FAQs
1. How do you calculate dog years to human years?
We use NIH-backed formulas: First year = 15 human years, second year = +9 years, each additional year = +4-6 years (varies by breed size). Small dogs age slower after year 2 compared to large breeds. Try Our Dog Age Calculator Now
2. Why do small dogs live longer than large dogs?
Large dogs age faster due to accelerated cellular stress. A Great Dane’s lifespan (6-10 years) is shorter than a Chihuahua’s (12-16 years) because their bodies mature and deteriorate more quickly.
3. How accurate is the cat age calculator?
Our cat age calculator follows AAFP guidelines, accounting for lifestyle (indoor/outdoor) and rapid aging in the first 2 years (1 cat year = 15 human years initially, then +4/year). Indoor cats typically live 2-3x longer. Try Our Cat Age Calculator Here
4. How to predict my puppy’s adult weight?
Use our puppy weight calculator by entering current age/weight and breed. Small breeds reach full size by 12 months, while giant breeds may grow until 18-24 months. Multiply 4-month weight by 2 for a rough estimate. Try Our Dog Weight Calculator Now
5. How many calories does my cat need daily?
An average 10-lb indoor cat needs ~200 calories/day. Our cat calorie calculator adjusts for weight, activity level, and life stage. Overweight cats should reduce intake by 20% under vet supervision. Try Our Cat Calorie Calculator Here
6. Why does my senior dog need different care?
Dogs age 5x faster than humans after year 2. A 7-year-old dog is considered senior (mid-50s in human years) and may need joint supplements, dental care, and biannual vet checkups to manage age-related conditions. Try Our Dog Age Calculator Here
7. Are your calculators vet-approved?
Yes! Our formulas are based on NIH and AAFP veterinary research. However, results are estimates—always consult your vet for personalized pet health advice.
