What appetite and weight changes are common in an aging Morgan horse?

Published October 29, 2026

The short answer

In a senior Morgan, weight often changes where fat sits rather than how much he eats, with a firmer crest, fuller tailhead and padding around the sheath appearing while appetite stays steady. A real drop in interest in hay or bucket feed therefore deserves attention in this breed, because it more often points to teeth, pain or another health shift than to simple ageing. Many Morgans work lightly well into their late twenties, so preserving topline muscle matters alongside watching those regional deposits. KinsLe Pet Passport lets you log crest checks, weight-tape readings and dental notes for your Morgan in one record you can show at each vet visit.

Where a Senior Morgan Puts Weight First

A senior Morgan rarely gains or loses evenly across his whole frame. The places to read first are regional: the crest along the top of his neck, the tailhead, the area behind his shoulder and, in geldings, around the sheath. A crest that feels firmer and thicker under your palm, or tailhead padding that softens the bones you used to feel easily, can develop while the weight tape barely moves and his ribs still feel about right. That is why hands matter more than a single number in this breed. Run them over the same landmarks in the same order each time, and note what you feel, because a Morgan can look reassuringly round in a photograph while the fat is concentrating exactly where metabolic concerns tend to show first.

When a Steady Appetite Changes, Look Elsewhere

Appetite in an older Morgan is usually steady, and that steadiness is useful information. A horse who has cleaned up for years and suddenly leaves half his hay, drops wads of partly chewed forage, or finishes his bucket but walks away from the hay net is telling you something changed, and simple ageing is not the first explanation to settle for. Worn or uneven teeth make long-stem hay slow work long before they affect softer feed. Discomfort elsewhere in the body can do the same, as can a ration that no longer suits him. Treat a new pickiness in a Morgan as a prompt to check his mouth, watch him chew, and review what else has shifted, rather than as a reason to simply offer richer feed he might not need.

Holding Muscle on a Morgan Still in Light Work

Muscle, not fat, is what keeps a working senior Morgan looking and moving well. Many Morgans are still ridden or driven regularly in their mid to late twenties, and that continued movement is part of how they keep a topline. When work quietly shrinks to occasional weekends, the back and hindquarters lose tone even if the crest stays full, producing a horse who is simultaneously over-fat in patches and under-muscled where it counts. Regular gentle exercise suited to his soundness, turnout where he keeps moving around the field, and forage-based feeding reviewed as his workload changes all help protect that muscle. If his topline is fading despite steady work and feed, that mismatch itself is worth raising with your vet rather than answering with ever larger meals.

A Vet-Visit Rhythm Built Around the Trend

The most useful thing an owner of a senior Morgan can bring to an appointment is a trend, not an impression. Bring your tape readings, your crest and tailhead notes, and a short record of any appetite change, including whether hay or bucket feed was refused first. At a routine visit you can ask your vet whether bloodwork makes sense for your Morgan's overall picture, given his shape and history, and let the vet judge what, if anything, to test. Call sooner rather than waiting for a routine visit if he goes off feed completely, chokes, loses weight quickly, develops obvious foot tenderness, or shifts his weight repeatedly from foot to foot. Keeping that Morgan-specific picture together is easier in KinsLe Pet Passport, where crest notes, work level and tape readings sit with his dental history as one story his vet can follow.
