Top Canine Aging Questions
How many human years is 1 dog year?
The first year of a dog's life is roughly equal to 15 human years. This is a period of rapid biological development, making a 1-year-old dog equivalent to a human teenager.
Is the "Rule of 7" a myth?
Absolutely. Scientific models prove that aging depends on weight. Giant breeds (90+ lbs) age significantly faster than small breeds after their second birthday.
When should I switch to senior dog food?
It depends on their "Human Age." Most vets recommend switching when your dog reaches the human equivalent of 55-60 years. Use our calculator above to find your dog's milestone.
How can I tell my dog's age by their teeth?
Puppies have tiny, sharp milk teeth. By age 2, teeth are permanent and white. By age 5+, you will see significant tartar and wear on the molars.
