The most common mistake after a new pet arrives is "a lot of information, but little that can be used": plenty of photos and subjective notes, but no unified timeline or comparable data. The real goal of week one is not to fill a diary; it is to establish three baselines: weight/body condition, eating and elimination, and energy/activity rhythm. Once these three lines are stable, you can judge much faster whether later changes come from stress, diet, or possible illness.
On day 1, complete the minimum profile fields first: species, life stage, prior vaccination/deworming history (if known), allergy history, and source. Record three short checks that day - morning, midday, and evening - with appetite, energy, and stool form/frequency. Keep records concise and timestamps consistent. On days 2-7, keep the same observation windows so trends can be compared.
Week one does not require a "perfect diet," but it does require records you can explain. If a diet change is necessary, mark the start date and comparison plan separately; do not stack it with other variables in the same period. If soft stool or appetite fluctuation appears, record context such as travel/carrier stress, noise, boarding, and other factors, or later review will lose reliability.
Do not schedule vaccination or deworming on your own in week one; follow your veterinarian's plan. You can still record planned timing, veterinary advice, and known history gaps in the profile and complete details at the visit. If prior records exist, organize them into a timeline: vaccine name, dose number, date, and reactions. Clearer gaps make catch-up much easier.
End week one with a short recap: which baselines are established, what is confirmed, what is still open, and next week's focus. A recap moves attention from scattered notes back to action - for example, "weigh every Tuesday" or "track stool shape for three more days." This is more useful than many one-off entries.
Key takeaways
- Build baselines first: weight/body condition, eating and elimination, energy and activity rhythm.
- Fixed observation windows: short entries at the same times daily; comparability first.
- Label diet changes separately: avoid stacking with stress, deworming, and other variables in the same window.
- Weekly recap: three baselines + one executable action for next week.
