The 12 emergencies
Bleeding wound
Do
- ✓Apply firm direct pressure with a clean cloth for 3–5 minutes without lifting to check
- ✓Elevate the wound if on a limb and if the pet allows it
- ✓If pressure controls it, get to a vet for cleaning and possible sutures
Do not
- ×Do not apply a tourniquet unless trained — it can cause limb loss
- ×Do not pour hydrogen peroxide on the wound (delays healing)
Choking
Do
- ✓Look in the mouth in good light. If you see the object and can grasp it safely, remove it
- ✓For small dogs and cats, hold them with the head pointing down and give 4–5 firm taps between the shoulder blades
- ✓For larger dogs, modified Heimlich: stand behind, place hands just below the ribcage, give 4–5 quick upward thrusts
Do not
- ×Do not blindly stick fingers in the throat (you can push the object deeper or get bitten)
- ×Do not give water to a choking pet
Heatstroke
Do
- ✓Move to shade or air-conditioned space immediately
- ✓Apply cool (not ice-cold) water to belly, paws, armpits, groin
- ✓Offer small amounts of cool water if conscious
- ✓Drive to emergency vet — heatstroke kills via organ damage hours later even after cooling
Do not
- ×Do not use ice or ice water (causes vasoconstriction, traps heat)
- ×Do not assume they are OK after cooling — internal damage is delayed
Suspected poisoning
Do
- ✓Identify the substance, amount, and time of ingestion
- ✓Call your vet or pet poison line (US: ASPCA 888-426-4435, Pet Poison 855-764-7661)
- ✓Bring the packaging or substance to the vet
Do not
- ×Do not induce vomiting unless instructed by a vet (some substances cause more damage on the way back up)
- ×Do not give milk, oil, or 'home remedies' — they can worsen absorption
Seizure
Do
- ✓Move objects away so the pet does not hurt themselves
- ✓Time the seizure (most last 30 seconds to 2 minutes)
- ✓Speak softly, dim the lights
- ✓Take to the vet after the seizure ends; emergency vet if it lasts >5 minutes or repeats
Do not
- ×Do not put hands near the mouth (myth — pets do not swallow their tongues)
- ×Do not restrain the body forcefully
Suspected broken bone
Do
- ✓Muzzle the pet gently (pain causes biting)
- ✓Carry on a flat surface (board, towel) to minimize movement
- ✓Take to vet for X-rays
Do not
- ×Do not try to set the bone yourself
- ×Do not give human pain medication (many are toxic to pets)
Burn
Do
- ✓Run cool (not cold) water over the burn for 5–10 minutes
- ✓Cover loosely with a damp cloth
- ✓Take to vet for assessment
Do not
- ×Do not apply butter, oil, ointments, or ice
- ×Do not pop blisters
Hypothermia (cold exposure)
Do
- ✓Move to warm space
- ✓Wrap in warm (body-temperature) towels or blankets
- ✓Warm hot water bottle wrapped in cloth against the body
- ✓Take to vet — cardiac arrest can occur during rewarming
Do not
- ×Do not use direct heat (hair dryer, heating pad on high) — burns and shock
- ×Do not submerge in warm water
Allergic reaction (swelling, hives)
Do
- ✓Note the timing and possible trigger
- ✓If face/throat swelling, go to emergency vet immediately (airway risk)
- ✓For mild reactions, your vet may advise diphenhydramine (Benadryl) at a specific dose — call first
Do not
- ×Do not give human Benadryl without confirming the dose with your vet
- ×Do not give pseudoephedrine or any decongestant (toxic to pets)
Eye injury
Do
- ✓Prevent rubbing or pawing with an Elizabethan collar if available
- ✓Rinse gently with sterile saline if foreign object visible
- ✓Get to vet within 24 hours; same day for any visible damage
Do not
- ×Do not use human eye drops without vet guidance
- ×Do not try to remove embedded objects
Snake bite
Do
- ✓Keep the pet still and calm (less movement slows venom spread)
- ✓Identify the snake from a safe distance (color, pattern, photo)
- ✓Drive to nearest emergency vet immediately
Do not
- ×Do not cut the wound or try to suck out venom
- ×Do not apply ice or tourniquet
- ×Do not give alcohol
Cardiac arrest (CPR)
Do
- ✓Check for breathing and pulse (inside the thigh)
- ✓For small dogs/cats: place pet on their right side, compress chest with one hand at ~100–120 compressions/minute
- ✓For larger dogs: two-hand compression over widest part of the ribcage
- ✓Give a rescue breath into the nose every 30 compressions (mouth held closed)
- ✓Get to emergency vet while continuing CPR
Do not
- ×Do not delay transport to keep doing CPR alone — call ahead
- ×Do not give up at 5 minutes; continue until vet care
Frequently asked questions
What should be in a pet first aid kit?
Sterile gauze pads and rolled gauze, non-stick wound dressing, self-adhesive bandage (Vetwrap), blunt-tip scissors, tweezers, digital thermometer (rectal use), sterile saline (for eye/wound rinsing), hydrogen peroxide 3% (only for inducing vomiting if vet-directed), instant cold pack, soft muzzle, Elizabethan collar (cone), tick remover, emergency contact card with your vet and pet poison line, your pet's vaccination record. Store in a labeled container.
When should I induce vomiting?
Only when explicitly told to by a veterinarian or a pet poison line. Some substances (caustics, petroleum products, sharp objects) cause more damage on the way back up. Never induce vomiting in an unconscious or seizing pet. Hydrogen peroxide is the household method when authorized; dose is approximately 1 mL/kg, repeated once if no vomiting in 15 minutes.
Can I give my dog human pain medication?
Generally no. Ibuprofen, naproxen, acetaminophen, and aspirin can be toxic to dogs and cats. Cats are particularly sensitive to acetaminophen (Tylenol) — even one regular tablet can be fatal. Always check with your vet before giving any human medication.
How do I take a dog's or cat's pulse?
Femoral artery, inside the upper thigh. Press gently and count for 15 seconds, multiply by 4. Normal for dogs: 60–140 beats per minute depending on size (small breeds higher). Normal for cats: 140–220 beats per minute. Practice on a healthy pet so you can recognize abnormal in an emergency.
Is pet first aid a substitute for the vet?
No. First aid stabilizes the pet for the next 5–30 minutes so you can get to a vet. Every emergency in this guide ends with 'vet visit' or 'emergency vet.' First aid buys time; the vet fixes the problem. Omelo's free symptom checker helps you decide which level of vet care is needed in 30 seconds.
