Many dog medications are dosed by weight, so the dose your vet sets is only right while the weight behind it is current. PetHealthLog keeps your dog's weight next to each prescribed medication, logs every dose you give, and keeps an accurate figure your vet can dose from - free, with no account, and it works offline. It does not calculate doses; your vet does.

When a medication is prescribed by weight, the dose your vet sets assumes a particular figure. The trouble is that a dog's weight moves - it creeps up over a quiet winter, drops with illness, and changes fast in a growing puppy. A dose set from a weight taken months ago can drift out of step without anyone noticing, simply because the number it was built on is stale.
That is why a current, written weight matters more than a remembered one. At a review your vet needs an accurate figure to dose from, and you need a clear record of which doses were actually given. "He's about the same as last time" is a guess; a logged weight next to the medication is a fact you can both work from.
This tracker keeps the weight and the medication record in one place. PetHealthLog is free, asks for no account, and works offline, so the figure and the dose log are there whether you are at home or at the clinic.
A record only helps if it is fast to update and easy to show. Here is how PetHealthLog handles both for weight-dosed medications.
Log your dog's weight whenever you have it, in the unit your clinic uses, and keep the history. A current figure is right there when a weight-based dose needs to be set or reviewed.
The weight sits on the same timeline as the prescribed medications, so the figure a dose depends on is not buried in an old note. When the weight changes, you and your vet can see it next to the drug it affects.
Tick off each dose as you give it. A dose that was not given stays visible instead of vanishing, so a missed or late dose is something you notice - and shared-care doubling is easier to avoid.
PetHealthLog never works out a dose for you. It holds the weight and the dose record your vet's plan relies on, leaving the dose itself where it belongs - with your veterinarian.
Export a clean PDF of your dog's records, including weight history and the medications given, to take to the vet. The dose review starts from an accurate weight and a clear history instead of a guess.
Dosing a medication by weight is not a single formula you can apply at home. It depends on the specific drug, the strength it comes in, your dog's condition and other medications, and your veterinarian's judgement - and getting it wrong in either direction carries real risk. That is exactly why this tool keeps to records and leaves the dose to your vet.
PetHealthLog does not calculate doses, does not suggest amounts, and is not a dosing calculator. It gives you a reliable place to keep an accurate weight, record what your veterinarian has prescribed, and log what you have actually given, so the figure your vet doses from is current and nothing about the medication record is left to memory. The dose, the timing and any change should always come from your vet.
The moment you need the weight is often the moment you are standing at the clinic scale or sitting in the exam room. An app that needs a login and a live connection can stall right when your vet is asking what your dog weighs and what has been given. A record you cannot open is no record at all.
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 latest weight and dose log 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).
