Tail Time
Track Your Pup's Life Stage
Free · Designed for iPad. Not verified for macOS.
See your dog’s age in human years and learn what life stage they’re in — from playful puppy to wise senior — learn the best ways to care for them!
Tail Time — a cute, smarter dog age calculator.
The old "one dog year equals seven human years" rule is a myth. Dogs actually age much faster in their first two years and then slow down at a pace that depends on their breed, size, and weight. TallyTail does the math for you — with a warm, friendly design that makes it a joy to use.
WHY TAIL TIME?
Most dog age calculators use a single formula for every dog. TallyTail personalizes the result based on:
• Breed — 30+ curated breeds, each with realistic average lifespans
• Size class — Toy, Small, Medium, Large, and Giant breeds age differently
• Weight — because a 90 lb Lab ages faster than a 60 lb Lab
THREE WAYS TO CALCULATE
• Purebred — pick a breed, set the weight, and go.
• Mix — pick two breeds and TallyTail blends their size, lifespan, and aging rate.
• Mystery Mix — don't know the breed? Just enter the weight. Perfect for rescues and mutts.
