How do you detail whether a horse is lame?

If a horse is lame... you can watch for limping... or not using one of the legs... however... if a horse is merely standing there... he will rest one of his back feet on his toe... whether you are kicking him, and giving him all the right commands to move, and he is standing there beside one of his feet not being used... that can mean he is lame...
There are diverse different techniques, and different people find different approaches effective for them. There are some things to look out for surrounded by both fore and hind limbs, and some that are unique to the fore/hind. Below I have outlined a screening of the more basic techniques for spotting lameness. There are plenty more depending on whether or not you lunge the horse, turn it in tight circles etc, but these are simple ones to look out for when trotting up. I other walk the horse towards and away from me once or twice depending on the expected severity of the lameness. I then trot towards and absent at least twice.

- Stride length: compare the stride length between left and right. The lame leg will usually own a shorter stride. This will not work if the horse is lame in both legs, however you may get the summary in this case that the overall strides are too short.
- Phases of stride length: look for the distance travelled by the limb both beforehand and after the weight-bearing phase of the stride. This will help when lame in both limbs, an example anyone laminitis - there is a long cranial phase (the phase between when the limb is in the upper air and when the horse is fully weight-bearing) and very short caudal phase (from fully weight-bearing to being lifted bad the ground again).
- Fetlock drop: compare how flexed the fetlock is between limbs when fully weight-bearing. In general a lame leg will have smaller amount flexion due to less weight being placed contained by the limb.
- Hoof sounds: listen to the rhythm of the hooves as they hit the floor.

- Head-nod: I find this one of the most useful basic technique. The horse's head naturally nods respectively time a fore limb is weight-bearing, and in a sound horse these nod will be equal in height. If a horse is lame on one leg the nod will be smaller and 'heigher' when the lame leg is weight-bearing, giving the impression the horse is 'nodding down' on the nouns leg. This is also very useful when lunging the horse as, if equally lame within both legs, it will usually nod down on the outside leg (as the inside one takes more weight).

- Hip drop: when watching a horse trot from at the back watch the motion of the tuber coxae (the point of hip). In a sound horse the motion of the two will be equal, in a lame horse the hip may any drop or hike (raise) depending on the nature of the lameness. The key is to look for asymmetry. (Vets can find this a short time unreliable and many prefer to look at the tuber sacrale insetad, the two mini peaks on the horse's croup, however this takes a incredibly keen eye as the movements are small).

All of the above techniques are during examination on the ground. In lay down to tell whether or not a horse is lame when ridden you need to look for imbalance, stiffness and reluctance to canter on one rein. Experienced riders will repeatedly be able to feel the horse being unlevel.

It cannot be stressed plenty that if you suspect your horse is lame please do not give it any bute or other pain reliever. You enjoy no idea what you are masking by doing this. In many cases nil untoward happens, which is why so many people do it. However, surrounded by the worst case scenario you could permanently incapacitate the horse. I have see a horse with a fracture be given bute (a fractured pedal bone will not always be as lame as you might expect) which was euthanased markedly soon after.
Usually you can see a limp. It can be more subtle. If you see a horse that is not reaching forward equally with the moved out and right legs, that can be a sign of lameness. Also, if the horse does not pick up the left and right legs evenly, that can also be a sign. Also, if here is uneveness in the rhythm of the gait, that can be a sign.
Have the horse trotted up in paw. If he's lame in front he will nod as the sound leg hits the ground, so the opposite one will be the one near the problem. If he's lame behind, the hip on the side that he is lame will rise when that leg hits the ground. Then you just have to find out where on earth he is lame. Start at the hoof and work up as the higher up the leg you go, the less credible it will be that you will find the lameness, most problems being found in the hoof, pastern or lower leg.
Answers:    Only one way to know 100% for sure is to call out your vet!!
first of all it will limp noticreabluy of late like a person if it is seriously lame. For smaller quantity obvious things trot it up on a hard surface - if it have a sore front leg it's head will jerk up when the sore leg hits the ground. If it is a hind leg them you will see the hip on the sore side looking higher as it trots than the other one. Also check legs for fry - this will point to the site of a problem if swelling or an actual wound is not noticeable. When you check for heat gross sure you run a hand down the opposite leg at like time to be able to differentiate between them.
watch it trot up, excessive leader nodding, favouring of one leg
Well some horses will be unmistakably lame so you'll see them struggle to walk and put weight on their legs, but in a smaller number obvious walk you might have to lunge them on both reins - study for a nod in the head - or a lack of match. The horse might be resisting movement.
If you're not sure its best to get someone that would know up to check and make certain though
They can loose.

