Our dog tools are built on peer-reviewed veterinary standards from AAHA, AAFCO, and WSAVA. Here's what each tool does — and why it matters for your dog's health.
▶What is the most accurate dog age calculator?
Our dog age calculator uses the AAHA 2023 life stage guidelines, which account for breed size differences. Small dogs age slower than large dogs — a 5-year-old Chihuahua is roughly 36 human years, while a 5-year-old Great Dane is about 48. Try the age calculator →
▶How do I calculate my dog's daily calorie needs?
Our calorie calculator uses the AAFCO Maintenance Energy Requirement (MER) formula: RER × activity multiplier. RER = 70 × (weight in kg)^0.75. The multiplier adjusts for neuter status, activity level, and life stage. Calculate calories →
▶Which vaccinations does my dog need?
Core vaccines (required for all dogs) include rabies, DHPP (distemper, hepatitis, parvovirus, parainfluenza). Non-core vaccines like Bordetella and Leptospirosis depend on your region and lifestyle. Our schedule follows WSAVA 2024 guidelines. View vaccine schedule →
