Dog First Aid Basics: What to Do Before You Reach the Vet

Emergency signs: go immediately

The following signs always require immediate emergency veterinary care. Do not wait to see if the dog improves — minutes matter for several of these conditions.

Bleeding and wounds

For minor cuts and scrapes: rinse with clean water or sterile saline, apply gentle pressure with gauze for 3–5 minutes, and monitor for infection (redness, swelling, discharge) over the next 24–48 hours. Small wounds that stop bleeding quickly can often be assessed at a regular vet appointment.

For significant bleeding: apply firm, direct pressure with clean gauze or cloth and maintain it — do not keep checking, as removing the dressing disrupts clot formation. If blood soaks through, add more material on top rather than replacing. Transport to an emergency vet with pressure applied. Tourniquets are a last resort for life-threatening limb bleeding only.

Puncture wounds and bite wounds require vet attention even if they appear small. The entry wound is often misleading — internal damage and infection risk can be significant.

Choking

A choking dog will paw at its mouth, show extreme distress, make high-pitched or no sound while trying to breathe, and may have blue or grey gums. If the dog is still conscious:

1. Restrain calmly — a panicking dog may bite even without intent.
2. Open the mouth and look for a visible obstruction. Only attempt removal if clearly visible and graspable — do not blindly sweep the throat.
3. If you cannot remove it, perform back blows: 5 firm strikes between the shoulder blades with the heel of your hand.
4. For larger dogs, perform a modified Heimlich: stand behind the dog, wrap arms around the abdomen just behind the ribcage, and apply 5 inward-upward thrusts.
5. After any choking incident, even if resolved, have the vet examine for throat injury.

If the dog loses consciousness, lay them on their side, clear the airway if possible, and begin transport to the emergency clinic immediately.

Heatstroke

Heatstroke is rapidly life-threatening. Risk factors include hot environments, exercise in heat, lack of shade or water, and brachycephalic breeds (French Bulldog, Pug, English Bulldog) who cannot cool efficiently through panting. Signs: heavy panting, excessive drooling, unsteadiness, vomiting, collapse, abnormally red or pale gums.

Immediate cooling steps — then emergency vet:

1. Move the dog to shade or air conditioning immediately.
2. Apply cool (not ice cold) water to the body, especially underarms, groin, and paw pads.
3. Use a fan to increase evaporative cooling if available.
4. Offer small amounts of cool water if the dog is conscious and able to swallow.
5. Transport to the emergency vet — cooling is a stabilisation measure, not a cure. Heatstroke causes internal organ damage that requires professional assessment.

Do not use ice water or ice packs directly on skin — the extreme temperature causes blood vessels to constrict, slowing cooling and potentially causing cold-related injury.

Seizures

During a seizure: do not restrain the dog or put anything in their mouth. Dogs do not swallow their tongue. Move furniture away to prevent injury. Stay calm and time the seizure. Note the duration and any unusual behaviour before or after.

A single seizure lasting under 2 minutes in an otherwise healthy dog warrants a vet appointment (not necessarily emergency). Call your vet immediately if:

• The seizure lasts more than 2 minutes (status epilepticus — a medical emergency)
• Multiple seizures occur within 24 hours (cluster seizures)
• The dog does not return to normal within 30 minutes of the seizure ending
• It is the dog's first known seizure

After a seizure, dogs are often disoriented, confused, and may temporarily lose vision. Keep the environment quiet and dim, and do not crowd them.

Toxic ingestion

Do not wait for symptoms — many toxins cause delayed organ damage. Call the ASPCA Animal Poison Control Center (888-426-4435) or your vet immediately after suspected ingestion. Have the product name, active ingredients, and estimated quantity available.

Common household and food toxins for dogs:

• Xylitol — artificial sweetener in sugar-free gum, some peanut butters, dental products; causes severe hypoglycemia and liver failure in dogs
• Grapes and raisins — cause acute kidney failure; mechanism unknown; all amounts potentially dangerous
• Chocolate — theobromine toxicity; dark chocolate and baking chocolate are most dangerous; amounts matter
• NSAIDs (ibuprofen, naproxen) — cause gastrointestinal ulceration and kidney failure; common in human homes
• Rodenticides (rat poison) — multiple types; some cause bleeding disorders, others neurological damage; always bring the packaging
• Macadamia nuts — cause weakness, hyperthermia, tremors
• Onions and garlic — cause haemolytic anaemia; cooked, raw, or powdered forms all toxic

Frequently asked questions

What should every dog owner have in a first aid kit?

A basic canine first aid kit should include: gauze pads and rolls, self-adhesive bandage (vet wrap), medical tape, sterile saline or wound wash, blunt-tipped scissors, digital rectal thermometer, styptic powder (for nail bleeds), disposable gloves, a muzzle (even gentle dogs bite in pain), your vet's number and the nearest emergency vet's number, and the ASPCA Poison Control number (888-426-4435). Store it in a waterproof container and check expiry dates annually.

My dog ate something toxic — what should I do?

Call your vet or the ASPCA Animal Poison Control Center (888-426-4435) immediately — do not wait for symptoms to develop. Do not induce vomiting without professional guidance; in some toxin cases (caustics, petroleum products, certain medications) vomiting causes additional harm. Bring the packaging, label, or a photo of the substance to the vet. Common household toxins include: xylitol (sugar-free gum, some peanut butters), grapes and raisins, chocolate, ibuprofen, macadamia nuts, and rodent bait.

How do I know if my dog is in shock?

Signs of shock in dogs include: pale, grey, blue, or white gums (normal gums are pink and moist), rapid or weak pulse, rapid shallow breathing, extreme weakness or collapse, low body temperature, dilated pupils, and unresponsiveness. Shock requires immediate emergency vet treatment — keep the dog warm, calm, and horizontal, minimise handling, and get to an emergency clinic as fast as possible. Do not give food, water, or medication.

What is a normal temperature and heart rate for a dog?

Normal rectal temperature: 38.3–39.2°C (101–102.5°F). Temperatures above 39.4°C (103°F) are elevated; above 40.5°C (105°F) is a heat emergency. Normal resting heart rate: 60–140 beats per minute for most dogs (smaller dogs trend higher; large breeds trend lower). Normal resting respiratory rate: 15–30 breaths per minute. Knowing your dog's baseline makes it easier to identify abnormalities.

When is it an emergency vs something that can wait for a regular vet appointment?

Go to an emergency vet immediately for: difficulty breathing, collapse or inability to stand, suspected toxin ingestion, seizures, uncontrolled bleeding, suspected broken bones, eye injuries, pale or blue gums, bloated or distended abdomen, severe vomiting or diarrhea with blood, suspected heatstroke, or loss of consciousness. A regular appointment (within 24–48 hours) is appropriate for: minor limping without weight-bearing loss, small superficial wounds, mild digestive upset without blood, or ear scratching without discharge. When in doubt, call your vet — they can help you triage.
