# A first-aid kit for a dog: what belongs in it and what does not

A kit is not for treating an injury. It is for controlling bleeding, protecting a wound and getting the dog to a practice without making anything worse.

*An open first-aid box on a table with bandages, gauze, scissors and a thermometer laid out beside it*

## The short answer

- The purpose of a kit is stabilise and transport. Nothing in it treats a condition, and an item that encourages you to stay home is a liability.
- A soft muzzle belongs at the top of the box. A dog in pain bites the person it loves most, and a bitten owner cannot drive it anywhere.
- Sterile saline is the most useful liquid in the kit — for flushing eyes and wounds — and it replaces every antiseptic people are tempted to include.
- Do not stock human painkillers, and do not stock hydrogen peroxide as a routine 'make it vomit' item. Both cause harm on their own.
- Two pieces of paper matter more than most of the contents: the out-of-hours number, and a current list of the dog's medication and conditions.

Most first-aid kits sold for dogs contain a scattering of useful items and several that should not be there. The problem is not the packaging — it is the underlying idea, which is that a kit is for treating something.

It is not. **A dog first-aid kit exists to control bleeding, protect a wound from further contamination, keep the animal warm, and get it to a practice without anyone else getting hurt.** Everything in the box should serve one of those four aims, and anything that tempts you to manage a situation at home is working against the kit’s purpose.

## What earns its place

***The right-hand column is the more useful one.** Most of what goes wrong with home first aid is not a missing item but a present one — something that delayed the journey, damaged the wound, or poisoned the animal. Free to reuse with a link to this page.*

### The muzzle, and why it is first

A dog in severe pain may bite. It will bite the person handling the painful part, which is usually the person it is most attached to, and it means nothing about the dog’s temperament.

The consequence is practical rather than sentimental: a bitten handler cannot lift, restrain or drive. A soft fabric muzzle applied calmly before anything is examined removes that risk for both of you.

Two absolute exceptions. **Never muzzle a dog that is vomiting, struggling to breathe, or has an injury to the face, mouth or airway.** In those situations a muzzle can kill. Use a towel over the head, a second person, or simply do less.

### Saline, and why it replaces the antiseptics

Sterile saline pods are the most useful liquid in the box. They flush grit and debris out of a wound, they rinse an irritant out of an eye, and they cool a burn — and none of that requires anything to be applied.

Everything people reach for instead is a downgrade. Alcohol wipes damage exposed tissue and hurt. Concentrated antiseptics can be irritant and are frequently used at the wrong dilution. Human antiseptic and antibiotic creams are formulated for skin that is not going to be licked off, and a dog removes and swallows them within minutes.

### Dressings and bandages, used as a covering

The aim is to keep a wound clean during the journey — not to treat it.

Non-adherent dressings sit against the wound without sticking to it. Conforming bandage holds them in place. Self-adhesive bandage goes over the top, and it is the item most likely to be misused: it stretches as it is applied and tightens further afterwards.

**A bandage that is too tight is a worse injury than the one it covers.** Apply loosely enough to slide a finger underneath, and check the limb below it: if it becomes cold or swollen, or the dog starts chewing at it, take the bandage off. Tourniquets belong to the rarest catastrophic bleeds and are far more often applied wrongly than usefully — direct pressure with a gauze pad, held firmly and not lifted to peek, controls the great majority of bleeding.

*What each item in the kit is for. Every row maps to one of the four aims — control bleeding, protect the wound, keep the dog warm, get everyone there safely.*

| Item | Its one job |
| --- | --- |
| Soft muzzle, spare slip lead | Stops a second casualty and keeps control of the dog outside the car |
| Disposable gloves | Keeps a contaminated wound from getting worse and protects you |
| Sterile gauze swabs | Direct pressure on bleeding; nothing else controls it as well |
| Non-adherent dressings | Covers the wound without sticking to the exposed surface |
| Conforming and self-adhesive bandage | Holds the dressing in place for the journey only |
| Blunt-ended scissors | Cuts bandage and clips hair away from a wound edge without stabbing |
| Tweezers, tick-removal tool | Removes a tick whole; a splinter that is clearly superficial |
| Digital thermometer, lubricant | Supplies the number the practice will ask for on the phone |
| Sterile saline pods | Flushes eyes and wounds; replaces every antiseptic |
| Foil blanket, clean towel | Prevents heat loss; the towel doubles as a stretcher and a restraint |
| Card of numbers, medication list | Removes the two things people fumble under stress |

### Cotton wool is not a dressing

It shreds, the fibres embed in the wound surface, and removing them later hurts and prolongs healing. It has a role as padding under a bandage, over a dressing, and never in direct contact with an open wound.

## Why the excluded items are excluded

**Human painkillers.** Paracetamol, ibuprofen, naproxen and aspirin each fail differently in dogs — liver, gut, kidney, clotting — and the reasoning is set out in [can I give my dog human painkillers](https://galen.vet/journal/can-i-give-my-dog-human-painkillers/). Their presence in a kit is worse than useless, because a kit implies its contents are appropriate.

**Hydrogen peroxide.** Included in many commercial kits as a vomiting agent. Inducing vomiting is the wrong action for anything sharp, corrosive or petroleum-based, and it is dangerous in a drowsy, seizing or dyspnoeic dog. Peroxide itself irritates the stomach and has caused serious injury when repeated. Whether to empty a stomach is a telephone decision with a practice or a poison service, and if they advise it, they will tell you what to use.

**Leftover prescription medicines.** A course dispensed for a different dog, a different condition or a different month is not a first-aid item. Store current medication separately, with its label intact.

