Helping a dog with a sensitive stomach is all about whether things are settling over time - and that's hard to judge without a record. PetHealthLog lets you log probiotics and digestive supplements, record stool quality and the bad-tummy days, and see supplements and digestion on one timeline. Free, no account, works offline.
"Is his stomach actually better?" is hard to answer
Plenty of dogs have sensitive stomachs - on-and-off soft stool, the odd vomiting day, gurgly tummies. When you start a probiotic, a fibre supplement or a new sensitive-stomach food, the honest question is whether the good days are starting to outnumber the bad ones.
That's tough to judge from memory, because digestion swings day to day and a single firm stool doesn't mean much. Without a record it's easy to abandon something that was quietly working, or stick with something that isn't.
PetHealthLog is free, needs no account and works offline, so a quick stool note and a logged supplement each day build into a timeline that shows the real trend - the picture you and your vet can use to decide what to keep.
What the tracker actually does
Log probiotics and digestive supplements
Add each probiotic, fibre supplement or digestive aid by name and schedule, and tick it off day to day.
Record stool quality and upset days
Note stool quality and any vomiting, diarrhoea or gurgly-tummy days right next to the supplements, so the picture is honest rather than rosy.
See whether digestion is settling
Over a few weeks the supplements-and-stool timeline shows whether the good days are winning, instead of judging by a single day.
Track food changes alongside
Note a diet change or a new treat so you can see whether digestion shifts with it - useful when narrowing down a trigger with your vet.

Do probiotics help dogs with a sensitive stomach?
It varies a lot by dog and by product, which is exactly why tracking helps - by logging the supplement alongside stool quality, you can see whether the good days are increasing instead of guessing. For ongoing or severe digestive problems, your vet should rule out underlying causes rather than relying on supplements.
Can it track a food change too?
Yes. You can note a diet change or new treat on the same timeline as the supplements and stool quality, so it's easier to see whether digestion shifts with it - useful when you and your vet are narrowing down a possible trigger.
Does it work offline?
Yes. PetHealthLog is a progressive web app that works offline, so you can log a supplement or a stool note without a connection.
Is this a substitute for veterinary advice?
No. PetHealthLog is a record-keeping tool, not veterinary advice. Persistent vomiting, diarrhoea, blood in the stool or a dog that's unwell needs a licensed veterinarian, not just a supplement. The tracker simply records what was given and how your dog's digestion went.

When to contact a vet immediately
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).
