Pet First Aid Basics

In a veterinary emergency, the minutes before you reach a clinic can matter enormously. Knowing basic pet first aid skills allows you to stabilize your pet, prevent additional injury, and make the difference between a survivable event and a tragedy.

This guide covers the foundational skills every pet owner should know. It is not a substitute for veterinary care — every injury or illness on this list still requires professional follow-up but it is the bridge that gets your pet there in the best possible condition.

The Pet First Aid Kit

Build a dedicated first aid kit for your pets. Keep one at home and a smaller version in your car.

Essentials:

• Rectal thermometer (digital, with lubricant)
• Gauze pads and rolls
• Self-adhering bandage wrap (Vet Wrap / CoFlex)
• Medical adhesive tape
• Blunt-tipped scissors
• Sterile saline eye wash
• 3% hydrogen peroxide (for inducing vomiting ONLY when directed by a professional — never without guidance)
• Betadine (diluted for wound cleaning)
• Sterile gloves
• Oral syringe or turkey baster
• Emergency contact card: your vet’s number, nearest emergency hospital, ASPCA Animal Poison Control (888-426-4435), Pet Poison Helpline (855-764-7661)
• A muzzle appropriate for your dog’s size (injured dogs bite even beloved owners)
• Your pet’s medical records summary, including vaccination history and current medications

Checking Vital Signs

Know how to assess your pet’s vital signs so you can communicate clearly with emergency staff.

Temperature: Insert a lubricated thermometer 1 inch into the rectum for 30-60 seconds. Normal: 101-102.5°F. Below 99°F or above 104°F is an emergency.

Gum color and moisture: Lift the lip and observe the gum color. Healthy gums are pink and moist. Press and release a gum — color should return within 2 seconds (capillary refill time). Pale, white, blue, or grayish gums indicate a crisis. Brick red or yellow gums also indicate serious problems.

Respiratory rate: Count breaths for 30 seconds and double. Normal rest: 15-30 for dogs, 20-30 for cats.

Heart rate: Place your hand or a stethoscope on the left chest behind the front leg. Count beats for 15 seconds and multiply by 4. Normal: 60-140 for dogs, 140-220 for cats.

Bleeding

Minor wounds: Clean with saline or clean water. Apply gentle pressure with a gauze pad for 5-10 minutes. Once bleeding stops, apply a bandage loosely enough to allow two fingers underneath. Do not wrap too tightly — this cuts off circulation. See a vet for any but the most superficial wounds.

Severe bleeding: Apply firm, direct pressure with the cleanest available material. Do not remove soaked material — add more on top. Transport immediately. If blood is pulsing rhythmically (arterial), apply pressure above the wound as well. Note the time you applied pressure. Tourniquets are a last resort and require medical expertise to use safely — apply only to a limb, note the time, and do not remove until the vet instructs you to.

Internal bleeding: Suspected when a pet collapses, has pale gums, rapidly worsening weakness, or a distended abdomen after trauma. There is no field treatment. Transport immediately.

Choking

A choking pet is panicking and will instinctively bite. Approach carefully.

If your pet is conscious and choking: Look into the mouth if it is safe to do so. Only reach in to remove an object if you can clearly see and grasp it. Do not blindly probe — this can push the object deeper.

Heimlich maneuver for dogs: Stand behind your dog and wrap your arms around their abdomen. Make a fist just below the rib cage, place your other hand over it, and deliver 5 firm, upward thrusts into the abdomen. Check the mouth after each set.

Modified technique for cats and small dogs: Hold the animal with their back against your chest. Use two fingers just behind the rib cage to deliver quick, firm upward thrusts.

If the animal loses consciousness, open the airway and check for the object before beginning CPR.

Cardiopulmonary Resuscitation (Pet CPR)

Pet CPR is performed when a pet is unresponsive, not breathing, and has no heartbeat.

Check for consciousness: Call their name, tap gently. If no response, check breathing and pulse.

Open the airway: Tilt the head back gently to extend the neck. Check for visible obstructions in the mouth.

Check for breathing and pulse: Watch for chest movement. Feel for a heartbeat on the left chest behind the front leg.

For dogs: Lay the dog on their right side. Place hands over the widest part of the chest (not the sternum). For large barrel-chested breeds (Bulldogs, Pugs), lying on the back with hands on the sternum may be more effective. Compress 1/3 to 1/2 of the chest depth. Give 30 compressions (at roughly 100-120 per minute the rhythm of “Stayin’ Alive”), then give 2 rescue breaths by closing the mouth, extending the neck, and blowing into the nose until you see chest rise.

For cats and small dogs: Wrap one hand around the sternum. Compress with thumb and fingers on either side. Give 30 compressions, then 2 rescue breaths as above.

Continue 30:2 cycles until the pet breathes on their own, someone takes over, a veterinarian takes over, or you are physically unable to continue.

Taking a formal Hands-On Pet CPR and First Aid course from a certified provider is highly recommended. The Red Cross offers Pet First Aid classes, and many veterinary organizations host them as well.

Burns

Chemical burns: Flush immediately with large amounts of water for 20 minutes. Do not apply neutralizing agents. Cover loosely with a clean bandage and transport.

Heat burns: Cool with cool (not cold or iced) water for 10-15 minutes. Do not apply butter, oil, or toothpaste. Cover loosely and transport.

Electrical burns: Do not touch the animal until the power source is off and you are certain the current is disconnected. Transport immediately.

Heatstroke

Heatstroke is a true emergency. Do not wait to see if the pet “recovers on their own.”

Signs: excessive panting, drooling, bright red gums, vomiting, wobbling, collapse.

Move to shade or indoors immediately. Apply cool (not iced) water to the paws, groin, and armpits. Place wet towels on the neck, armpits, and groin. Fan the pet. Transport immediately while continuing cooling measures. Do not use ice or ice water rapid temperature drops can cause shock.

Poisoning

If you know or suspect your pet has ingested a toxin, call ASPCA Animal Poison Control (888-426-4435) or your emergency vet immediately. Do not induce vomiting without professional guidance some toxins cause more damage on the way back up.

Bring the packaging of any suspected toxin to the vet.

The Most Important First Aid Skill

Stay calm. Panicked owners make panicked decisions. Take one breath, assess the situation, call for help, and focus on stabilizing the animal until you reach professional care. You do not need to fix the problem you need to keep the situation from getting worse until the vet can fix it.
