🐾 How dog aging works: Small dogs age slower and live longer than giant breeds. First 2 years equal ~24 human years, then each additional year adds 4-7 human years depending on size.
💡 Pro tip: Regular vet checkups and proper nutrition help extend your dog’s healthy lifespan regardless of breed size.
