Your dog first aid kit — what to actually keep

Pre-built dog first aid kits are mostly padding. Here's what genuinely belongs in one, and what to skip.

If you've ever bought a pre-made pet first aid kit, you'll know the feeling of opening it and finding it's mostly cotton wool, an instruction card, and seven plasters. The genuinely useful kit is shorter and cheaper than what's sold to you, and it doesn't include the things you might assume.

Below is the kit we'd actually keep at home and in the car. It's split into two categories: items that make a real difference in an emergency, and items that don't but are widely sold anyway.

What actually belongs in the kit

1. Your vet's number, the out-of-hours emergency vet's number, and the pet poison helpline number — written on paper. Phones run out of battery in emergencies. Print the numbers and put them on the inside of the kit lid. This single change has done more to speed up emergency calls than any product.

2. A muzzle that fits. Even a sweet-natured dog will bite when in pain or scared. A soft muzzle is essential for safely examining or moving an injured dog. Cheap, light, takes no space — buy one before you need it. Don't use it on a dog that's vomiting.

3. A self-adhesive bandage (Vetwrap or similar). Sticks to itself, not to fur. This is the single most useful wound-management item for dogs. Conventional bandages that stick to skin are useless on a dog.

4. Sterile gauze pads and a roll of gauze. For pressure on bleeding wounds before you reach the vet.

5. A digital rectal thermometer. Normal dog temperature is 100.5–102.5°F (38.1–39.2°C). Anything above 103°F (39.4°C) is a fever; above 105°F (40.5°C) is heatstroke territory. Knowing the number while on the phone to the vet matters.

6. Saline solution (or a sterile saline pod set). For flushing eyes after grass-seed exposure or chemical splashes, and for cleaning surface wounds.

7. Tweezers and a tick remover. Different tools, both needed. Tweezers for splinters, the hooked tick remover for ticks. Don't use tweezers on ticks — you'll squeeze the body and increase pathogen transfer.

8. A blanket or large towel. Dual-purpose: for warmth in shock, or as a stretcher for a large injured dog.

9. A small torch / flashlight. Mouth checks, ear checks, pad checks at night. Phone torches work fine but having a dedicated one in the kit means you don't need both hands.

10. Photographs of your dog and copies of vaccination records. If your dog is ever lost or attacked, both speed things up. A printed photo and a folded photocopy of the vax record live in the kit.

What to skip — even though it's in most kits

Hydrogen peroxide. Old advice was to use it to induce vomiting. Current vet guidance has moved away from this, especially without veterinary instruction — it can cause severe stomach lining damage, and inducing vomiting is the wrong move for some toxins (caustics, sharp objects, anything already absorbed). Always call the vet first.

Antiseptic creams marketed for pets. Most are a marketing exercise around ingredients that are already in your bathroom cabinet. A dab of dilute chlorhexidine solution on a cotton pad is what most vets actually use.

Activated charcoal tablets. Useful in emergency vet treatment, useless in home administration without dose calculation. Don't try this at home.

Aspirin or human painkillers. Never give. Paracetamol is fatal at small doses. Ibuprofen damages the kidneys and gut lining. The phrase "a small dose of children's aspirin" appears on dodgy advice forums and should be ignored — there is no safe dose without vet supervision.

Cotton balls and cotton wool by the bagful. Dogs eat them, they cause obstructions, and they shed fibres into wounds. Use gauze.

The car version of the kit

Keep a duplicate (smaller) kit in the car if you walk your dog away from home regularly. The contents to prioritise: bandages, muzzle, the printed vet numbers, a bottle of clean drinking water, and a foil emergency blanket (cheap, takes no space, useful for shock).

Don't leave the kit in direct sun all summer. Saline pods and adhesive bandages degrade in heat. Keep it in the boot/trunk, ideally in an insulated bag.
