Fitness to travel is a decision, not a hope. Loading asks an animal to climb, balance, brace through corners and stand for the whole journey, and an animal that starts the day dull, lame or feverish will finish it worse. The checks below are deliberately plain: each one either passes on the day or postpones the trip, and they are done twice, the day before travel and again on the morning, so a developing problem is caught while plans can still change.
Brightness, Appetite and Normal Behaviour
Start by watching the animal undisturbed. A fit animal looks alert, notices you, moves willingly toward feed and behaves like itself. Confirm it has eaten its usual ration and drunk normally, because an animal off its feed before travel starts the journey on empty reserves and may be showing the first sign of illness. Check droppings too: diarrhoea, straining or no droppings at all are reasons to stop and investigate rather than load and hope. Compare everything with this animal's normal, since a quiet breed and a sick animal can look similar to a stranger yet very different to the person who feeds it daily.
Breathing, Temperature and Circulation
Watch breathing while the animal stands at rest, before handling raises its rate. Breathing should look easy and regular, without flared nostrils, coughing, discharge, a heaving flank or noise you do not usually hear. Take the temperature when you know how to do so safely for that species, and treat a raised temperature as a hard stop, because fever plus travel stress can worsen a mild problem during a single journey. Check that gums or other visible membranes look their normal colour and that the animal feels neither unusually hot nor cold to the touch. Any breathing struggle at rest ends the discussion: the animal needs a vet where it stands, not a trip.
Soundness, Legs, Feet and Skin
Walk the animal on firm, level ground and watch from the front, side and behind, then turn it both ways. It should bear weight evenly, track straight and turn without stumbling, dragging or protecting a limb. Run your hands down the legs for heat, swelling or pain, pick up and check feet where that is normal handling for the species, and look over the skin for open wounds, fresh swelling or sores that a partition, rug or halter would rub during travel. Lameness, a wound that could open or worsen, or a foot problem that makes balancing painful all mean the journey waits. Mild stiffness that the animal works out of in a few steps is information to share with the vet, not an automatic pass.
Judge Fitness Against the Journey Itself
Fitness is relative to distance, duration, weather and company. An animal that is borderline but stable might cope with a short, smooth trip to a nearby vet in cool conditions, yet the same animal should not face hours of standing, heat, loading stress at both ends and unfamiliar animals beside it. Young, elderly, heavily pregnant where travel is restricted, recently ill and recently injured animals all carry a thinner margin, so apply the checks more strictly to them. Build the honest option into your plan before the morning arrives: a contact who can be told the trip is off, and an alternative date, so postponing does not feel like failure.
When Doubt Means a Vet Assessment
If any check leaves you genuinely unsure, have a veterinarian assess the animal before travel rather than asking the journey to test it. Say exactly what you found, when you found it, and what journey you had planned, because the vet's answer is about this animal and this trip, not travel in general. Postpone immediately for fever, lameness, wounds or diarrhoea, and never mask a failing check by loading early, travelling slowly or hoping the animal brightens on the way. Record the outcome either way, so next time you judge from this animal's history rather than from memory.
Once both rounds of checks pass, store the dated results inside KinsLe within the Pet Passport section so the driver, handler and receiving vet all work from the identical fitness record.
