Building and maintaining a pet first aid kit

A good kit solves three separate problems, and it pays to keep them separate because each needs different material. The first is protection: keeping a wound from contamination, keeping a frightened animal from biting the person helping, keeping an unstable limb still during transport. The second is measurement: gathering two or three objective numbers to report on the phone, because the phrase he is unwell tells the clinic nothing about whether to prepare a room. The third is documentation: making sure the animal's identity and clinical history arrive at the clinic with the animal.

• Protect: stop things getting worse on the way from home to the clinic.
• Measure: collect a few objective figures and write down the time you took them.
• Document: send identity, current treatments and contacts along with the animal.

Thinking in categories rather than in individual items avoids two classic mistakes: buying five things that do the same job, and forgetting an entire function. Each category in the table gets its own clear bag, so in an emergency you reach for a bag rather than hunting for a loose item at the bottom of the box.

1. 1

   Choose the container and make it unmistakable

   You want something rigid, resealable and a colour that looks like nothing else in the house. Do not use the same box as the human medicines: in an emergency people open whichever box they reach first, and mixing the two is the fastest route to a mistake.

2. 2

   Split the material into bags by category

   One clear bag per category from the table, closed and labelled on the front with a marker. Whoever opens the kit should see where the gauze is within three seconds, without tipping everything onto the floor.

3. 3

   Write the animal's data sheet on a single page

   Name, species, breed, date of birth, weight with the date it was taken, microchip number, chronic conditions, current treatments, known reactions. One page, printed, inside a plastic sleeve. A weight without a date is useless, because a figure from two years ago does not describe the animal in front of you.

4. 4

   Add the contacts to the same page

   Your regular clinic with its hours, the nearest out of hours facility with the address written in full, the poison control service for your country where one exists, and the neighbour who holds your keys. Write them even though they are in your phone: in an emergency the phone is for calling, not for searching.

5. 5

   Fit and rehearse the muzzle while the animal is well

   A muzzle bought and never tried is useless. Measure the muzzle, choose a soft model that still allows the mouth to open, and get the animal used to it in short sessions with a treat. Never apply one to an animal that is vomiting, struggling to breathe, or already short of breath because of a flat face.

6. 6

   Put what you know how to use on top

   The top layer holds gloves, gauze, cohesive bandage and saline, the four things that cover most real incidents. Everything else sits underneath. A kit ordered by frequency of use empties in the right sequence.

7. 7

   Write the build date inside the lid

   Write the date you closed the kit and the date of the next check straight onto the inside of the lid with the marker. It is the one place where no label peels off and where everyone reads it the moment they open the box.

8. 8

   Run a cold rehearsal against the clock

   Ask someone to time you while you find gloves, gauze and the data sheet. If it takes more than a minute the kit is badly organised and needs rebuilding now, not during the emergency. Repeat the drill with whoever is home when you are not.

One kit does not cover every setting: the home one can be complete, the car one has to survive heat, and the walking one has to fit in a pocket or you will never carry it. The table shows how the same base list is spread across the three.

An unchecked kit ages quietly: the cohesive bandage hardens, the thermometer battery dies, the weight on the data sheet is still the one from two years ago and the clinic number changes without telling anyone. A full check takes ten minutes and belongs in the calendar, not in your memory.

Half the harm done in an emergency comes from material added to the kit with the best of intentions. This is the part of the guide worth reading twice, because it takes things out instead of adding them.

• Medicines from the household cabinet: several molecules common in family homes are toxic to dogs and cats, and none should be given on your own initiative.
• Leftovers from previous courses, whether your animal's or another's: a prescription belongs to that case, that date and that animal.
• Hydrogen peroxide used as a routine wound disinfectant: it damages healing tissue, and its use to induce vomiting is decided only on the phone with a vet, never alone.
• Alcohol and coloured disinfectants on open wounds: they sting and stain the tissue, making assessment harder for whoever examines the animal later.
• Improvised tourniquets: they cut off circulation to the limb and without training cause more harm than the bleeding they are meant to stop.
• Cotton wool against the wound surface: it leaves fibres that later have to be removed under sedation.
• Tools for pulling out foreign bodies: anything visible in the throat, the eye or embedded in the chest stays where it is, because it is often the only thing plugging the injury.
