Simple Logging

From the Meter to the Trend

Measure your pet's glucose as usual, then log the reading and insulin amount in PetBG. Adjust your pet's glucose range using guidance from your veterinarian. Each reading is then marked as Critical Low, Low, Expected, or High within that range.

As the entries build up, you can review recent changes or see patterns over a longer period. The history gives you and your veterinarian useful context when reviewing your pet's treatment.

Easy Collaboration

Share the Care, Not the Paperwork

Send a sharing link to someone in your Care Team - your partner, a family member, or a trusted friend. They can open the same PetBG profile on their own device and add a reading whenever they care for your pet.

Each entry shows who added it, so everyone can see what has already been recorded and when.

Our Story

Our Mission With PetBG

When Kuzya was diagnosed with diabetes in 2024, we found a spreadsheet template created by a community of people caring for diabetic cats. It gave us a place to start, but as his history grew, the sheet became harder to manage and share with our veterinarian.

We built PetBG because we wanted a better way to care for him. Now we can both keep his history up to date and see how his glucose changes over time, without making the daily routine more complicated than it already is.

We cannot control everything about Kuzya's diabetes, but we can do our best to give him a good quality of life. We built PetBG to help caregivers of diabetic cats and dogs focus on what they can control.
