Horse First Aid Kit: What to Pack, What to Do and When to Call a Vet

Most emergencies with horses give a short window. A deep cut, a colic attack or a horse that goes down in the heat will not wait while an owner searches for scissors, so a kit packed and checked in advance is part of owning one. The point is not to treat anything alone. The point is to keep the horse safe and calm, and to give the vet accurate information on the phone.

What goes into a horse first aid kit

A plastic tool box or a lidded tote works better than a bag, because it keeps contents dry and shows at a glance what is missing. Sort the contents into three groups and label them.

For assessment: a digital thermometer on a string with a clip, a stethoscope, a watch with a second hand, a small flashlight and a notebook with the horse’s normal vital signs written in it. Normal readings differ a little from horse to horse, which is why a written baseline helps.

For wounds and wraps: sterile saline for rinsing, clean gauze pads, non-stick pads, cotton roll, self-adhesive wrap, adhesive tape, blunt-nosed scissors and hemostats. Add a few disposable gloves and a clean towel. A roll of duct tape has a legitimate place here, since it holds a hoof boot or a poultice on a foot in a pinch.

For feet: a hoof pick, a hoof boot that fits, and a diaper or similar padding for a wrapped foot. The hoof care guide explains why a puncture in the sole needs the object left in place until the vet sees it.

Medication is a separate question. A kit should hold only what the vet has named, in the doses the vet has given, and anything that needs a prescription is the vet’s to supply. A pain reliever offered on a guess can mask the signs the vet needs to see, so the safe habit is to call first and follow instructions.

The baseline: vital signs worth knowing

Four numbers describe a horse at rest. Temperature is about 99 to 101°F. Pulse is roughly 28 to 44 beats a minute, found under the jaw or inside the elbow, and it can be counted for fifteen seconds and multiplied by four. Breathing is about 8 to 16 breaths a minute, counted by watching the flank. Gum color is pink and moist, and pressed with a thumb the spot should refill with color in about two seconds.

Take these on a day when the horse is well, at rest and in the shade, and write them down. When something goes wrong, a vet who hears that the horse’s resting pulse is usually 34 and today it is 60 has a much clearer picture than one who hears that the horse seems off. Practice a few times, because a nervous owner with a thermometer for the first time makes a nervous horse.

Wounds: what to do before the vet arrives

The first step is to keep the horse still and to stay safe. A hurt horse can strike or panic, and an owner with a bleeding leg and a loose horse has two problems. Tie or have a helper hold the horse, preferably in a quiet spot with firm footing.

Heavy bleeding gets steady pressure with clean gauze or cloth, held for several minutes without peeking. Rinse dirt from smaller wounds with saline or clean water. Do not pull out anything stuck in the wound, whether a stick, a nail or a piece of fence wire, and do not pour harsh disinfectant into it.

Some wounds always get a call. Those include anything near a joint or tendon, since those structures lie close to the surface on a horse’s lower leg and an infection in a joint is serious. Others are punctures, wounds near the eye or on the chest or belly, cuts that gape, wounds that bleed hard and wounds on a horse that is lame afterward. Tetanus matters too, and the vaccine schedule explains how that shot fits into the year.

Colic: the emergency that shows up as a bad afternoon

Colic is the word for abdominal pain, and it covers everything from a mild gas ache to a twisted bowel. A horse that paws, kicks at the belly, looks at its flank, lies down and gets up repeatedly, rolls, sweats without work or refuses feed is showing the standard signs.

The usual steps are to remove feed, keep the horse in a safe place where it cannot injure itself if it goes down, and call the vet at once with the temperature, pulse, breathing and gum color if possible. Walking a horse gently can ease a mild case, but a horse that is violent or trying to roll should be left alone with a helper nearby, since a rolling horse can hurt the person at its side. Medication goes in only on the vet’s say-so.

California adds sand colic and enteroliths to the list of causes. The page on enteroliths covers the stones that account for many of the state’s surgical cases, and it is worth reading before the first emergency, not during it.

Heat stress in California summers

Heat is a regular hazard from June through October, and the dangerous days are often the humid ones in the valleys and the first hot weekend of the year. A horse that works hard in the heat, has been recently transported, is overweight, is old or has not adapted to the climate is at higher risk.

Signs include rapid, shallow breathing that does not settle after a few minutes of rest, a high pulse, heavy sweating that runs down the legs, or the opposite, a horse that has stopped sweating at all, which can be a sign of a loss of the body’s cooling response. The horse may be dull, unsteady or reluctant to move, and its temperature can climb above 103°F.

First aid is cooling and a call to the vet. Move the horse to shade with airflow, run cool water over the big muscles of the neck, shoulders and hindquarters, scrape it off and keep applying more. Offer water in small amounts at a time. A hose is better than a bucket, and a fan helps in a stall. Do not ride on. The guide to California horse care covers the summer routine that keeps this from happening: work in the cool hours, clean troughs and shade.

Fire season and the go-bag

The same box that handles a wound handles a smoky evening. Fire season across most of the state turns the kit into part of an evacuation bag with halters carrying a phone number, lead ropes, copies of vaccine and coggins papers, a few days of feed and a bucket. Have two exits from the property planned, and practice loading a nervous horse in daylight. Many counties run volunteer animal-evacuation groups, but they cannot reach every barn, which is why owners are encouraged to have a plan of their own.

Looking after the kit

A kit that sits for two years is a kit with expired gauze and a dead thermometer battery. Check it twice a year, for example when the spring vaccines are given and again before fire season. Replace what was used, throw out anything past its date, and keep the vet’s number and the closest equine hospital’s number on the lid. Put a second copy in the trailer, since most injuries on the trail happen far from the barn.
