Senior Pet Care
Guidance on recognizing and managing the physical and health changes that come with aging in dogs and cats, and when to seek veterinary care.
Also known as Geriatric Pet Care, Aging Pet Health, Senior Dog Care, Senior Cat Care, Older Pet Wellness
Senior status doesn't arrive on a fixed birthday. A cat is generally considered senior from around 10 years old, while dogs vary widely by size: small breeds don't reach their senior years until 10 to 12, medium dogs around 8 to 10, and giant breeds like Great Danes can be seniors by six or seven. The AAHA describes senior as roughly the last quarter of a pet's expected lifespan, which is exactly why a one size fits all approach doesn't work.
What actually changes with age is more than the grey muzzle and the slower walks. Inside, organs like the kidneys, liver, and heart are gradually working less efficiently, and the immune system isn't as sharp as it once was. Cancer accounts for close to half of deaths in older dogs and around a third in older cats, and conditions like arthritis, kidney disease, diabetes, hypothyroidism in dogs, and hyperthyroidism in cats become far more common. None of this means aging itself is a disease. It means an older body has less reserve to cope when something does go wrong, so problems that a younger pet would shrug off can hit a senior harder and faster.
This is why vets generally recommend stepping up checkups to twice a year once a pet reaches its senior years, rather than the usual annual visit. A senior wellness exam typically goes beyond the standard check, often including bloodwork, a urinalysis, and sometimes blood pressure measurement, so early organ changes can be caught before they cause visible symptoms. Kidney disease is a good example: significant kidney function can be lost before a pet shows any outward signs, so bloodwork can flag it while treatment can still make a real difference.
Between vet visits, it helps to know what's worth mentioning at the next appointment versus what needs a same-day call. Keep an eye out for:
- Unexplained weight loss or gain, or a sudden change in appetite or thirst
- New lumps, bumps, or changes to the skin and coat
- Stiffness, reluctance to jump or climb stairs, or general slowing down
- Confusion, disrupted sleep, increased vocalising, or house-training accidents, which can point to arthritis, sensory decline, or cognitive changes similar to dementia in people
- Bad breath, bleeding gums, or other signs of dental disease
- Laboured breathing, prolonged vomiting or diarrhoea, or abdominal swelling
Cats in particular are good at masking discomfort, so subtle shifts like grooming less or avoiding a favourite windowsill are worth taking seriously rather than writing off as just old age.
None of this is about diagnosing your own pet at home. It's about knowing what's normal ageing and what deserves a proper look, so a vet who knows your pet's history can catch issues early, adjust diet and pain management, and help keep the senior years comfortable rather than reactive. The guides below go deeper into specific conditions and how to support your pet through this stage.
