The Andalusian, formally the Pure Spanish Horse, was shaped by centuries of work on sparse Iberian grazing, and its constitution reflects that: thrifty, tough, and inclined to live long. Most of the breed's health watch list follows from that thriftiness meeting modern lush pasture, plus one well-known quirk of its commonest colour. None of it is cause for alarm, but all of it rewards an owner who checks deliberately rather than assuming a hardy breed needs no watching.
The easy keeper's bargain: weight and metabolism
Andalusians extract a great deal from very little feed, and on generous grazing they gain weight fast, laying down a hard, cresty neck and fat pads behind the shoulders and over the tail head. That pattern is the visible edge of metabolic strain, which raises the risk of laminitis, the painful hoof condition every owner of a native-type breed learns to respect. Weigh-tape your horse regularly, score the crest honestly, and watch for the early laminitis clues: reluctance to turn, a pottery gait on hard ground, and warmth or a bounding pulse in the feet.
Melanoma checks for the grey majority
A large share of Andalusians are grey, and grey horses as a group are prone to melanomas, slow-growing lumps that favour the skin under the tail, around the anus and genitals, at the corners of the mouth, and around the ears and eyelids. Run your hands over those areas at grooming time and learn what is normal for your horse, because the value lies in noticing a new lump or one that changes. Most remain quiet for years, but any lump that grows quickly, ulcerates, or interferes with tack, droppings, or the tail itself earns a vet examination rather than continued watching.
Teeth, eyes, and everyday soundness
The breed's strong, dense bone and generally good feet are assets, but no breed is exempt from the ordinary: dental wear that makes chewing inefficient in the teens and beyond, eye problems such as cataracts or recurring inflammation, and the joint stiffness of a long working life. Watch for quidding, where partly chewed hay drops from the mouth, for weight loss in an old horse whose ration has not changed, and for any cloudiness or soreness in an eye, which always deserves prompt attention rather than home observation.
The older Andalusian and pituitary change
Because Andalusians commonly work and live well into their twenties, pituitary pars intermedia dysfunction, the hormone disorder of older horses, belongs on the watch list. Its signs include a coat that grows long and curly and fails to shed, increased drinking and urination, loss of topline muscle, and a new vulnerability to laminitis. An annual blood test discussion with your vet in the senior years catches the change while management can still get ahead of it.
Watching with a record, not a memory
For a breed whose problems creep, trends matter more than single observations: this season's weight against last season's, the lump that was pea-sized in spring, the crest that firmed up over a month. Keeping those measurements, lump maps, and vet findings in KinsLe's Pet Passport means you arrive at each check with evidence instead of impressions, which is exactly what a thrifty, long-lived horse needs from its owner.
