Senior Pet Care Checklist

When Does My Pet Become Senior?

For dogs, the senior threshold depends on size. Small dogs (under 20 lbs) are considered senior at around 10–12 years. Large breeds reach senior status at 7–8 years. Giant breeds may be considered senior as early as 6 years. For cats, senior status typically begins at 7 years, with 11+ considered geriatric.

Why Twice-Yearly Vet Visits Matter

A year in a senior pet’s life is equivalent to 4–7 human years. Conditions like kidney disease, hyperthyroidism, and early cancer can develop and progress significantly in the months between annual check-ups. Twice-yearly visits in senior pets catch problems earlier — and early intervention almost always leads to better outcomes and lower treatment costs.

The Three Most Commonly Missed Senior Conditions

Kidney disease in cats is frequently missed until late stages because cats hide illness well and drink water from multiple sources, masking increased thirst. Arthritis in both dogs and cats is massively underdiagnosed because pets slow down gradually and owners attribute it to “getting old” rather than treatable pain. Dental disease causes chronic pain that affects appetite, behaviour, and organ health — yet many senior pets go years without a dental assessment.

Quality of Life in Senior Pets

The goal of senior care is not just length of life but quality of life. A senior pet with controlled pain, good nutrition, appropriate exercise, mental stimulation, and regular monitoring can have an excellent quality of life well into old age. The HHHHHMM scale (Hurt, Hunger, Hydration, Hygiene, Happiness, Mobility, More good days than bad) is a useful framework for monitoring quality of life in senior and palliative pets.
