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. Their weight can. Download PetScale today and give your pet the healthy life they deserve.
