My Petland provides general educational information. It does not provide a diagnosis, treatment, prescription, prognosis, or a veterinarian-client-patient relationship.
Age estimates and life-stage descriptions are broad comparisons. Real animals vary with species, adult size, breed, genetics, health history, body condition, care, and environment. A calculator cannot examine your pet or decide what an individual change means.
Contact a veterinarian for decisions about nutrition, activity, preventive care, symptoms, tests, medication, or treatment. If your pet has trouble breathing, collapses, is unresponsive, has severe bleeding or major trauma, may have swallowed a toxin, cannot urinate, has repeated seizures, or develops another severe or rapidly worsening sign, contact a local emergency veterinary service now.
Examples on this site are not an exhaustive list of emergencies. When you are unsure, contact a local veterinary professional.
