The short answer for a Hanoverian owner
Yes. A Hanoverian is usually kept for ridden work, often dressage or jumping, and that kind of athletic workload makes small changes matter. A little more hard feed during a heavier training block, a switch in hay supplier, or a shoeing cycle that quietly stretches a week longer can each show up later as lost condition, extra freshness, or uneven movement. Without notes, you are left guessing which change came first. A simple feeding and farrier log turns those guesses into a timeline you can actually work from.
What to write in the feeding side
Record the basics every day or at every change: the forage offered, the type and amount of any hard feed, supplements you use, turnout hours, and the workload that day, from rest to schooling to competition. Hanoverians are substantial warmbloods, and condition can creep up during a quiet month while the ration stays set for full work, so add a regular weight-tape reading and a note on how the girth is fitting and how the ribs feel under a flat hand. When something changes, write the date and the reason beside it. If your horse later looks leaner before a show or comes out sharper than usual, the log lets you compare appetite, droppings, and energy against the exact week the feed or routine shifted, instead of relying on memory from a busy yard.
What belongs in the farrier side
Note each visit date, whether your Hanoverian was shod all round, in front only, or trimmed, and anything the farrier observed: uneven wear, a loose shoe, a crack starting, or a change in hoof growth through wet ground. Between visits, jot down lost shoes and the foot involved, because a pattern on one side is useful information at the next appointment. Hanoverians are bred for expressive movement, so balance matters to how they step and land, and a record of how the feet looked across several cycles helps a new farrier understand what has been working rather than starting from a single snapshot on the day.
How the two halves help each other
Kept side by side, the two logs explain each other. A period of box rest changes both feeding needs and hoof growth. A step up to harder ground work can coincide with faster shoe wear. A ration change made for condition may line up with a farrier's comment about foot quality a cycle or two later. Writing both in one place, in date order, makes those links visible at a glance when you, your vet, or your farrier are trying to work out why something shifted.
When the log points you to professional help
A log does not diagnose anything, but it sharpens the moment you ask for help. Sudden feed refusal, repeated lost shoes on the same foot, a crack that deepens between visits, heat in a foot, or a Hanoverian who is suddenly reluctant to go forward all deserve a prompt call to your farrier or vet, and arriving with dates, feed changes, and workload notes helps them narrow things down faster.
Keeping it up without it becoming a chore
Tie entries to things you already do: update the feed lines when you make up feeds, add the farrier note before the lorry or car leaves the yard, and add the weight-tape figure on the same day each fortnight. Two honest lines written at the time beat a perfect page reconstructed later. Stored in KinsLe's Pet Passport, your Hanoverian's feeding history and shoeing record stay in a single packet you can hand over intact at a vet visit, a yard move, or a change of farrier.
