owners who manage that best are the ones who packed a kit and learned the basics before they ever needed them.
The most important first
- First aid is not a substitute for veterinary care. Call your veterinarian or an emergency clinic as soon as you can.
- Protect yourself. A hurt or frightened dog may bite. Use a muzzle if the dog is not vomiting, and keep your face away.
- Stop bleeding with firm, steady pressure for at least three minutes; add layers rather than lifting the first.
- Poisoning: call first. Don’t make your dog vomit unless a veterinarian or poison control tells you to.
- Pack a kit now, and save your vet’s, the nearest emergency clinic’s and a pet poison helpline’s numbers.

What first aid can and cannot do
In 2026 the RECOVER initiative, an international veterinary collaboration on resuscitation and emergency care, published its first evidence-based guidelines on first aid for dogs and cats. Mandell and colleagues describe 38 treatment recommendations for situations where timely help before reaching a clinic may improve outcomes, including heatstroke, choking, burns, swallowing a toxin, low blood sugar and severe bleeding from a limb. The companion evidence review by Thawley and colleagues also lists the many questions where evidence is still thin. The message for owners: a few simple actions matter, and getting to a veterinarian matters most.
Your dog first aid kit
The Merck Veterinary Manual’s pet owner guide, written by a veterinary surgeon, suggests a kit with:
- a muzzle
- gauze, sterile pads, elastic wrap and adhesive tape
- small blunt-tipped scissors, tweezers or forceps
- saline solution, cotton balls or swabs
- a rectal thermometer and lubricating jelly
- disposable gloves
- splinting materials and a bulb syringe
- a small supply of any daily medicine your dog takes
The same guide lists some products, such as hydrogen peroxide and activated charcoal, that are used for certain poisonings. Use them only if a veterinarian or poison control tells you to; making a dog vomit is wrong for some toxins. Keep the kit in a container with a secure lid, check expiry dates at least once a year, and add a card with your veterinarian’s and emergency clinic’s numbers and your dog’s weight and medical history.
First aid basics
The American Veterinary Medical Association’s first aid advice for pet owners covers the most common situations:
- Bleeding. Press firmly with a clean cloth or gauze for at least three minutes. If blood soaks through, add more layers rather than removing the first.
- Choking. Look in the mouth and remove an object carefully with your fingers if you can see it, without pushing it further in. The AVMA describes back-of-ribcage pressure for small dogs and a modified Heimlich maneuver for large dogs. Go to a clinic even if it comes out.
- Heatstroke. Move the dog to shade, start cooling with wet towels and air flow, and drive to a clinic, cooling on the way. A 2022 review of heatstroke in dogs by Caldas and colleagues describes it as an emergency that can lead to failure of several organs. Our heatstroke article covers cooling in more detail.
- Poisoning. Call your veterinarian, an emergency clinic or a poison helpline. Keep the packaging and any vomit or chewed material.
- Seizures. Move hazards away, don’t restrain the dog or put your hands near its mouth, and time the seizure. The AVMA advises immediate care if it lasts more than five minutes or if two or more happen within 24 hours.
- Burns. Flush with room-temperature water and cover with wet towels on the way to the clinic.
- Shock. Keep the dog warm and quiet; if unconscious, keep the head level with the body.
- Allergic reactions. Facial swelling, hives, vomiting or collapse after a sting, vaccine or medicine need a veterinarian quickly. The RECOVER first aid guidelines include a separate review of acute allergy and anaphylaxis by Burkitt-Creedon and colleagues.
Moving an injured dog
Support the injured area, splint only if you are confident, and confine the dog for transport: a carrier for small dogs, a board or a blanket held taut by two people for large dogs. Drive carefully, and call ahead so the clinic is ready.
Learn it before you need it
The Merck Veterinary Manual points out that you need to know how to use everything in your kit, and that animal first aid and CPR courses are offered through veterinary practices, colleges and organizations such as the Red Cross. An hour spent practicing a muzzle, a pressure bandage and checking breathing is worth more than the most expensive kit.
In practice
A family’s young dog cuts a pad badly on glass at the beach. One person holds and calms the dog while the other presses a folded towel firmly on the paw and keeps adding layers as it soaks through. They call the nearest emergency clinic on the way, and the pad is cleaned and stitched. Afterward they pack a proper kit for the car.
(Illustrative, composite scenario.)
When to call your veterinarian
- Any bleeding that doesn’t stop with pressure, deep wounds, burns or suspected broken bones.
- Choking, difficulty breathing, collapse or pale gums.
- A suspected poisoning, even if your dog seems well.
- A seizure lasting more than five minutes, or more than one seizure in 24 hours.
- Facial swelling, hives or vomiting after a sting, vaccine or medicine.
- If in doubt, call — your vet would rather hear from you early.
Work on it
A few minutes here will teach you more than re-reading the article.
Ask yourself
- Do I know where my nearest 24-hour emergency clinic is?
- Could I muzzle my dog safely if it were in pain?
- Is there a first aid kit in my home and car?
Find out & check
- Look for a pet first aid course near you or online.
Do one thing
- Put together a basic kit this week and tape your vet’s and emergency clinic’s numbers inside the lid.
