Senior Dog & Cat Care Checklist: Daily, Monthly and Twice-a-Year

Last updated: 20 August 2026

Somewhere around age seven, the job changes. A young pet mostly needs food, play and the occasional vaccine; a senior pet needs a system — more medications, closer watching, twice-yearly vet visits, and a caregiver who notices small changes early. This checklist organizes senior care into three rhythms: what to do daily, monthly, and every six months.

When "senior" starts

As a rule of thumb: around age 7 for most cats and dogs, and around 5–6 for giant dog breeds, which age faster. Nothing changes overnight — but this is the age when vets typically move to twice-yearly exams with bloodwork, because that's when kidney, thyroid, heart and joint issues start appearing quietly.

The daily checklist

• Medications given on schedule — senior pets are the most likely to be on several at once (joint, heart, thyroid, kidney), which is exactly when memory stops being a system.
• Appetite and water bowl. Eating less? Drinking noticeably more? Both are early flags (dental pain, kidney disease, diabetes).
• Movement. Hesitating at stairs, stiff after naps, no longer jumping to the usual spot — arthritis creeps in gradually and pets hide pain.
• Litter box / bathroom habits. Changes in frequency, accidents, or straining are worth noting the day they start.
• Gentle activity. Old pets still need movement and mental engagement — short walks and easy play keep joints and mind working.

The monthly checklist

• Weigh your pet and log it. Slow weight loss is one of the earliest signs of several senior diseases — a trend line catches what daily eyes can't. (Here's how to weigh a pet at home.)
• Parasite prevention — seniors still need their monthly flea, tick and heartworm doses, year-round.
• Medication supply check — count days left and reorder before you run out; refill gaps hit chronic meds hardest.
• Hands-on once-over: run your hands over the body for new lumps, check teeth and gums, nails (less activity = faster overgrowth), coat and skin.

Every 6 months: the vet visit

For seniors, most vets recommend a full exam twice a year — often with bloodwork, urinalysis, blood pressure and a dental check. Six months is a long time in an old pet's body; the point of the visit is to catch kidney disease, thyroid problems, heart changes and dental disease while they're still cheap and easy to manage. Bring your notes: the weight trend, medication list, and anything odd you logged since last time. That record is often more useful to the vet than the exam itself — here's how to keep it organized.

Changes worth writing down (and telling the vet)

• Drinking or urinating more than usual
• Weight loss without a diet change — or sudden weight gain
• Bad breath, dropping food, chewing on one side (dental pain)
• Stiffness, limping, reluctance to jump or climb stairs
• Cloudy eyes, bumping into things, not responding to calls (vision/hearing)
• Night-time restlessness, confusion, staring at walls, forgetting routines (cognitive decline)
• Any new lump, sore that won't heal, or persistent cough

None of these automatically mean something serious — but each is a data point, and "it started about six weeks ago, here's the log" gets better care than "sometime this year, I think."

Small home adjustments that help a lot

• Soft, warm bedding away from drafts — arthritic joints feel the floor.
• Ramps or steps to the couch, bed or car; a night light for dim hallways.
• Raised food and water bowls, and bowls on every floor so stairs aren't a requirement for a drink.
• A low-entry litter box for cats who no longer clear the high side comfortably.
• Keep the routine steady — predictable feeding, walks and sleep help aging pets (especially those with cognitive changes) stay confident.
