An emergency is the worst time to learn first aid. The best time is now, on a quiet afternoon, before anything has gone wrong. This guide walks through the handful of situations most likely to threaten your dog or cat, and what to do in the minutes that matter most.
One thing to keep front of mind the entire time you read: first aid is meant to stabilize your pet on the way to a veterinarian. It is not a substitute for one. Everything below buys time. It does not replace a professional exam, diagnosis, or treatment.
If your pet is in distress, call your veterinarian or your nearest 24-hour emergency animal hospital right now. For a suspected poisoning, call the ASPCA Animal Poison Control Center at (888) 426-4435 (a consultation fee may apply). Put both numbers in your phone today, and write them on a card in your first-aid kit. When something goes wrong, you should not be searching the internet — you should be dialing.
This article draws on publicly available guidance from the American Red Cross Pet First Aid program, the American Veterinary Medical Association (AVMA), and the ASPCA Animal Poison Control Center. It is general education, not medical advice for your specific animal. The single most valuable thing you can do after reading is sign up for a hands-on pet first-aid and CPR class — the Red Cross and many local veterinary clinics offer them. Reading about chest compressions is not the same as practicing them on a manikin.
Before an emergency: build a kit and know where to go
Preparation is the part of first aid you control completely. Two things make the biggest difference.
- Assemble a first-aid kit and keep it where you can grab it — one for home, a smaller one for the car. Check it twice a year and replace anything expired or used. See the table below.
- Know your nearest 24-hour emergency vet before you need it. Daytime clinics close; emergencies don’t. Look up the address and phone number, save them, and know how long the drive takes.
- Save the ASPCA Animal Poison Control number, (888) 426-4435. It’s staffed around the clock, every day of the year.
- Keep a copy of your pet’s medical records — vaccinations, medications, known conditions — with the kit. An unfamiliar emergency vet will move faster with them.

Choking
A pet pawing at the mouth, gagging, struggling to breathe, or turning blue may be choking.
- If your pet can still cough, breathe, or make sound, let them keep coughing — coughing is the body’s own best tool for clearing an airway. Get to a vet.
- If you can clearly see an object in the mouth, try to gently remove it with tweezers or your fingers. Do not push it deeper, and do not blindly sweep your fingers down the throat — you can lodge the object further or be bitten.
- For a small pet, hold them with the head pointed down. For a larger dog, you can place your hands just behind the last ribs and apply firm, quick pressure inward and upward, a few times.
- Get to a vet immediately, even if the object comes out — the airway may be injured.
Bleeding and wounds
- Apply firm, steady direct pressure with a clean gauze pad or cloth over the wound. This is the single most effective thing you can do.
- If blood soaks through, add more material on top — do not lift the original dressing, which can tear away a forming clot.
- Keep pressure on for several minutes without peeking. Once bleeding slows, you can wrap the dressing in place with self-adhesive wrap, snug but not so tight it cuts off circulation.
- Heavy, spurting, or non-stop bleeding is a true emergency. Maintain pressure and get to a vet now.
- Even a wound that looks minor can be deeper than it appears, especially a bite or puncture. Have it checked.
Suspected poisoning
Poisons hide in plain sight: chocolate, xylitol (in sugar-free gum and many products), grapes and raisins, certain houseplants, human medications, rodent bait, antifreeze.
- Call first. Contact your veterinarian or the ASPCA Animal Poison Control Center at (888) 426-4435 immediately. Have the product, packaging, or plant on hand so you can describe what, how much, and when.
- Do not induce vomiting unless a veterinarian or poison control specifically tells you to. Some substances — corrosives, petroleum products — cause far more damage coming back up, and home methods can be dangerous in their own right. Never give salt, hydrogen peroxide, or anything else on a hunch.
- If poison is on the skin or coat, follow the guidance you’re given about rinsing.
- Bring the packaging or a sample of the plant with you to the vet.
