A photo your vet can use has three things a photo they cannot use is missing: something in frame for scale, a clean side-on angle, and a second wider shot showing where on the horse it is. For a lameness, a still image is close to useless and a video of the horse trotting in a straight line on a hard, level surface, filmed from the side and then from in front and behind, is what can actually be assessed. Send the photo with the facts attached: when it happened, what has changed since, the horse's temperature and pulse, and whether he is bearing weight. And a photo is never a substitute for a call when the horse is non-weight-bearing, when a wound is near a joint, or when there is heavy bleeding.
This page is about making a picture useful. It is not about deciding whether to call. That decision belongs to your veterinarian, and everything here is written to make their job possible rather than to replace it.
Why most photos of a wound are unusable
The problem is almost never the camera. It is four things, and they are all fixable in the ten seconds before you press the button.
No scale. A wound photographed on its own could be an inch across or six. A vet looking at a close-up cannot tell, and the size changes what they say. Put something of a known size in the frame beside the wound: a hoof pick, a tape measure, a coin, a glove. Anything, as long as you say what it is when you send it.
No context shot. A tight close-up of pink tissue tells a vet what the tissue looks like but not what it is. Take a second photo from further back showing the whole limb or the whole area, so the location is obvious without you having to describe it.
The wrong light. Direct sun makes hard shadows across a wound and washes out the surface. A flash fired close up does the same thing in reverse. Shade with even light, or an overcast day, is far better than a bright one. If you are in a stall, get the horse into the doorway rather than turning on the flash.
Shot from above. Almost every owner photographs a leg from standing height, looking down. That angle flattens everything. Crouch until the camera is level with the wound and shoot straight at it.
The three photos to take for a wound
Do these in order, and take more than one of each. Shoot from a safe position for the part of the horse you are near, and stop if he will not stand.
- The context shot. Whole limb or whole region, from the side, from a normal standing distance. This answers "where is it."
- The close-up with scale. Camera level with the wound, something of known size beside it, filling most of the frame. This answers "how big and what does it look like."
- The comparison shot. The same area on the opposite leg or the opposite side of the horse. This is the one nobody takes and it is often the most useful of the three, because it tells the vet what this particular horse's normal looks like.
Two more if you can get them safely:
- A shot along the limb from the front and from behind, which shows swelling that a side view hides.
- A shot showing whether he is weight-bearing, taken from directly in front or directly behind while he is standing square.
What to send with the photos
A picture with no facts attached makes your vet ask five questions before they can say anything. Send the answers with it.
- When you first saw it, and when you last saw the horse before that. The gap is the window in which it happened.
- What has changed since. Bigger, smaller, more or less lame, more or less swollen.
- Whether he is bearing weight, and whether he was when you first saw it.
- Temperature, pulse and respiration, if you can take them safely. Our guide to taking a horse's vital signs covers the how, and your horse's baseline covers why his own normal matters more than a chart.
- Whether there is a digital pulse, and whether it is stronger than on the other feet. That single observation changes what a vet thinks about a foot problem, and we set out how to find it in how to find and feel a digital pulse.
- What he has had, including any medication, and when.
If you keep a health log for the horse, this is exactly the moment it earns its keep. A log that records his resting temperature over months turns today's reading from a number into a comparison, which is the point we make in a per-horse health log your vet can actually use.
Lameness is video, not photographs
A still photograph of a lame horse shows a horse standing. It cannot show what a vet needs, which is how the horse moves.
Film him trotting, not walking. Most lameness is easier to see at a trot because the gait is regular and two-beat.
Straight line, hard and level ground. A rutted arena or deep footing changes the way a horse moves and makes a video hard to read.
Have someone lead him while you film, rather than filming a loose horse. Ask the handler to keep a loose lead so the head is free to move, because head movement is part of what the vet is watching.
Film three passes.
- From the side, filming the whole horse, as he trots past you.
- Coming straight toward you.
- Going straight away from you.
Hold the camera still and keep the whole horse in frame. Panning and zooming makes a video unusable. Stand still, let him come past, and film him for the whole length of the pass.
Film in landscape. Horses are wider than they are tall.
Do not film a horse trotting if he is non-weight-bearing or severely lame. That is not a video job, it is a phone call, and trotting a horse in that state can turn a serious problem into a worse one.
What a photograph cannot do
It cannot show depth. A puncture wound the size of a pinhole can be the most serious wound on this page, and it is the one that photographs as nothing at all. Say in the message if you think something has gone in rather than across.
It cannot show heat, and heat is one of the things a vet most wants to know. Feel the area and the opposite side, and say whether one is warmer.
It cannot show pain. Say what the horse does when you go near it.
It cannot show what is under a scab or inside a swelling, and it cannot tell a vet whether a joint or a tendon sheath is involved. That is why the wounds nearest a joint are the ones where the photo is the least useful part of the conversation.
FAQ
How do I take a photo of a wound my vet can actually use?
Get the camera level with the wound rather than shooting down at it, put something of a known size in the frame for scale, use even shade rather than direct sun or a close flash, and take a second wider shot so the location is obvious. Then take the same view of the opposite side for comparison.
Should I send a photo or a video of a lame horse?
Video, every time. Film him trotting in a straight line on hard, level ground, from the side, then coming toward you, then going away, holding the camera still with the whole horse in frame. A still photo of a lame horse shows a horse standing.
What should I write when I send my vet a photo?
When you first saw it, what has changed since, whether he is bearing weight, his temperature, pulse and respiration if you could take them safely, whether the digital pulse is stronger on that foot than the others, and anything he has been given and when.
Can I just send a photo instead of calling the vet out?
That is your veterinarian's call, not a decision this page can make for you. A photo helps them decide. It does not replace an examination, and there are cases, a horse who will not bear weight, a wound near a joint, heavy bleeding, or a puncture, where the photograph is the least important part of the conversation.
Why does my vet keep saying the photos are not clear?
Usually one of four things: no scale in frame, shot from standing height looking down, bright direct sun making hard shadows, or a close-up with no wider shot to place it on the horse. Fixing all four takes ten seconds.
Should I clean the wound before photographing it?
Ask your vet in the same message rather than deciding. What is on the wound is information, and cleaning it changes what they see. If they want it cleaned before they arrive, they will say so and they will say how.
Sources consulted, and how this page was built: no published veterinary protocol for owner photography was found while writing this, which is why nothing here is presented as a clinical standard. The photographic points are general imaging practice applied to a horse; the clinical points, that a puncture can be more serious than it looks, that heat and weight-bearing matter, and that a digital pulse is a key observation for a foot problem, are the observations veterinary references consistently ask owners for and are covered in this site's own vital signs and digital pulse pages, which carry their sources. This site is not written by a veterinarian and nothing here is a diagnosis, a dose or a treatment instruction. Every abnormal finding on this page has one action attached to it: call your vet.
