Pet Passport Status
The Dog to Human Years Studio is a specialized laboratory designed to translate the unique biological clock of your canine companion into human terms. Because dogs age at different rates based on their size and breed complexity—with giant breeds aging faster than small ones—our studio uses optimized veterinary models to provide the most accurate age equivalent. From the rapid growth of puppy weeks to the golden years of senior dogs, we help you understand every stage of your pet's life journey.
How to Use
- Select your dog's breed size: Small (under 20 lbs), Medium (21-50 lbs), Large (51-90 lbs), or Giant (over 90 lbs).
- Input your dog's current age using the high-precision slider or enter their Date of Birth (DOB).
- Watch the "Human Equivalent" dashboard update in real-time as you move the slider.
- Explore the "Life Bone Tracker" to see where your dog stands in their current life cycle (Puppy, Adult, or Senior).
- Read the "Human Milestone Comparison" cards to see what a person of the same equivalent age would be doing.
- Download or share your dog's "Pet Passport" status card with friends and family.

Tips & Best Practices
Smaller dogs typically live longer and enter "senior" stages much later than giant breeds.
The first two years of a dog's life represent the most significant developmental leap (equivalent to about 24 human years).
Giant breeds (over 90 lbs) are often considered "seniors" as early as 5-6 years old.
Regular vet checkups are especially important once your dog hits the "Senior" milestone on the bone tracker.
The "Puppy" phase is the best time for foundational social and behavioral training while their human equivalent age is still low.
