"Every six weeks" is the number everyone repeats and it is not what the published sources say. UF/IFAS Extension schedules most horses at five to eight weeks and notes that wet conditions may need more frequent visits. University of Minnesota Extension's guidance, as indexed, is at least every six to eight weeks in summer and six to twelve in winter because hooves grow more slowly then, and says explicitly that the interval differs between horses. A 2017 study of 26 riding school horses measured what changes inside a four to six week cycle and found the changes were real. Nobody publishes a single correct number, and the spread between the published ones is wider than most owners realise.
The four published positions, side by side
| Source | What it says |
|---|---|
| UF/IFAS Extension | "Schedule regular farrier visits. For most horses, this will mean a visit every 5-8 weeks." Frequency depends on individual needs, and "wet conditions may necessitate more frequent visits" |
| University of Minnesota Extension | Trim or shoe at least every 6 to 8 weeks in summer; every 6 to 12 weeks in winter, because hooves grow more slowly then. States the interval may differ between horses based on hoof growth |
| Leśniak et al. 2017 | Measured 26 riding school horses before and after farriery on a four to six week interval and concluded the results "support regular (four to six week) farriery intervals for the optimal prevention of excess loading of palmar limb structures" |
| The consensus you will hear at the barn | Six weeks, flat, all year, all horses |

Look at the spread. The published range across those three runs from four weeks at the short end to twelve at the long, and the reasons given for the variation are hoof growth rate, season, individual horse and ground conditions. "Six weeks" sits in the middle of that range and is repeated as though it were the whole of it.
What the study actually found, and what it does not say
This is the only measured evidence on the page and it deserves to be read precisely rather than waved at.
Leśniak, Williams, Kuznik and Douglas published in Animals 7(4): 29 in 2017. The design was an observational study of 26 mixed-breed riding school horses, using digital photographic analysis of hoof measurements taken before and after farriery on a four to six week interval.
What they found: "a four to six week interval retains consistency within fetlock joint angles and vertical displacement of the HPA, positively influencing dorsopalmar balance." They also found that measurable change occurred even within that short interval, including an average palmar shift in the center of pressure of 0.5 cm and changes in hoof wall angles, which meant they rejected their own starting hypothesis that no significant changes would occur.
Their conclusion: "the results support regular (four to six week) farriery intervals for the optimal prevention of excess loading of palmar limb structures, reducing long-term injury risks through cumulative, excessive loading."
What that is: evidence that measurable change happens inside a short cycle in a specific population of working riding school horses.
What it is not: a rule for your horse. Twenty-six horses of one type, in one setting, is not a national schedule, and the authors did not present it as one.
The variable that decides your horse's number
Growth rate, and it is not the same for every horse.
UF/IFAS gives the average: "for a mature horse, the average hoof growth per month is three-eighths inch." Minnesota's guidance, as indexed, adds that a hoof takes roughly nine to twelve months to grow out entirely and that hooves grow more slowly in winter, which is why its winter window stretches to twelve weeks.
Two consequences follow.
Your neighbor's eight-week horse is not a rebuke. If his horse grows foot more slowly than yours, an eight-week cycle on that horse and a five-week cycle on yours can both be right.
Your own horse's number changes with the season. The same horse can genuinely need the farrier more often in summer than in winter. A fixed date in the diary all year is a convenience, not a schedule.
The things that shorten the interval
- Wet ground. UF/IFAS says directly that wet conditions may need more frequent visits, and separately that overexposure to wet conditions can lead to hoof infections and weakened hooves. This is the same argument as the one in wet paddock management.
- Work on hard or abrasive surfaces, which changes how the foot wears between visits.
- Fast growth, which is individual.
- Shoes rather than barefoot, because a shod foot does not self-wear in the same way and the shoe stays where it was nailed while the foot grows past it.
- Any existing foot problem, in which case the interval is your farrier's and your vet's call rather than a schedule.
How to tell your horse is due, without a calendar
The calendar is a planning tool. The foot is the evidence. What to look at while you are picking out feet, which we set out in picking out feet:
- Risen clenches. The nail ends standing proud of the wall. A reliable and early sign on a shod horse, and a hazard in itself because they cut the opposite leg.
- The shoe no longer covering the foot. The wall has grown out past the edge of the shoe.
- A shoe that moves when you try it with your fingers.
- Flares and chips at the bottom edge on a barefoot horse.
- A change in how he moves on hard ground, or a stumble that is new.
None of these is a reason to do anything yourself. They are a reason to call the farrier, and that is the only action this page attaches to them.
The one thing worth not economising on
The temptation to stretch a cycle is almost always financial and it is usually strongest in winter, which is also when UF/IFAS notes that wet conditions may need more visits rather than fewer, and when Merck's list of conditions associated with thrush includes irregular farrier care (Merck Veterinary Manual, Thrush in Horses, read 2026-08-28).
If the cost of the cycle is the problem, that is a real problem and a conversation to have openly with your farrier about what is possible, rather than a decision to make silently by not booking. It also belongs in the budget you built before the horse arrived, which is the argument in the hidden costs of horse ownership.
FAQ
How often does a horse need to be shod or trimmed?
There is no single published number. UF/IFAS Extension puts most horses at every five to eight weeks. University of Minnesota Extension's guidance is at least every six to eight weeks in summer and six to twelve in winter, and says the interval differs between horses. A 2017 study of 26 riding school horses supported a four to six week interval for that population.
Why does everyone say six weeks?
Because it sits in the middle of the published range and it is easy to diary. The sources that publish a range give reasons for the variation, growth rate, season, individual horse and ground conditions, and six weeks discards all four.
Can my horse go eight weeks between farrier visits?
Some horses can, on the published ranges, especially in winter. Whether yours is one of them is a question for your farrier, who can see the foot at the end of a cycle. Growth rate is individual and UF/IFAS puts the average at three-eighths of an inch a month.
Do hooves grow more slowly in winter?
That is the reason Minnesota Extension's winter window stretches to twelve weeks while its summer guidance is six to eight. It is also why a fixed all-year interval fits some horses badly at one end of the year.
How do I know my horse is due before the appointment?
Risen clenches, the wall grown out past the edge of the shoe, a shoe that moves under your fingers, flares or chips on a barefoot horse, or a change in how he moves on hard ground. All of them are reasons to call the farrier, not to do anything yourself.
Is it worse to be early or late?
Nobody publishes an answer to that, so no answer is given here. What is published is that wet conditions may need more frequent visits, that irregular farrier care is among the conditions associated with thrush, and that measurable change occurs even within a four to six week cycle.

A note on one source. University of Minnesota Extension's "Caring for your horse's hooves" page returned HTTP 403 to our request on 2026-08-28, so we could not open it and read it directly. Its six to eight week summer and six to twelve week winter guidance, and the nine to twelve month grow-out figure, are reported here from the indexed summary of that page rather than from a page we opened, and are labelled as such rather than presented as a verbatim read. That is our retrieval failing, not anything on Minnesota's side, and a writer with working access should replace this paragraph with a direct read.
This site is not written by a veterinarian or a farrier. Nothing here is a diagnosis or a trimming instruction, and no figure on this page is ours.
