How do I write down a bearded dragon's brumation dates each winter so year-to-year changes are easy to compare?

Published October 26, 2026

The short answer

Give each winter its own block in the record: when your dragon's appetite faded, when daytime sleeping began in earnest, the date he went down fully, any brief weigh-ins while he slept, and the date he woke and took his first meal. Add how much weight changed across the sleep, and the block is complete. Laid one under another, those winter blocks make year-to-year comparison a glance instead of a guess. KinsLe's Pet Passport keeps each winter's brumation block in your dragon's records packet, in order, where next winter's notes can join them.

One Block Per Winter, Written the Same Way

Brumation records fail the same way most records fail: each winter gets noted in a different style, in a different place, until comparison becomes archaeology. The cure is a fixed block — the same handful of lines, in the same order, every winter. Appetite fading, daytime sleeping taking over, the date he went down fully, brief checks while he slept, the date he woke, and how eating resumed. Written identically each year, the blocks stack into something genuinely useful: a row of winters you can scan in a minute. Keep the block in the same record as his everyday notes but visibly separate — a clear heading per winter — so the season reads as one chapter rather than scattered entries.

The Dates That Frame a Brumation

Four dates do most of the work. First, the last proper meal — the feed he ate with his usual enthusiasm before appetite tapered — because digestion should be long finished before deep sleep. Second, the point where daytime sleeping clearly took over from ordinary basking and exploring. Third, the wake: the morning he was out, alert and looking for food as if a switch had been thrown, which it often resembles. Fourth, the first real meal after waking, which sometimes lags the wake itself by days. Around those four, add the small facts: how far basking lights and temperatures were reduced, if they were, and any mid-sleep drinks or soaks he accepted. That skeleton, repeated yearly, is the comparison engine.

Weigh-Ins During the Sleep: Brief and Rare

Weigh him going in — at the last-meal stage — and coming out, in the first days after waking, and those two numbers frame the winter's cost. A mid-sleep weigh is worth it only if something concerns you; hauling a brumating dragon out weekly to satisfy a spreadsheet disturbs the very rest you are recording, and a healthy brumation should show only a small change in weight across the whole sleep. Write the two numbers into the block beside the dates, because a winter that lasted ten weeks at almost no weight change and a winter that lasted ten weeks with a noticeable loss are different winters, and only the record can tell them apart next year.

Comparing Winters Is the Whole Point

With two or three blocks stacked, patterns stand up. His sleeps may lengthen as he matures, or settle into a dependable length; the wake-up appetite may be instant one year and slow the next after a colder winter. A dragon whose brumation starts noticeably earlier each year, or whose post-winter weight trend steps down winter after winter, is showing you a trajectory while it is still cheap to investigate. This is also where husbandry changes prove themselves: if you adjusted his light cycle or winter temperatures, the block that follows is the verdict, written in his dates rather than your impressions.

The Winter Notes That Mean a Vet, Not Patience

Most brumation oddities are just brumation, but the block should record the exceptions in the same plain style, because they are the entries that matter most. A black beard that appears during sleep and does not lift, discharge around the eyes or mouth, a marked loss of weight across the winter, or a dragon who wakes and then refuses food well beyond his usual few days — note it, and let a vet see the record rather than your summary of it. In KinsLe, each winter's brumation block sits in your dragon's Pet Passport in order, so the story of his winters builds in one packet and next winter's block can be laid beside the last at a glance.
