When a dog starts being sick or has the runs, the question that matters is "how many times, and is it getting worse?" PetHealthLog lets you log each episode with a time stamp, note what it looked like, watch for blood, and keep an eye on water intake - so you can see at a glance whether to monitor at home or call the vet. Free, no account, works offline.

A single vomit or one loose stool from a dog who is otherwise bright and bouncing around is usually something to watch rather than rush in for. What changes the picture is repetition - vets generally treat roughly three or more bouts of vomiting in 24 hours, or watery and frequent diarrhea, as the point where dehydration sets in fast, especially in puppies and senior dogs.
The problem is that during a stressful day the episodes blur together. Was that the second time or the third? Did it slow down after lunch or not? A vague memory is hard to act on, and it is exactly the detail a vet asks for first.
PetHealthLog is free, asks for no account and works offline, so each episode gets a time stamp the moment it happens. The 24-hour count is right there, the pattern is visible, and you have a real record instead of a guess when you call.
A symptom log only helps if it is fast to tap in the middle of a mess and turns scattered episodes into something you can read. Here is how PetHealthLog handles both.
Tap once to record a vomit or a bout of diarrhea, and it lands on the timeline with the time. No more counting on your fingers - the episodes line up so you can see how many there have been and whether they are spreading out or piling up.
The tracker shows how many episodes have happened in the last day, the number that often decides whether home monitoring is reasonable or it is time to call. You read the count instead of reconstructing it under pressure.
Add a quick note to each entry - watery or formed, food or yellow foam, and whether there was any blood. These details fade from memory within hours but matter a lot to a vet, so capturing them in the moment means you arrive with the picture.
Repeated vomiting and diarrhea drain fluids fast. Log water intake and note whether your dog is drinking, so dehydration - one of the real dangers here - does not creep up unnoticed between episodes.
Export a clean PDF of the episodes, their times, the notes and the hydration record. If you do end up at the clinic, the conversation starts from a real timeline instead of "a few times since this morning, I think."
General guidance from veterinary sources - when in doubt, call. The tracker helps you spot these, it does not decide them.
When a vet has said it is reasonable to watch at home, the usual approach is to let the stomach rest - often a short period without food, then small amounts of a bland diet such as plain boiled chicken and rice once the vomiting has stopped for a few hours. Owners commonly keep a few things on hand for this: an unflavoured electrolyte or rehydration solution made for dogs, a probiotic or pro-kinetic paste to help the gut settle, and a washable, wipe-clean mat for the inevitable accidents.

An upset stomach does not pick a convenient time. It happens at 2am, on a walk with no signal, in the middle of a busy morning. The last thing that should stand between you and logging the third episode is a login screen or a spinning loader.
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, lets you tap in an episode or check the count whether or not you are online, and keeps the data yours. You can export a backup any time and restore it on another phone.
Free, offline, and ready the moment you open it.
Start with PetHealthLogIf your dog has eaten something they shouldn't, log what was swallowed and when, then track vomiting, appetite and whether it has passed.
For diarrhea on its own, log each loose stool and watch the 48-hour mark while you decide whether to call the vet.
If grass eating is part of the picture, log each episode and whether vomiting follows to spot a pattern.
If your dog also goes off food, count the missed meals alongside the vomiting and diarrhea to see the full picture.
Schedule any dog medication, mark doses given, and catch the ones that slip - handy if the vet starts treatment after a bout of stomach trouble.
Keep a probiotic on schedule while the gut settles, and log how your dog's stomach and stools are recovering.
For dogs prone to flare-ups, track the low-fat diet and the symptoms that often start with vomiting.
Track meds, appetite and the upset stomach that sometimes follows an operation or a new medication.

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).
