Colic signs that mean call now, not in the morning
Colic is the emergency vets are called to most, and the dividing line is persistence. A horse that paws, looks at his flank, rolls, gets up and down, sweats without work, or passes little or no manure deserves a call the moment the behaviour repeats or escalates rather than easing within a short spell of walking and quiet. Rolling that becomes violent, a horse that throws himself down, a racing pulse you can feel in the jaw, and gums that look dark, dry or tacky all push the situation from urgent to critical. Mild signs that settle completely can be reported to your vet for advice, but colic that keeps returning in waves is never a wait-until-morning problem, because gut conditions can deteriorate quietly and fast.
Choke, breathing trouble and heavy bleeding
A horse with choke cannot swallow properly: feed material and saliva pour from the nostrils, the horse coughs, stretches his neck and looks distressed, even though he can still breathe. That is an emergency call, and the horse should have all feed and water removed while you wait. Breathing emergencies include a horse working hard to breathe at rest, flared nostrils with noisy airflow, or swelling around the head and throat after a sting or reaction. Heavy bleeding that soaks through a pad, spurts, or will not slow with firm pressure needs a vet immediately, as does any wound over a joint, tendon or eye, where what is underneath matters far more than how the surface looks.
Legs, eyes and the horse that is down
A horse that will not bear weight on one leg, has a limb at an odd angle, or has swollen heat-filled joints after a knock should be kept standing exactly where he is until the vet arrives, because moving a suspected fracture makes it worse. Eye problems are emergencies on a shorter fuse than most owners expect: a closed, weeping, cloudy eye or one with a visible injury can deteriorate within hours, and horses hide eye pain by simply shutting the eye. A horse that is down and cannot rise, or rises and falls repeatedly, is always an emergency, whether the cause turns out to be colic, weakness, injury or something neurological. Profuse sweating, trembling and distress out of proportion to the weather belong on the same call-now list.
Foaling emergencies
A mare who strains hard for twenty minutes without producing a foal, produces a red membrane first instead of a white one, or delivers a foal that is weak, limp or not breathing steadily needs help immediately, and foaling is the one emergency where minutes genuinely change the outcome for two lives. A mare that retains the afterbirth for several hours, or becomes dull, hot and off her feed in the days after foaling, also needs a vet the same day rather than monitoring at home.
What to do while the vet travels
Phone first, then act: keep the horse calm and contained, remove feed from a colicking or choking horse, and walk a mildly colicky horse only if your vet advises it during the call. Write down when signs started, when they changed, what the horse last ate, when he last passed manure, and anything he could have got into, because the timeline shapes the vet's first decisions. Have the horse caught, lit and accessible before the vet arrives, with his documents to hand. Keeping that history current in KinsLe's Pet Passport means the packet the vet works from is already assembled, even when the emergency happens in the middle of the night.
