A donkey changes shape slowly, and that slowness is the trap. Weight creeps on across a summer of good grass, or slips away across a winter, a little at a time, while the thick coat and the familiar silhouette tell you nothing has changed. A monthly record breaks that illusion, but only if each month is measured the same way, written the same way, and read against the months around it. One reading is a snapshot; twelve readings in a row are a trend, and the trend is what should drive feeding decisions.
Measuring the Same Way Every Month
Pick a fixed day each month and keep the conditions steady: the same time of day, before the morning feed, on level ground, with the donkey standing square. Take the weight by weigh tape, fitted in the same position each time, or on a scale if one is available, and write the figure down before you do anything else. Then score condition twice over — by eye first, looking along the neck, ribs, and hindquarters, and then by hand, because a donkey stores fat in distinct patches rather than in an even layer. Feel the crest of the neck, the ribs, and the hindquarters individually, and note each area separately rather than collapsing them into one impression; a firm, thickened crest can be growing while the ribs still feel reasonable. Use one scoring approach, the one your vet uses, and stay with it all year. A photograph from the same side, the same distance, and the same light each month makes an honest backup to the figures.
What Each Entry Notes Beside the Figures
Figures without context cannot be interpreted later, so each monthly entry also records what the donkey has been living on and doing. Note the grazing hours and how the pasture looked, the hay offered, any hard feed and its amount, and the work or exercise the donkey did. Add appetite, any sign that chewing has become slow or messy, and coat changes. When a figure moves, this context is what tells you why: a weight rise alongside longer grazing and no work is a feeding problem to correct in small steps, while weight loss alongside poor chewing points toward teeth and a vet visit. Write the entry on the day of measuring, while the month just lived is still clear in your mind.
Expect the tape and your hands to disagree now and then, and record both when they do. A tape measures girth at one point; a crested neck or a growing pot belly can develop while girth barely moves, which is exactly why the hand scores for the crest, ribs, and hindquarters are written as separate notes rather than averaged into the tape figure. Seasonal coat changes muddy the eye score most, in the months when the coat is thickest, so in those months the hand scores carry the entry and the photograph matters least.
Reading Months Against Each Other
Lay the entries out in order and read down the columns. A single month's rise after a flush of grass is weather; the same small rise three months running is a direction, and it calls for a gradual cut in grazing time or hard feed rather than a sudden restriction. The same applies in reverse: slow loss across several entries, especially with a thickening crest staying put while ribs sharpen, deserves a prompt conversation with your vet rather than another month of watching. The trend lives in the donkey's Pet Passport, where each month's figures and notes sit together in order and can be shown to the vet as one continuous story. Read month against month, the Pet Passport chart on KinsLe shows whether forage changes are holding a donkey steady or quietly pushing weight upward.
