FatDog
Dog weight tracker
Log weigh-ins, food, treats, routines, vet reminders, and calorie goals in one calm place built for real life with your dog.
Our Story
FatDog started from a simple problem: it is easy to care deeply and still lose track of the small daily details that shape a dog's health. Weight trends, treats from different people, diet changes, reminders, and check-ins all matter more when they are seen together.
See progress across weeks and months instead of guessing from a single weigh-in.
Track meals, snacks, portions, calories, and who logged them for the active pet.
Keep feeding plans, vet reminders, and weigh-in due dates visible.
