A puppy changes fast in its first months, and steady weight gain is one of the clearest signs things are going well. PetHealthLog lets you log each weight, watch the growth curve climb, and keep weight, vaccines and vet visits on one timeline - free, with no account, and it works offline.

In the first months a puppy grows fast, and that steady upward climb in weight is one of the simplest, most reassuring signs that things are going right. The problem is that growth happens gradually. Weighed once and then not again for a fortnight, it is hard to remember whether your puppy gained a little, a lot, or barely at all - and a single number on its own does not tell you much.
What actually helps is the shape of the curve. A line that climbs steadily looks very different from one that flattens out or suddenly jumps, and those shifts are exactly what is worth noticing early. Loose notes on a phone or a scrap of paper rarely add up to a curve you can read at a glance, and they are easy to lose.
A puppy weight gain chart tracker turns those scattered numbers into one growth curve you can trust. PetHealthLog keeps it simple: it is free, it asks for no account, and it works offline, so the chart is there whether you are at home, at the breeder's, or at the clinic.
A growth log only helps if it is quick to update and easy to read as a trend. Here is how PetHealthLog handles both for a puppy.
Record a weight whenever you take one, in kilograms or pounds. For a small puppy where a few hundred grams matters, each dated entry keeps the detail you need.
Every weight becomes a point on a chart over time, so you read your puppy's growth as a curve climbing week by week instead of comparing numbers in your head.
A flat stretch or an unexpected jump stands out on the chart, so a change in your puppy's growth is something you notice in time to raise it, rather than after the fact.
A puppy's weight does not sit alone in those first months. Keep the growth chart, the vaccination series and vet visits in one place, so the whole early picture lives on a single private timeline.
Export a clean PDF of your puppy's records, including the weight history, to take to the vet. The growth conversation starts from an accurate chart instead of a guess.
Healthy growth varies a lot by breed and size, and a small-breed puppy and a large-breed puppy follow very different curves and reach their adult weight on different timelines. A weight chart is genuinely useful for seeing your own puppy's trend over time, but it does not tell you on its own whether that trend is right for the breed, or whether a particular weight is too high or too low.
PetHealthLog charts what you record and makes the trend easy to see, but it does not set a target weight or judge whether the growth is on track. Whether your puppy is growing well for its breed and age, and what its diet and feeding should be, are questions for your veterinarian. The tracker simply gives you an accurate history to bring to that conversation.
Weighing a puppy often happens away from a strong signal - at the breeder's, on a kitchen scale, or at a clinic counter. An app that needs a login and a live connection can stall in exactly those moments, right when you want to jot the number down before you forget it.
PetHealthLog stores everything locally on your device. There is no account to create, nothing is uploaded to a server, and there is no tracking. It opens instantly, shows the growth chart whether or not you are online, and keeps the data yours. Because it lives only on your device, you can export a backup any time and restore it on another phone.
Free, offline, and ready the moment you open it.

A tracker is for patterns over time — it is not for emergencies. Contact a veterinarian or an emergency clinic right away if your pet has difficulty breathing, collapses or cannot stand, has a seizure that does not stop or seizures that repeat, is straining to urinate without producing urine, has severe bleeding, or may have swallowed something toxic (see ASPCA Animal Poison Control).
