Measure growth on a rhythm you can keep
Puppies grow in spurts that fool the eye, so a simple measurement routine beats occasional guesses. Weigh your puppy weekly during the rapid early months, using the same scales and roughly the same time of day, then shift to monthly as growth steadies. A practical home method is weighing yourself holding her, then without her, and subtracting. Record height at the shoulder monthly with a tape against a wall, and take one standing photo in the same doorway each time, because that photo series shows shape change that numbers alone miss, legs lengthening, chest deepening, and the gangly stage arriving.
Log the milestones that actually matter
A milestone list should capture firsts you will want to remember and firsts your trainer or vet will ask about. Note the date your puppy first slept through the night, first settled alone, first recalled away from a distraction outdoors, first walked calmly past another dog, and first travelled happily in the car. Add socialisation experiences as they happen, the surfaces, sounds, people, and places she has met calmly, because gaps in that list explain later wobbles better than memory does. Keep entries honest: record the date a behaviour was reliable, not the first fluke success.
Put health, food, and growth on one timeline
Growth data becomes far more useful when it sits beside the rest of puppy life. On the same timeline, add vet visits and what was given, food changes and how her stomach responded, teething, seasons if relevant, and any appetite or energy dips. When a growth spurt coincides with a food change or a loose-stool week, the combined record lets your vet judge whether the pattern is ordinary puppyhood or something to check. Note adult weight expectations only loosely, based on your vet's view of her breed and parents, rather than chasing a chart that may not fit her individual build.
Use the record to steer training, not just store it
Review the log every few weeks and let it set your next training step. If recall is solid in the garden but untested at the park, that is the next milestone to build toward; if calm greetings lag while other skills race ahead, shift practice time there. Puppies develop unevenly, and the log stops you comparing her to a sibling or a social media puppy on a different curve. Share the timeline with your trainer or vet at appointments instead of reconstructing progress from memory in the car park.
Keep it light enough to survive busy weeks
The best puppy record is the one still being kept at six months. One page or one profile entry per week, a weight, a photo, two lines on training, is enough; elaborate scrapbooks collapse by week three. Store it where you will actually open it, backed up if it lives on a single phone.
