Seven quiet changes in an older dog that are worth a checkup sooner than the next yearly visit

If your dog is eight or older and you notice a change in thirst, appetite, weight, sleep, breathing, mobility or behavior that lasts more than a week, book an exam rather than waiting for the yearly visit. Most of these changes have simple explanations, and the ones that do not are easier to manage when they are found early.

Older dogs rarely announce that something is wrong. They adapt: they skip the second flight of stairs, drink from the shower floor, or move their bed closer to the heater. Because the change is gradual, owners often notice it only when a visiting friend says the dog seems slower.

The seven changes we ask about

01Drinking more water

Refilling the bowl more often, or finding your dog drinking from new places, can point to kidney, hormone or blood sugar changes.

02Weight loss or gain

A few pounds matters on a small dog. Weigh at home monthly or ask for a free weight check.

03Sleeping in new places

Seeking out cooler or warmer spots can be a comfort or temperature change.

04Pausing at stairs or the car

Hesitation before a jump is one of the earliest signs of joint pain.

05Breathing faster at rest

Count breaths while your dog sleeps; more than about thirty a minute is worth a call.

06Night restlessness

Pacing or waking at night can be pain, a bladder issue or a change in thinking.

07Bad breath or dropping food

Dental disease is common after eight and can make eating uncomfortable.

Notes and videos help the doctor

A short written note helps more than you would expect. Write the change, when you first noticed it and whether it is getting better or worse. A phone video of your dog climbing stairs or getting up from a nap shows the doctor what is hard to reproduce in an exam room.

01.Note it

Write the change and the date you first saw it.

02.Measure it

Mark the water bowl, count resting breaths or weigh your dog.

03.Film it

A twenty-second video of stairs or standing up helps.

04.Book it

Ask for a senior exam rather than a quick recheck.

At the exam, the doctor usually suggests a blood panel and urinalysis. Together they explain most thirst and weight changes. Joint and mobility concerns may lead to a short course of pain relief or X-rays, and a dental exam often shows whether a cleaning would help.

The best senior exams start with the owner's notebook. You see your dog every day; we see a snapshot.

Questions owners ask

When does a dog count as a senior?
Most dogs are considered senior around eight, and giant breeds sooner, often by six. Small breeds may age more slowly, but we still recommend twice-yearly exams after eight.
Is slowing down just normal aging?
Some slowing is normal, but stiffness, hesitation and restlessness are often signs of pain, which can usually be eased with a plan made for your dog.
How often should an older dog have blood work?
We suggest twice a year for most dogs over eight, so changes show up as a trend rather than a surprise.
Should I wait for the yearly visit?
If a change lasts more than a week, call. A short exam now is easier than catching up later.
