How to Establish a Functional Mobility Baseline for Your Senior Dog

What is a functional baseline?

A functional baseline records what a dog can do now so later observations can be compared with the same task and context. It is most useful when it is specific: “stood from the same rug after the morning rest with one steadying hand” is more informative than “seemed worse.”

The baseline is not a score that labels a dog as healthy or unhealthy. It gives the veterinary team a clearer view of daily function outside the clinic, particularly when a problem is intermittent or difficult to reproduce during an appointment.^1,2

Which daily tasks should you track?

Track a small number of meaningful tasks such as rising, walking to the toilet area, eating posture, or entering the home rather than every possible behavior. For most families, one to three routine tasks are enough.

• Choose tasks your dog already performs in normal daily life.
• Choose tasks that matter to comfort, independence, or essential care.
• Avoid creating a difficult test solely to collect data.
• Write the task in observable terms instead of naming a suspected disease.

What should you record about getting up?

Record the starting position, surface, number of attempts, slipping, pauses, assistance, and what the dog can do immediately after standing.

Field	Example of a descriptive note
Date and time	August 12, after the morning rest
Starting position	Lying on the right side
Surface	Firm bed beside a non-slip runner
Attempts and movement	Paused, repositioned the front paws, then stood on the second attempt
Assistance	One hand used for balance; no lifting
After standing	Remained standing and walked to the water bowl

A note such as “back legs weak” may describe what you saw, but it should not be used as a diagnosis.

How should you take a useful video?

Record the dog's entire body and the full movement sequence in good light without repeatedly forcing the dog to perform a painful or difficult task. Capture a naturally occurring attempt when it is safe to do so.

• Include the paws, surface, starting position, and destination.
• Keep the camera still enough to see weight shifts and slips.
• Record a representative attempt, not repeated trials to obtain a “better” clip.
• Keep private household information out of the frame when possible.

Owner videos can provide useful information when the same activity does not occur in the clinic.^1,2

How often should you record?

Record often enough to show a trend without repeatedly testing or exhausting the dog. The right schedule depends on the concern and any plan set by the veterinary team.

Consistency matters more than volume. A short entry after a naturally occurring task can be more useful than a long diary with changing definitions. Record sooner when something clearly changes, and do not wait for a trend if urgent signs are present.

What counts as a meaningful change?

A meaningful change may involve new inability, more assistance, repeated failed attempts, increased slipping, altered pain-related behavior, slower recovery, or another health change.

Compare the same task and context when possible. A single difficult attempt after unusual activity may not describe the whole pattern, while repeated changes across familiar tasks deserve attention. The sudden-versus-gradual timeline guide will be linked here after its clinical review is complete.

Are owner questionnaires the same as a home log?

Validated owner questionnaires use standardized questions for defined clinical purposes, while a home log is an informal record of an individual dog's daily tasks.

Researchers and clinicians use tools such as the Canine Brief Pain Inventory, Canine Orthopedic Index, and Liverpool Osteoarthritis in Dogs questionnaire in appropriate settings. These tools have different validation evidence and intended populations.^4,6 A 2024 study also evaluated a timed up-and-go test in 89 geriatric dogs, but its study method and cutoff are not a household diagnostic test.⁵

AgeKind's observation format is not a validated clinical scale and does not reproduce any formal questionnaire.

How should the baseline be shared with the veterinary team?

Share a concise timeline, representative videos, the dog's medications and supplements, and the two or three daily tasks that matter most to the family. Include what changed, when it changed, the conditions in which it occurs, and the amount of help needed.

If the main concern is standing, return to the trouble-getting-up decision page. It places the observation in an urgency and next-step pathway.