## The two pieces of paper

These matter more than most of the contents and are the part people leave out.

**A card of numbers.** The practice, its out-of-hours arrangement — which in many areas is a different provider at a different address — and an animal poison service. Written down, not only in a phone, and in the kit as well as on the fridge.

**A current summary of the dog.** Age, weight, microchip number, known conditions, allergies and every medication with its strength. Handing that over on arrival saves several minutes at exactly the point where minutes matter, and it removes the chance of misremembering a strength under stress — the units on those labels are the subject of [IU, mg/mL and percent](https://galen.vet/journal/veterinary-drug-units-iu-mg-ml-percent/), and a photograph of each packet in your phone is a reasonable backup.

## Using it: the order of operations

1. **Make the scene safe** — traffic, another dog, whatever caused the injury.

2. **Muzzle**, unless one of the exceptions applies.

3. **Assess breathing and consciousness first.** Everything else waits behind these.

4. **Control obvious bleeding** with direct pressure through a gauze pad. Add more on top rather than lifting to look.

5. **Telephone the practice** and say you are coming. They can prepare; you can also be redirected to a better-equipped centre.

6. **Cover, warm, transport.** A foil blanket over a towel; a flat rigid surface if a spinal injury is possible; two people to lift a large dog.

7. **Take the evidence** — packaging, the plant, what is left of the object.

## Keeping it usable

Check it twice a year. Saline pods and sterile dressings expire and packaging gets damaged in a rummaged box; thermometer batteries die unnoticed; phone numbers change; and the medication list goes stale fastest of all.

Keep a second, smaller kit in the car, since a large share of injuries happen on walks and away from home. And keep both out of the dog’s reach — a kit contains several things a bored dog should not eat, which is its own kind of irony.

## Bottom line

A dog first-aid kit is for stabilising and transporting, not for treating. The contents that earn their place are a soft muzzle and spare lead, gloves, sterile gauze and non-adherent dressings, conforming and self-adhesive bandage, tape, blunt scissors, tweezers and a tick tool, a digital thermometer, sterile saline, a foil blanket and a towel, plus a card of numbers and a current summary of the dog. Leave out human painkillers, routine hydrogen peroxide, human antiseptic creams, cotton wool for direct contact, alcohol wipes and leftover prescriptions — each of those is capable of making things worse. Muzzle first unless the dog is vomiting, struggling to breathe or has a facial injury; flush with saline rather than applying anything; bandage loosely and only for the journey; and phone ahead.

## Questions readers ask

What should a dog first-aid kit contain?

A soft muzzle and a spare slip lead; disposable gloves; sterile gauze swabs and non-adherent dressings; conforming and self-adhesive bandage; adhesive tape; blunt-ended scissors; tweezers and a tick-removal tool; a digital thermometer with water-based lubricant; sterile saline pods for flushing; a foil blanket; a clean towel or blanket that can serve as a stretcher; and a card with the practice number, the out-of-hours number, an animal poison service number and the dog's details. That is the working set — anything beyond it is refinement.

Why is a muzzle the first item?

Because pain overrides temperament. A dog with a fracture, a deep wound or severe abdominal pain may bite when the injured area is touched, and it is not a comment on the dog or on your relationship with it. A bitten handler is a second casualty who then cannot drive, restrain or carry. Use a soft fabric muzzle, introduce it calmly, and never muzzle a dog that is vomiting, struggling to breathe, or has a facial or airway injury.

Should I keep hydrogen peroxide to make my dog vomit?

Not as a default. Inducing vomiting is the wrong action for several of the most common ingestions — anything sharp, anything corrosive, and anything petroleum-based — and it is dangerous in a dog that is drowsy, seizing or struggling to breathe. Hydrogen peroxide also causes gastric irritation of its own and has caused serious injury when given repeatedly. Whether to empty the stomach, and how, is a decision made on the telephone with a practice or a poison service, not in advance.

Can I put antiseptic cream on a dog's wound?

Better not. Human antiseptic and antibiotic creams are formulated for skin that will not be licked, and a dog removes them within minutes and swallows them. Some contain ingredients that are irritant or toxic to dogs. The useful thing to do with a wound at home is to flush it with sterile saline, cover it with a non-adherent dressing to keep it clean, and go — everything else is a veterinary decision made after the wound has been assessed for depth and contamination.

How tightly should a bandage be applied?

Loosely enough to slide a finger under, and only as a temporary covering for transport. A bandage applied too tightly on a limb cuts off circulation and can cause damage far worse than the original wound, and it is easy to do with a self-adhesive bandage, which tightens as it is stretched. If a limb below a bandage becomes cold, swollen or the dog starts to chew at it, remove the bandage. Tourniquets are for the rarest of catastrophic bleeds and are more likely to be applied wrongly than usefully.

How should the kit be maintained?

Check it twice a year. Replace anything expired, particularly saline pods and dressings whose sterile packaging has been opened or damaged; replace the batteries in the thermometer and any torch; and update the medication list and the phone numbers. Keep a second smaller kit in the car, because a good proportion of injuries happen away from home, and keep both out of the dog's reach — a first-aid kit contains several things that should not be eaten.

Galen publishes reference material on veterinary medicines. It describes how
products are labelled, stored and classified; it does not tell you what to give an
animal, in what amount, or for how long. Those decisions belong to a veterinarian
who has examined the animal, working from the manufacturer's labelling for the
exact product in front of them. Where national rules apply — to prescribing,
residues in food, or reporting a suspected reaction — the authority in your own
country is the one that governs.