Heatstroke
Hot cars, humid days, and over-exercise can push a pet’s temperature to dangerous levels. Watch for heavy panting, drooling, weakness, vomiting, or collapse. This is a life-threatening emergency.
- Move your pet to shade or a cool, air-conditioned space right away.
- Cool gradually with cool or room-temperature water — wet the body, especially the belly and paws. Do not use ice or ice-cold water, which can constrict blood vessels and make cooling less effective.
- Offer small sips of cool water if your pet is alert and willing — never force it.
- Go to the vet immediately, even if your pet seems to recover. Internal damage from heatstroke isn’t always visible, and cooling too far is also dangerous — a vet will monitor the temperature for you.
Seizures
A seizing pet may collapse, stiffen, paddle their legs, drool, or lose control of their bladder. It is frightening to watch, but most seizures pass within a couple of minutes.
- Do not restrain your pet and keep your hands away from the mouth. A seizing animal isn’t aware and can bite hard; the old myth about swallowing the tongue is false.
- Clear the area of furniture, stairs, and anything hard or sharp so they can’t injure themselves.
- Time the seizure. Note when it starts and stops — your vet will want this.
- Keep the room calm, quiet, and dimly lit. Afterward, your pet may be disoriented for a while; speak gently and let them recover.
- Call your vet. A seizure lasting more than a few minutes, or one seizure right after another, is an emergency — go now. A first-ever seizure also warrants a prompt call.
If your pet isn’t breathing: CPR
This is the situation where the gap between reading and doing is widest. The most important step you can take is to learn pet CPR properly in a hands-on class, such as those offered through the American Red Cross. Performed incorrectly, chest compressions can cause harm, and you cannot learn the rhythm, depth, and hand position from a paragraph.
- Check whether your pet is responsive and breathing. If there is no breathing and no heartbeat, CPR may be warranted.
- CPR combines chest compressions with rescue breaths, at a depth and pace suited to your pet’s size. The technique differs for a small cat versus a large dog.
- If at all possible, have someone drive you to the emergency vet while you perform CPR — care should be continuous until a professional takes over.
Again: take the class. It is the best gift you can give a pet you love.
Broken bones and being hit by a car
A pet hit by a car needs to be seen even if they get up and seem fine — internal injuries, bleeding, and shock can be invisible at first.
- Minimize movement. Don’t try to splint or straighten a limb; you can worsen the injury and cause severe pain.
- Approach calmly and watch for bites (see below). Slide your pet onto a firm, flat surface — a board, a stiff piece of cardboard, or a towel used as a sling for a small animal — to keep the body as still as possible.
- Keep them warm and quiet to help counter shock.
- Get to a vet right away, supporting the body and avoiding twisting.
Safely muzzling and moving a hurt, scared pet
The most loving pet may bite when in pain — it’s instinct, not a betrayal. Protecting yourself protects your ability to help.
- For a dog, a soft strip of cloth, gauze roll, or a leash can form a temporary muzzle: loop it over the snout, cross underneath, and tie behind the ears. Never muzzle a pet that is vomiting, choking, struggling to breathe, or showing signs of heatstroke — they need an open airway.
- For a cat or small animal, gently wrap the body in a towel or blanket, leaving the face out, to limit scratching and biting.
- Move an injured pet as little and as smoothly as possible. Support the whole body; use a blanket or board as a stretcher for a large dog.
- Stay calm. Your tone and movements set theirs.
When in doubt, go to the vet
Every step in this guide leads to the same place: professional care, as fast as you can safely get there. First aid is what you do on the way — it buys minutes, not cures. If you’re ever unsure whether something is an emergency, treat it as one and go in. It is far better to be wrong about an emergency than to wait too long.
Take a hands-on pet first-aid and CPR class, build your kit this week, and save those two numbers — your nearest 24-hour emergency vet and ASPCA Animal Poison Control, (888) 426-4435 — before you ever need them.
