Autumn laminitis in horses is consistently underestimated, because the condition has been so firmly associated with spring in the minds of most owners that the second seasonal peak arrives unannounced. September and October bring warm days, cold nights and a flush of new growth that behaves in the pasture much as May does, and the yards that tightened grazing management in spring have very often relaxed it again by then. Providers of horse cremations across Lancashire, Merseyside and Cheshire see the consequences of severe autumn cases every year, and they arrive with a grim predictability once the first frosts appear.
Why Autumn Grass Behaves Differently From Summer Grass
Grass produces sugars during daylight and uses them to grow overnight. When night temperatures fall below roughly five degrees, growth slows dramatically while photosynthesis continues through the day, so the sugars accumulate in the leaf instead of being spent. A frosty September night followed by a bright, still morning produces pasture with a sugar content far higher than anything the same field carried in August. Horses grazing at eight in the morning on that grass are eating something quite different from what they ate the previous week, and nothing about the field looks any different to the person leaning on the gate.
The autumn flush compounds this. After the dry, hard grazing of late summer, the first proper rains bring rapid regrowth, and that young leaf is both palatable and rich. Horses that have been grazing sparse ground for weeks are suddenly presented with abundance, and they respond accordingly. Add in a natural seasonal rise in the hormone ACTH that occurs in every horse through late summer and autumn, and the metabolic picture becomes considerably less forgiving than it was in July.
The Autumn ACTH Rise and Older Horses
Every horse experiences an increase in ACTH between roughly August and October, part of a normal seasonal cycle. In a horse with pituitary pars intermedia dysfunction, more commonly known as Cushing’s disease, that rise is exaggerated and can be enough on its own to tip an animal into laminitis. This is why so many first laminitic episodes in older horses occur in autumn rather than spring, and why a veteran that has never had a problem in fifteen summers can founder badly at nineteen. Owners frequently describe it as coming from nowhere, which from their point of view it did.
Testing ACTH in autumn is genuinely useful, provided the results are interpreted against seasonally adjusted reference ranges rather than the figures used in winter. A horse that tests normal in February may test clearly abnormal in September, and that information changes management decisions for the year ahead. Where medication is already in place, autumn is often the point at which a dose needs reviewing. The wider guidance on early laminitis warning signs applies equally to the autumn peak, and the subtle changes it describes are worth rereading as the nights draw in.
Recognising Autumn Laminitis Before It Becomes Severe
The classic rocked back stance and reluctance to walk represent an advanced case rather than an early one. What comes first is usually far quieter. A horse takes shorter strides on a hard surface, turns stiffly in the stable, shifts weight from one front foot to the other while standing, or simply stands more than it grazes. Digital pulses become stronger and easier to find. A horse that has always led out briskly hangs back at the gate. These signs are easy to attribute to a cold morning or stiffness in an older animal, and that misattribution does real damage to feet.
Restricting grazing in autumn requires the same discipline applied in spring, which means avoiding the sugar peak of late morning and early afternoon, using strip grazing or a track, and putting muzzles back on animals that wore them in May. Soaked hay and a properly balanced low sugar diet matter more than any supplement. Yards around Preston and the market town grazing near Nantwich, where good pasture is plentiful and horses do well on very little, see repeated autumn cases for exactly that reason, and owners in those areas often first encounter the pages covering Preston horse cremations or Nantwich horse cremations at the end of a difficult autumn.
When Laminitis Reaches a Point of No Return
Most laminitic episodes are survivable, and many horses go on to years of comfortable life with careful management. A proportion, however, involve rotation or sinking of the pedal bone severe enough that pain cannot be controlled, and in those cases the conversation with the vet turns towards ending suffering rather than treating it. That conversation is rarely sudden. It usually follows weeks of box rest, radiographs, remedial farriery and a slow erosion of hope, which makes it one of the hardest end of life decisions a horse owner faces.
Because it is anticipated rather than sudden, there is usually time to plan, and that time is worth using. A planned euthanasia allows an owner to choose the day, the place on the yard, who is present and what happens afterwards, rather than making every decision in a crisis. Many owners arrange for the horse to be in a familiar spot, with a companion nearby and a favourite feed to hand. Knowing in advance that individual cremation with ashes returned has been arranged removes one enormous decision from a day that already contains too many.
Carrying the Decision Afterwards
Owners who have lost a horse to laminitis carry a particular weight, because the condition is so closely tied to management that guilt attaches to it in a way it does not with colic or injury. The thinking runs in circles. The muzzle that came off in August, the field that was not strip grazed, the vet appointment postponed by a fortnight. Very little of that reasoning survives contact with the facts, since autumn laminitis has causes well beyond any owner’s control, but the reasoning happens anyway and it helps nobody to be told it should not.
What tends to help more is talking to people who have made the same decision, and to a team who deal with these losses regularly and understand the shape of them. Owners around Formby and the coastal grazing of south west Lancashire will find the details on Formby horse cremations a useful reference, and anyone wanting to talk through arrangements before or after a loss can reach the team through the contact us page or by calling 01704 776976 at any time of day or night.
