So plotting out what happens after he drives in and gets out of the car - might be called on to give a hand, or whoever he wanders up to for a chat says "Running late, can you do xxxx, talk later/talk as we work"
To fill in xxxx I am thinking that a relatively unskilled person, who is observant and used to animals in the form of sheep could be asked to do the following to help out:
Groom a placid horse – either working alongside the experienced person or has already had a lesson in how to do it.
Possibly, but only if the owner was sure the newcomer would be able/had some experience, as even a placid horse can be irritated by clumsy grooming.
Lead a placid horse up and down a walkway (but not a frisky one) or out to a field
As above. Many injuries to handlers come from a normally docile horse doing something unexpected, especially on the way out to the field.
Muck out empty stalls and put down feed and water for horses before they are brought in.
I'd say yes to water and hay, but no to feed as it's likely each horse will have a special feed (as in bucket feed -- hay is really forage and usually ad-lib unless the horses is obese or has underlying health issues).
Clean tack (but you wouldn't need a lot of tack at an animal hospital)
Maybe tidy up tack, e.g. put head collars away when they've been dropped in a heap by someone in a hurry, or coil up lunge lines and hang them up?
Questions on detail:
Food
In terms of putting out feed, hay could be put out at any time. But, any feed that is more desirable (like sheep nuts for sheep) that could attract birds or rodents – would you wait on that until just before the horse was brought in?
It's a good idea to wait until the horses are in to give them food, otherwise you create a habit of horses barging ahead because they associate their stable with instant yummy stuff. You could have the buckets all tacked, pre-prepared, either inside a feed bin or with lids on them outside stables. When we used to do livery for other people, we fed in the mornings and the owners would prepare feeds the night before and leave each one in a covered bucket (or hanging on a peg out of reach of rodents) outside each stable. The horses knew exactly what order they were fed in, but that didn't stop them trying to break down the stables doors when I was a little bit too slow on a cold winter morning!
Mood
If someone is in a bad mood, I'm assuming a horse would notice (sheep certainly do). Could you have an elderly, placid horse that wouldn't care if the person grooming it was in a bad mood, so long as they got their daily dose of brushing?
Horses do pick up on moods in their humans, but there's no predicting how it will affect any individual horse. My experience is that the more stressed you are, or the more you need to be finished quickly, the higher chance of a horse doing something really stupid or dangerous to itself or someone else. One of ours regularly tried to commit horse suicide whenever my daughter was getting ready to compete, even he wasn't the horse being prepared. His favourite trick was getting cast in his stable (imagine a sheep stuck on its back, but horse-sized, and jammed against a stable wall with thrashing hooves...)
Questions on grooming – or rather a sanity check on the things I vaguely remember plus a bit I've looked up – I remember doing it as having a brush in one hand and a curry comb in the other, you brush in the direction that the hair lies and use the comb to clean out the brush. However looking online here
Horse Grooming - Step By Step Guide | Horsemart
It is using the curry comb as the first stage on the horse to loosen everything, and doesn't mention cleaning the brush off on anything. And it is not brushing in the direction the hair lies until the final stage.
While doing the brushing, dust – skin cells, dried sweat and dried mud – comes off together with loose hairs. It all gets clogged on the brush and every so often you clean the brush off (I thought you used the curry comb for that but seem to have that wrong). You start at the top of the side of the horse, working backwards towards the tail, and then the next “stripe” along the side and then the next lower stripe. You get covered in fine dust/grime – as in your face, hands and clothes will have a fine coating of what you are brushing off and it may get in your nose. There is a particular smell to horses that will persist on you
I would agree with what you were taught, on the whole. There are two types of curry combs: the metal ones are used for cleaning other brushes and should never, ever be used on a horse; the plastic type can be used to shift particularly reluctant dried mud/sh*t before brushing with a softer brush. Some horses with sensitive skin can't even bear a plastic curry comb on them.
The way I do it is I start at the head with a soft brush and brush in the direction of hair growth. Most horses are quite itchy and many enjoy this bit, but think they can do it better than you if they rub their heads up and down against the brush. Then I start on one side and go down the neck, front of chest, front leg (outside), opposite front let (inside of leg), then along back and chest and under the tummy (some horses are a bit ticklish here, so watch out for those back feet trying to kick you, in case, as you said, you're actually a fly), working front to back. There's a bit where the hairs grow in funny directions on the side, just in front of the back leg. I usually follow hair direction there with the tip of the brush. Then top of bum, hind leg as for front legs, being careful to keep a hand on the back of the horse so you can move with it if it moves suddenly. Even feeling the muscles tense can be enough warning that you're about to get your foot squashed. If it's a mare, your feet are probably being targeted; if it's a gelding, it will almost certainly be accidental, but he'll stand there wondering why you're yelling, pummelling him with your fists and doing a one-legged war dance. I speak from experience. If it's a stallion, you should be especially wary of its feet, since they may well approach you at head-height.
