Assemble a pet first-aid kit: gauze, non-stick bandages, adhesive tape, blunt scissors, tweezers, a digital thermometer, saline, gloves, and your vet's and the nearest emergency clinic's numbers saved in your phone.
Know the signs of an emergency: difficulty breathing, pale gums, prolonged seizures, collapse, bloating in large deep-chested dogs, suspected toxin ingestion, or uncontrolled bleeding. These mean "go now," not "wait and see."
For bleeding, apply firm, direct pressure with a clean cloth. For choking, look in the mouth only if you can see the object without pushing it deeper; otherwise head to a clinic. Never give human medications without veterinary guidance.
Learn pet CPR basics from a certified course before you need them. Chest compressions differ by size, and rescue breathing requires a proper seal over the nose and closed mouth. Practice on a stuffed model, not your pet.
Finally, keep a muzzle in the kit — even gentle pets may bite when in pain. A makeshift muzzle from a leash or gauze can protect you while you help them.
