The growth curve flattens on a young Andalusian
The defining sign a young Andalusian horse is failing to thrive is growth that stalls while the foal's peers keep growing. Andalusian foals typically fill out steadily through their first months, developing the rounded hindquarters and substance the breed is known for. A foal whose ribs begin to show, whose hip bones sharpen, or whose topline dips instead of levelling is moving the wrong way. Comparing the foal to others of a similar age in the same herd sharpens the judgement, and so does a weight tape used the same way each week — a flat or falling line over a fortnight is a finding, not an impression.
Energy and appetite drain away
A young Andalusian failing to thrive usually fades behaviourally before it looks truly ill. The healthy foal gallops in bursts, pesters its dam, investigates everything, and nurses with determination. The struggling foal stands apart with its head low, lies down for long stretches while others play, and nurses briefly and without force before drifting off. At the feed bucket or creep, it mouths feed rather than eating with appetite. A dull, staring coat that fails to shed like its stablemates' coats, and a tucked-up belly on a foal that should be round, complete a picture any experienced eye reads as a foal not doing.
Gut signs and recurring small problems
Repeated loose droppings in a young Andalusian foal suggest the gut is not converting feed into growth, and a foal that swings between scouring and normality over weeks is not having a run of bad luck — it is showing a pattern. Snotty noses that never quite clear, minor coughs that keep returning, and small setbacks that each take longer to bounce back from also belong in the picture: a foal failing to thrive often cannot shake the ordinary challenges its herd mates shrug off. Check the mare as well as the foal, because a dam whose milk has dropped off produces exactly this foal from the supply side.
When a young Andalusian needs veterinary investigation
Arrange a vet visit when a young Andalusian foal's weight stalls or falls across two weekly checks, when scouring persists beyond a couple of days, or when appetite and energy stay flat for more than a few days. Seek help the same day for a foal that is weak, reluctant to rise, nursing poorly, or visibly dehydrated. Failure to thrive is a description, not an explanation — the vet's job is to find what sits underneath, and your records of weights, feeds, droppings, and the mare's condition give that investigation its starting evidence rather than a blank page.
One growth record from birth onward
A foal's early months generate scattered facts: birth notes in one notebook, a weight scribbled on a feed sack, a vet's remark remembered by whoever was holding the foal. Failure to thrive is diagnosed from the joins between those facts, so the record needs to live in one place and travel with the foal between yard, vet, and any future owner. A KinsLe Pet Passport gathers the young Andalusian's weights, health notes, and visit records into a single portable packet, so the foal's growth story is complete and readable wherever it is next examined.
