The healthy Harlequin is bright in both senses
A healthy Harlequin rabbit is an engaged, medium-sized rabbit who investigates his space, comes forward at feeding time, and spends long periods working through hay. His eyes should be bright and free of discharge, his nose dry, and his breathing silent when he is at rest. The famous markings, alternating bands and patches of colour divided along the body and split down the face, should look crisp because the coat carrying them is in good condition: dense, glossy, and lying flat. Dullness in a Harlequin tends to arrive as a package, coat losing its sheen at the same time as appetite and energy dip, so treat that combination as an early prompt to look closer rather than three separate coincidences.
Coat and skin checks across the colour bands
Run your hands against and with the fur across both colour zones. Healthy skin underneath is smooth and unbroken, without the flaky scaling along the spine that can signal mites, and without bald patches, mats, or scratching sores behind the ears and at the hips. Ears themselves should be clean and dry inside, with no dark crusting, and the fur under the chin should be dry to the touch. Check the hocks by parting the fur on the rear feet: a healthy Harlequin who lives on suitable flooring keeps those points furred and intact. His rear end should be clean and dry too, because a rabbit grooming properly and eating his soft night droppings directly leaves almost no evidence behind.
Eating, droppings, and teeth working together
The mechanics of health in any rabbit show up in the hay rack and the litter tray. A healthy Harlequin eats hay as his main occupation, chews with a wide side-to-side grind, and produces a generous volume of round, dry droppings of consistent size. Lift his lip weekly to see front teeth that meet evenly, without slant, chips, or one tooth racing ahead of the other. Warning patterns are specific: hay picked up and dropped, a preference for soft foods only, droppings shrinking across a few days, or damp fur appearing under the chin. Each of those moves the mouth to the top of the suspect list, and none of them resolves by waiting, because the underlying wear problem compounds daily.
Weight and movement on a medium frame
Handle and weigh your Harlequin weekly. He should feel balanced and muscular, ribs covered by a smooth layer, spine not sharp, belly comfortable. A scale reading that holds steady across the month is one of the most dependable health signs this breed offers, and a trend in either direction, found early, is far easier to address than a dramatic change found late. Watch him move: a healthy Harlequin hops symmetrically, turns freely, sits up to wash his face with both paws, including along that divided face pattern, and settles into relaxed stretches. Reluctance to move, a lop-sided gait, or sitting hunched in one spot all contrast sharply with his normal and deserve attention.
Acting on the drift away from healthy
Contact your vet promptly if your Harlequin stops eating hay, droppings shrink or stop, breathing becomes audible, the chin wets with drool, hock sores open, or he sits hunched with quiet tooth grinding, and treat a rabbit who has stopped eating altogether as a same-day case. Arrive able to say when the coat dulled, how the weight has moved, and which foods he still accepts. Keeping that dated picture in KinsLe's Pet Passport gives your Harlequin's vet a record as distinctly organised as the rabbit himself.
