It is so important to do the little things to keep your horse sound and mentally and physically fit no matter what his job is. Far too easy is it to get lost in the rushing and scheduling and riding that consumes us on a daily basis. But it's those tiny tasks, many that take only seconds, that collectively add up to a well-managed horse. This is what makes a horse(wo)man, not just a rider.
Take the time to palpate your horse's neck, back and haunches before and after a ride to look for tender spots. Just running your fingers down the big muscles with medium pressure can tell you a lot.
Take the time to run your hands down each leg so you know if that knot is new or old.
Take the time to lay a palm on each hoof as you pick them to check the temperature.
Take the time to wiggle each shoe to check for tightness when you lift his feet.
Take the time to really notice the colour, shape and texture of his frog and sole so you know if they change.
Take the time to run your fingers up the back of his pasterns to check for fungus like scratches.
Take the time to take him out on a hack to condition him on hills and uneven ground at the walk and trot, getting him fit the RIGHT way. Don't get trapped in the sandbox.
Take the time to watch him walk away from you as you turn him back out to watch for any stiffness or unevenness.
Take the time to give him a day or two off for a grooming spa or some quiet handgrazing so his body and mind can rest each week.
Take the time to dip his bit in a bucket of water after your ride so there are no sharp-edged crusties next time you tack up (and you don't have to scrub later!).
Take the time to lay out your girth and saddle pad after riding so it can dry and stay mildew and fungus free.
Take the time to glance into his feed bucket -- is he cleaning it up? Sorting out the supplements he doesn't like?

Take the time to watch him eat hay or grass. Is he chewing easily and evenly or does he just mash it and let it fall out of his mouth?
Take the time after you pull his saddle off to curry the matted, sweaty hair, letting air reach the skin and re-fluffing his coat.
Take the time to inspect his manure and watch him pee. Is everything normal coloured? Is the flow and consistency of all his waste the same every day?
I am sure there are others; the take-home message is that these seemingly miniscule things can catch a problem early, saving you potential headaches, vet bills, and missed competitions. They also help make your horse's job more pleasant so he doesn't resent what you ask him to do. Keeping his body and mind fit is 100% vital to keeping him going year after year, not to mention it goes a long way to keeping your maintenance costs down. Fight the urge to rush, be a horse(wo)man, and train yourself to a routine that incorporates getting to know your horse's body and habits so that when something does change (oh yes, we know it will), you will be the first to know. The faster you notice, the faster you can fix it and get Dobbin back on track, which only gives you both more time to enjoy the good stuff!
