Senior Dog Health Monitoring at Home: What to Track Week to Week
You notice something. A slight hesitation before she jumps onto the sofa. A bowl that was mostly full by evening. A shorter walk than usual, followed by more sleeping.
Any one of these, on its own, is easy to file away as nothing. Dogs have off days. The weather changed. She's just slowing down a little — isn't that normal?
Sometimes, yes. But with senior dogs, the things that "seem normal" are often early signs of conditions that are highly treatable when caught at that stage and much harder to manage once they're obvious. The problem is that the changes happen slowly enough to be invisible to a brain that adjusts to a new normal day by day.
A simple log breaks that invisibility. Not a detailed medical chart — a five-minute weekly record of the things that actually move in a dog who's starting to age. This post covers what to track, why each item matters, and how to make it a habit that doesn't feel like a second job.

Why "She Seems Fine" Is a Risky Assessment for a Senior Dog
Dogs are exceptional at masking discomfort. It's a deeply wired behaviour — a dog in the wild who visibly signals pain is a vulnerable dog. So domestic dogs often continue to seem fine, continue to eat, continue to go on walks, continue to greet you at the door, well past the point where something is wrong.
The signs that do get through tend to be subtle behavioural and appetite changes rather than obvious physical ones. Slightly less enthusiasm for the morning walk. A fraction less food eaten at dinner. Choosing to lie down in the corner rather than in the middle of the room.
These aren't just personality quirks. Isolation and withdrawal are among the most reliable early indicators of pain in senior dogs. Appetite reduction is an early marker of a long list of conditions — kidney disease, liver disease, dental pain, gastrointestinal issues, nausea from undiagnosed conditions. Weight loss that amounts to only a few hundred grams per week is invisible to the eye but significant over a month.
The vet question that reveals how much this matters: "When did you first notice the change?" Most owners can't answer precisely. A log can.
The Six Categories Worth Tracking Week to Week
You don't need to observe all of these every day. A weekly summary — or brief daily notes that you review once a week — is enough to see patterns.
1. Appetite
Rate each week: is she consistently finishing meals, eating less than usual, or refusing food occasionally? Note which meals were affected and approximately how much she left.
Also worth noting: is she still interested in treats she normally loves? Does eating seem uncomfortable — chewing slowly, dropping food, or favouring one side? These suggest dental pain, which is common in senior dogs and easily missed because dogs rarely stop eating entirely.
A rating of "1 = eating normally, 5 = significantly reduced" on a weekly basis shows trends that daily variation obscures. A dog who eats 80% of her meals every single week for a month is a different picture from a dog who ate 100% for three weeks and then dropped to 60% this week.
2. Weight
This is the one most owners skip because it requires slightly more effort — and it is also the most valuable single data point for a senior dog.
The method: weigh yourself on a bathroom scale, then weigh yourself holding your dog. The difference is your dog's weight. Do this once a week, on the same day, at roughly the same time. Log the number.
Dogs can lose 10–15% of their body weight before it becomes visible to the eye, especially if they are larger or long-haired. At that point the loss has usually been happening for months. A weekly weight log catches the trend at week three or four, when it is still clearly reversible.
Weight gain matters too — in senior dogs, extra weight accelerates joint wear. For large and giant breeds (Labradors, German Shepherds, Golden Retrievers, Bernese Mountain Dogs, Great Danes), even modest weight gain adds meaningful load to hips and elbows that may already be showing wear.
3. Mobility
Rate each week how freely she is moving. Useful questions to reflect on:
- Does she get up stiffly after resting, and does she loosen up? How quickly?
- Is she hesitating before stairs, the sofa, or jumping into the car?
- Any limping, even intermittently, and on which leg?
- How did she move the morning after a longer walk — better or worse than usual?
Morning stiffness that improves with movement is a classic sign of arthritis. Stiffness that does not improve, or that is getting worse week on week, is a different and more urgent signal. Limping that comes and goes (rather than being constant) is often better described as "intermittent lameness" to your vet — that distinction changes the differential diagnosis.
For large breeds, any change in how your dog manages stairs or inclines is worth noting specifically. Rear leg weakness is particularly common in German Shepherds and can progress to significant mobility loss if not caught early.
4. Water intake and bathroom habits
A senior dog who starts drinking noticeably more water than usual is showing one of the most important early warning signs in geriatric veterinary medicine. Increased thirst (polydipsia) and increased urination (polyuria) together are early markers of kidney disease, diabetes, Cushing's disease, and several other conditions. The challenge is that "more water" is subjective unless you have a baseline.
You don't need to measure precisely. Note once a week whether drinking seems normal, slightly more, or significantly more than her usual pattern. Add a note if you're filling her bowl more often than usual.
Also log any changes in bathroom habits: more frequent urination, accidents indoors, straining, unusual consistency, or blood visible in stool or urine. These are not things to "keep an eye on" — they are prompt-your-vet-today-or-tomorrow signals.
5. Sleep, rest, and energy
Senior dogs sleep more than younger dogs — that is normal and expected. What's worth tracking is change from *her* baseline, not from a theoretical standard.
Once a week, reflect: is she sleeping more than last month? Is she restless at night — unable to settle, pacing, whining after dark? Nighttime pacing and whining in an older dog can point to pain (arthritis is often worse after a day of activity), cognitive dysfunction syndrome (sometimes called canine dementia), or a medical issue like a urinary tract infection causing a need to go out repeatedly.
Also note energy on walks: is she still eager to go, or is she pulling back earlier than she used to? Does she seem flat in the afternoon in a way that feels different from ordinary tiredness?
A weekly note of "energy: normal / slightly low / notably reduced" is enough to spot a trend.
6. Behaviour and social engagement
This is where the buyer language from senior-dog owners gets very specific: "she started isolating herself", "he's not following me around like he used to", "she just stares at the wall sometimes."
Withdrawal and isolation are pain signals. A dog who chooses to lie alone in a separate room when she used to always be in the middle of family activity has usually found that the activity causes discomfort she's trying to avoid. This is worth writing down with a date — not because you need to panic, but because "this started around week three of June" is useful information.
Also note:
- Is she startling more easily than before?
- Does she seem confused at times — standing in a room, not responding to her name, repeating behaviours?
- Is she still interested in play, sniffing on walks, greeting people she knows?
Cognitive dysfunction syndrome is significantly under-diagnosed in senior dogs because the early signs are diffuse and easy to attribute to "just getting old." They are also symptoms your vet cannot see in a 20-minute appointment. A brief behaviour log brings them into the room.
Linking Day-to-Day Tracking to Vet Visits
The reason to track between appointments is not just to have a diary. It is so that when something shifts — appetite dipping, weight trending down, a new mobility issue — you have a clear picture of when it started, how quickly it progressed, and what else changed at the same time.
That context transforms a vet conversation. "She's been a bit off" leads to a broad workup. "She's lost 600g over the past five weeks, her appetite has been consistently down about 30% since around the start of June, and she's been drinking noticeably more in the last two weeks" leads to a targeted panel.
