What to Put in a Dog First Aid Kit (And How to Use It)

A first aid kit does not replace a vet. Its job is to buy time, control bleeding, and stop a bad situation getting worse on the way to professional help.

The kit

Wound care

• Sterile gauze swabs, several sizes
• Non-adherent sterile dressings
• Conforming bandage (the stretchy layer)
• Self-adhesive cohesive bandage — the kind that sticks to itself, not to fur
• Micropore or zinc oxide tape
• Sterile saline pods for flushing wounds and eyes
• Antiseptic solution — dilute chlorhexidine or povidone-iodine
• Blunt-ended scissors
• Tweezers
• A tick hook
• Disposable gloves

General

• A digital thermometer (rectal) and lubricant
• A foil blanket
• A clean towel and a spare blanket
• A muzzle that fits your dog — a frightened, painful dog may bite, including you
• A slip lead
• Your vet’s number, your out-of-hours vet’s number, and an animal poison line, written down as well as in your phone
• A copy of your dog’s medical history and any regular medication
• A card with your dog’s weight on it

Not in the kit

• Human painkillers of any kind
• Hydrogen peroxide for cleaning wounds — it damages tissue
• Cotton wool directly on a wound — fibres stick
• Anything you have not been shown how to use

Know your dog’s normals

Take these when your dog is healthy, and write them down. Abnormal only means something if you know normal.

• Temperature: 38.3 to 39.2°C (101 to 102.5°F)
• Heart rate: 60 to 140 bpm depending on size — small dogs faster
• Breathing: 10 to 30 breaths per minute at rest
• Gums: moist, pink. Press until pale; colour should return in under two seconds

The four that matter most

Severe bleeding

1. Apply firm direct pressure with gauze or a clean cloth
2. Do not lift the dressing to look. If it soaks through, add more on top
3. Elevate the limb if you can do so without causing pain
4. Bandage firmly over the pad and go to the vet

Do not use a tourniquet unless a vet has instructed you to. They cause severe damage when applied wrongly.

Heatstroke

This is the emergency where the first five minutes genuinely change the outcome.

Signs: frantic panting, drooling, bright red gums, vomiting, wobbliness, collapse.

1. Move to shade and out of the car
2. Pour cool — not ice-cold — water over the whole body, continuously. Current evidence favours aggressive cooling, including immersion in cool water where possible
3. Airflow: a fan, or an open window in a moving car
4. Offer small amounts of water if conscious
5. Go to the vet immediately, cooling on the way. Internal damage happens even in dogs who seem to recover

Do not cover the dog with wet towels and leave them — that traps heat.

Choking

Signs: pawing at the mouth, distress, gagging, blue gums, no air moving.

1. Open the mouth and look. If you can see the object and grasp it safely, remove it
2. Do not blindly sweep with your fingers — you push it further
3. For a small dog: hold them upside down with the back legs up and give five firm blows between the shoulder blades
4. For a large dog: lift the back legs like a wheelbarrow and give five blows between the shoulder blades
5. If that fails, a canine Heimlich — sharp inward and upward pressure just below the ribcage
6. Any choking dog needs a vet check afterwards, even if the object comes out

Suspected poisoning

1. Remove the dog from the source and take the packaging
2. Ring your vet or a poison line immediately. Have your dog’s weight ready
3. Do not induce vomiting unless instructed — it causes more damage with caustic substances and sharp objects, and home methods like salt water are dangerous
4. Do not give milk, bread or anything else “to absorb it”

Other common situations

Cut paw pad. Flush with saline, apply a non-stick dressing, bandage including the whole foot, and go to the vet. Pads bleed heavily and heal slowly.

Grass seed in a paw or ear. Sudden lameness with licking between the toes, or violent head shaking. Do not dig for it. Vet, same day — they migrate.

Insect sting. Remove a visible bee sting by scraping sideways rather than pinching. Cold compress. Watch for facial swelling, hives, vomiting or breathing difficulty, which means immediate vet.

Seizure. Do not restrain the dog and do not put anything in their mouth. Move furniture away, dim the lights, note the time. Any seizure over five minutes, or repeated seizures, is an emergency.

Suspected fracture. Do not splint. Support the dog on a firm surface — a board, a rigid bag — and transport carefully. Muzzle first.

Handling an injured dog

Pain makes dogs bite, including dogs who have never bitten anyone. That is not a character flaw; it is a reflex.

• Muzzle first for any painful injury, unless the dog is vomiting, struggling to breathe, or overheating
• Approach slowly, speak calmly, get to their level
• Move a large dog on a blanket used as a stretcher, with two people
• Support the whole body rather than lifting under the abdomen

Practise putting the muzzle on at home, with food, when nothing is wrong. A dog who has never worn one will fight it exactly when you cannot afford the delay.

Take a course

Reading about canine first aid is not the same as having done it. Many organisations run one-day practical courses covering bandaging, CPR and emergency handling, and they are genuinely worth a Saturday.

The single most useful thing on this page remains the simplest: have your emergency vet’s number where you can find it in thirty seconds, and know how long it takes to get there.
