How to Use the Pet Age Stages Chart

Select whether you have a dog or a cat and enter its age in years, then press Show Life Stage. For dogs, also pick the adult size, because small dogs stay adult longer and reach their senior years later than giant breeds.

Reading the stages

• Puppy or kitten: the first year, dominated by growth, vaccinations and socialisation.
• Junior: roughly the second year, when training and neutering decisions are common.
• Adult: the long prime of life, focused on weight, dental care and exercise.
• Senior and geriatric: more frequent health checks, joint support and comfort care.

Features

• Life stage from age, with a size-aware curve for dogs
• Human-age reference to make the stage easier to picture
• Stage-specific care checklist covering vaccines, dental, joints and more
• Works for both dogs and cats
