Observation tracking
Dog Symptom Tracker for Changes You Can Observe
Record what changed, when it started and what else was happening, so you can give your veterinarian a clearer history.
Direct answer: Buddylio is a dog health tracking app for recording owner observations on iPhone and Android. It is not a diagnostic symptom checker and does not suggest a condition or treatment.
Completely free: Every feature is included, with no ads, subscriptions, paid tiers, trials or locked tools.

What to write down
Use concrete language such as “left half of breakfast,” “slower on stairs” or “woke three times overnight.” Dates and specific observations are more useful than trying to name a condition yourself.
What Buddylio tracks
The daily check in covers appetite, mobility, comfort, mood, sleep and energy. You can add medication, weight, walks and a short note for context.
When not to wait for the app
Contact a veterinarian when your dog seems sick, is in pain or you are worried. For collapse, severe breathing difficulty, uncontrolled bleeding, repeated seizures or another emergency, seek urgent veterinary care.
Where this guidance comes from
The emergencies listed above come from veterinary guidance, not from anything the app determines.