If the horse keeps twitching a bit of its skin like a fly landed, that is a sensitive spot and best not brushed.
Yes, but usually a bit of reassurance and care will overcome this. If not, check for an injury or an infected fly-bite.
The horse may whisk its tail round and if you are near the rear end you can be swatted by it.
Yes, and they also fart in your face. I'm not completely convinced this is accidental, since they usually save it for when I'm plaiting their tails for a competition and can't escape the fumes. Which would knock out an elephant.
You will see motes of dust, glittering in the sunlight as you brush.
I'm allergic to horses, so usually everything is a blur of tears and sneezing, but you're probably right!
With less placid horses it's a good idea to tie the halter short so they can't turn and bite you and lengthen it when you are done grooming (the article doesn't mention length of rope, just being able to release it quickly).
If it's a less placid horse, the teeth are only a small part of your problem, but generally yes. We use a bit of thin, easily-broken string tied to a metal tie-ring in the wall, then we tie the horse to the string (never the metal ring) with a quick release knot. This means that if the horse panics, or slips on the concrete and falls (usually because it's playing silly buggers and deserves it, but still), the twine will snap and release the horse instead of the neck snapping when half a tonne+ falls over, hanging by said neck. Also, a horse can panic if it pulls back and meets an immovable force (the ring in the wall), and its response is to throw its full body weight into trying to escape this unseen enemy. They can injure themselves severely in this case. No one ever said horses were bright.
Some horses may try slamming you against the side wall of the stable by swinging their body
. Again, this is pretty rare. If it's a young horse that hasn't learned how to behave, or a competition horse buzzing with high energy food and nowhere to expend its excess energy, this can happen. I don't think they often do it on purpose, but I've been a victim of it, and my eyes popped a bit before I was able to poke it in the ribs and get it to move.
When you get the horse to lift its foot so you can check the frog, the horse may decide to lean on you.
Oh yes. They'll definitely try this one on if they think they can get away with it. There's a trick to stopping them. We had a foster donkey here for a while, and he used to sit down on the farrier until we fed him ginger nut biscuits. He'd have done anything for ginger nuts (apparently this goes for most donkeys). Our farrier told us he used to attend a donkey sanctuary, and they'd have to bring three of four strong lads along because one of the donkeys had discovered it could avoid a foot-trim by lying down. The farrier would lift the first foot. The donkey dropped like a stone. the farrier yelled, "get him, lads," or words to that effect and the big lads leapt on the donkey, rolled him on his back and held on to a foot each. the farrier then calmly trimmed each foot in turn upside-down. My farrier swears this is a true story, but you know what farriers are like...
Is the above correct?
Further question – if two of you are grooming a horse, one either side say, would it be OK for the two people to be chatting or would that upset some horses?
Chatting is good. The hum of voices chatting often settles horses. If they were arguing, however, that could unsettle the horse.
Questions on leading horses up and down for exercise – would that be done in a halter, or a bridle and bit? If the horse tosses its head high, can that pull a muscle in your arm?
Most horses, a head collar (halter) and lead rope. Some stronger horses (aka more lively), a bridle. If you're leading a horse you don't know well that looks lively, you'd probably put a bridle on, as long as you knew it had been broken to bridle (trained to wear and respond to a bridle with a bit in its mouth). If it's a stallion, you'd often use a special bit called a chiffney (see link) for extra control. And yes, a horse tossing its head high can wrench your shoulder (rubs own shoulder ruefully).
If you are leading a horse out from a shadowed barn to bright sunlight, could that cause the horse to jump back, rear, or in some other way protest the sudden bright light?
Only if they had an eye problem that caused the light to hurt their eyes, or if the barn was unusually dark, which wouldn't be a healthy environment for horses anyway. Horses are flight animals, so anything that has changed in their familiar environment can be seen as a threat (aka excuse to play silly buggers). For example, someone has parked the tractor in a different place, or a new horse box parked where no horse box has any right to be (in the horse's mind).
If yes, what is the answer – waiting in the doorway for the horse's eyes to adjust?
Sometimes our horses like to stop just inside the barn with their heads sticking out so they can check for enemies lurking outside, but I don't think that's to do with light because our barn is very bright inside, too. usually, they just follow happily, in the hope there might be something yummy at the end of the journey.