You'll notice by the horse's shorter strides when he walks, even hesitancy to, scrutinize him when he does walk if it looks like he's limping or simply even looks funny when he does on whatever foot then take the hindmost of your hand and feel for any heat or warmness, don't hold your mitt there too long or else you'll start feeling your body warmth heating his fur. Usually in the summer it's easier to see any swelling but in the winter it's harder so be certain to feel. Side note: If he does feel melt (mind you it's not your own body heat and stay out of the sun as well) don't freak just bring some Veterinary Liniment at your local feed and farming store and apply it, you can wrap it if you choice but then you have to worry almost it being to tight and too loose, it will heal all indistinguishable though. Anyhoo hoped this helped. =D
I agree with everything Katie said, but wanted to add a few things.

Another track to tell if a horse is lame behind: at the trot the put money on hoof should land in same spot the front hoof just vanished.

How to detect lameness when you are on the horse is all about feel.
-If their gait feel more off balance going one direction (especially when you are making a tighter turn)
-I also find that if you agree to them trot on a loose rein it is easier to detect lameness
-If you think your horse may be off, you can usually discern the head come up a bit more when they step on the lame leg

*the above is for subtle lameness. If you cant tell when you horse is REALLY lame then you hold no business riding without the supervision of someone who can*

you should trot him up (you stipulation 2 people, one to lead the horse and one to observe)
if he is lame he will nod- jerk his head up on the leg that is lame.
hope i helped.
by seeing that it doesn't look like this
if you get the horse trot and see whether he/she is limping, also feel each leg for excess heat.
You can detect an unsoundness in various ways. The most explicit is limping--if the horse is not moving normally. This could be as extreme as the horse not being able to put any freight on one or more legs to just a tiny gimp that you only notice whether you look closely and know what to watch for (and are familiar with the horse's majority gait).

Other signs of an issue are heat, swelling, tenderness (when you touch it, the horse flinches or pulls away), and obvious injury (cuts, broken skin, etc.). Sometimes the horse might not be lame, but that doesn't expect he's all well. If you note anything phenomenal (any of the above as well as any difference in your horse's normal appearance or behavior), check it out further.

EDIT: Others own recommended different things. Someone suggested bute (phenylbutazone), which is basically a pain killer (like tylenol for people). It is great for relieving discomfort, but you have to be careful when using it. For one thing, whether it is used a lot, horses can develop ulcers and other issues and you'd hate to hold a lame horse be colicking as well (our vet instructed us to give Maalox, the human kind, to our horse who required several weeks of bute to bring down swelling). For another, whether it takes away all the strain, the horse may be TOO active and injure himself worse. Sometimes you don't want the horse to move around a lot--they'll end up making their injury worse than it already is.

Another person said that you can other tell when a horse is lame because they'll limp, and while that is true whether you consider lame to mean limping/obvious pain, a limp isn't other present in the case of an injury or other issue that should require rest. My sister's horse recently ripped adjectives the skin and a layer of muscle off of her forearm (about the size of my hand), yet she's really just lame (sometimes not at all). On the other hand, my horse will limp for three days after a routine farrier visit, but there's nothing really wrong with him and it wouldn't endanger him to ride him. Just be careful :).
get someone to trot the horse along level ground. study carefully how it steps and moves its feet.
If your horse is lame on one of its back legs it will throw his manager up when that leg touches the ground if your horse is lame on the front legs his head will go down. So once you know whether its the front or back then watch for the favour of the leg. But usually if you ride that horse alot you should be intuned with how its trots and walk so if you feel something different there is a well-mannered chance he will be lame.
basicly it will refuse to put wait on th hoof/hoofs its lame on
You will hold a limpy horsey when trotting and the head will bob up and down and is quite noticeable. Check for swelling and any warmness in the leg.
you can always tell when a horse is lame, as it will not want to move anywhere and when it does it shall move very slowly and clearly, as it will hurt to put pressure on that hoof.

it can be swollen, put your hand on the top of the hoof, and you will be able to feel boil through it.

if the horse is lame, i would put it on box rest. and bandage its front legs up to take the pressure bad the bones. You can also get Beaut from a vetinary practise that deals with equine services. this will relief to heal the pain and be a pain nouns
Lameness, by definition, is a symptomusually manifest as an altered gait pattern.
If it just sits there and does nought.
How do you come up with a question like this?
Rein stoppers. Help please :D?   What would be a polite pet name for horse that could meeting or be similar to Spirit?   Half Chaps...??   I only get a 15.33hh piebald horse, can you report me some interesting stuff something like them?
