Build a Collie record that looks under the coat
A trend log for a Collie has to compensate for the breed's abundant coat, which makes visual weight checks unreliable for much of the year. Weigh weekly on the same scale at the same time and write the figure beside a rib-feel note taken with flat hands under the coat. Daily, record meals offered and eaten, walks and herding-style games, stool, and behaviour in steady words such as calm, watchful, pacing, or withdrawn. Collies are observant, routine-loving dogs, so note household changes, visitors, and schedule disruptions beside behaviour dips, because a sensitive Collie may eat less and watch more for a day after a change without anything being wrong.
Read appetite against routine and stomach comfort
Collies can have sensitive digestion, so the log should connect appetite to stool and routine rather than treating meals in isolation. Record what was fed, any new treat or table food, and the following day's stool quality, so a pattern of loose stool after a particular food is visible within a fortnight instead of being rediscovered monthly. Note whether appetite returned fully after a disrupted day or stayed soft across several days, and whether the dog still drank normally and enjoyed walks. A single quiet day after a thunderstorm is context; a week of soft appetite with changing stool is a trend, and the dated entries are what separate the two.
Track behaviour markers suited to a herding dog
Choose markers that fit a Collie's nature: interest in following family members around the house, enthusiasm for a familiar game, settling in the evening, and reaction to household movement. Rate each briefly every day, and add coat notes weekly, including shedding, dullness, or scratching, because coat change sometimes travels with appetite and weight change. A Collie who gradually shadows less, plays less, and leaves more food is showing a combined drift that no single day would reveal. Photographing the dog from above and from the side after grooming each month gives a visual record that supports the scale figures when the coat is at its fullest.
Add noise, visitors, and eye comfort to the Collie notes
Collies notice everything, so the behaviour column should record noise events, visitors, building work, and schedule changes beside appetite for those days. Note barking spells, hiding, or clinginess after such events, and whether eating returned to normal the next day. Also record eye comfort in plain words, such as squinting in bright sun or rubbing at an eye after a windy walk, with the date it appeared. A sensitive breed generates lots of one-day signals; the dated log is what proves most of them pass, and flags the few that quietly stay and grow.
Review monthly and bring the combined picture
At month end, lay the four weekly weights beside the appetite and behaviour summaries and look for lines moving together across two or more weeks. Contact a vet when that combined drift appears, or sooner for sharp changes such as repeated vomiting, refusal of food, marked tiredness, or obvious discomfort. Bring the log to the appointment, including the stool and routine notes, so the vet sees the timeline rather than a summary from memory. Kept in one place, KinsLe Pet Passport lets a Collie owner present a complete, dated picture of weight, appetite, coat, and behaviour without piecing it together the night before a visit.
