Care for your pet with better numbers
From converting your dog’s age to human years to working out daily calories, these tools use the formulas veterinarians use, such as the resting energy requirement and AAHA life stages. They are a starting point, not a substitute for your vet.
If your pet may have eaten something toxic, call your veterinarian or an animal poison control line right away.
