Get started in under a minute
Open the free app and add your dog's profile - no sign-up or internet connection required.

Export your symptom history before vet visits so your veterinarian can see the full pattern.
Yes. The app is completely free to use, works offline, and does not require an account.
What is a luxating patella in dogs?
It is a kneecap that slips out of its normal groove. Logging how often it happens helps you and your vet understand the severity over time.
Can I track both back legs separately?
Yes. You can record which leg is affected for each episode so you can compare patterns between the left and right knee.
Does my data stay private?
Your records are stored on your own device. Nothing is shared unless you choose to export and send it yourself.
Can this app diagnose or treat my dog?
No. This app is only a record-keeping tool and is not a substitute for professional care. Always consult a licensed veterinarian for diagnosis, grading, and treatment decisions.
Informational only - not veterinary advice. PetHealthLog helps you keep records and stay organised, but it does not diagnose, prescribe, or decide your pet's treatment. Diagnosis and any plan should be decided with a licensed veterinarian.

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).
