Does your pet weigh what they should? PetScale is the smart, science-backed weight tracker built for pet owners who want more than a number on a scale. By combining your pet's species, breed, gender, and age, PetScale calculates a personalized healthy weight range and gives you the tools and guidance to help your pet reach — and stay at — their ideal weight. Because every pet is different. A 2-year-old male Labrador and a 9-year-old female Beagle don't share the same health benchmarks. PetScale knows that, and your recommendations reflect it. ~Breed & Profile-Specific Weight Tracking Add your pet's profile once and let PetScale do the rest. We factor in species, breed, gender, and age to determine what a healthy weight actually looks like for your pet — not an average animal. ~Weight History & Progress Charts Log weights over time and watch your pet's journey unfold. Easy-to-read charts show trends at a glance so you can celebrate progress and catch concerns early. ~Personalized Goal Recommendations Whether your pet needs to lose, gain, or maintain their weight, PetScale provides tailored tips on feeding portions, activity level, and lifestyle adjustments — updated as your pet ages and changes. ~Appointment Reminders Set reminders for vet visits, annual checkups, grooming appointments, dental cleanings, and more. PetScale keeps your pet's care calendar organized so nothing slips through the cracks. ~Supports a Wide Range of Pets & Breeds Dogs, cats, and more — PetScale is built to support hundreds of breeds across multiple species, so every pet in your home gets personalized attention. ~Clean, Simple Dashboard See your pet's current weight, goal weight, progress, and upcoming appointments all from one clean home screen. No clutter. No confusion. PetScale is perfect for: ~Pet owners managing a dog or cat's weight under vet guidance ~New pet parents learning what healthy looks like for their breed ~Multi-pet households tracking several animals at once ~Anyone who wants a simple way to stay on top of their pet's wellness Your pet can't tell you they're uncomfortable.
