A draft horse's appetite is a big number to lose
A Clydesdale in steady work or growth eats on a scale that dwarfs a riding horse's ration, so appetite changes in this breed carry outsized weight. The changes that should prompt a vet visit include leaving hay in the net he normally empties, walking away from a feed he usually finishes to the last scrape, and drinking noticeably less in parallel. Slower eating matters too: a giant who once demolished his hay in a steady rhythm but now picks, rests his head, and returns half-heartedly may be dealing with mouth pain, discomfort, or the early stages of feeling generally unwell, and that pattern deserves reporting before it becomes outright refusal.
Dropped feed and slow chewing point to the mouth
Watch how a Clydesdale actually processes a meal. Dropping wads of partly chewed hay, packing feed into one cheek, tilting the head while chewing, or letting hard feed fall from the lips are mechanical eating problems, and in a horse whose teeth work through enormous volumes of forage, dental wear or a sore mouth shows up first as appetite change rather than as visible weight loss. Tell the vet what the dropped feed looks like and which feeds he manages best, because a horse who still eats soft feed keenly but refuses long hay is telling a different story from one who refuses everything.
When appetite loss arrives with gut signs, move faster
Appetite gone plus a quiet stable is the combination that should shorten your timeline sharply. A Clydesdale who stops eating and also stops passing droppings, who paws the bedding, lies down and rises repeatedly, sweats at rest, or stands stretched and tucked up needs a vet the same day, urgently if the restlessness builds. Drooling with repeated swallowing or neck stretching after a mouthful raises the possibility of an obstruction in the throat or gullet, which is an emergency call in any horse and no less so in a gentle giant; do not offer more feed while you wait for advice. Breathing changes, dullness, or weakness alongside refusal move the call from prompt to immediate.
The slow slide that draft owners can miss
Not every case arrives dramatically. A Clydesdale's sheer mass can conceal a gradual shortfall for weeks: the hay bill dips slightly, the girth goes up a hole, the barrel loses its filled look after feeding, and condition slips along the neck and quarters where muscle should round the frame. Because these horses are often kept for showing, driving, or breeding on carefully planned rations, keep the ration written down and weigh-tape him on a schedule, so a slow appetite fade shows up as numbers rather than as a surprise at the next show.
Information that helps the vet triage a very large patient
When you phone, quantify in this horse's own units: how many nets or slices he usually eats and what fraction is left, how long a feed normally lasts him, whether droppings have changed in number or dryness, and whether he is drinking his usual amount from a source you can actually measure. Have him in a well-lit box with room around him before the vet arrives; examining the mouth and gut of a horse this size goes better with space, light, and a handler he trusts already in place.
Why his feeding baseline belongs in writing
Few people can hold a Clydesdale's full normal ration in memory accurately enough to spot a fifteen percent fade, and yards, shows, and covering staff multiply the number of hands feeding him. A written baseline — forage amounts, feed times, eating speed, droppings pattern, dental dates — turns 'he seems off his hay' into a measurable change anyone can verify. Recording that baseline in his KinsLe Pet Passport with his veterinary history means the next person feeding this enormous horse, and the vet advising on him, start from his real normal rather than from a guess about what a big horse probably eats.
