Cognitive Change Observation Checklist

Canine cognitive dysfunction is diagnosed by ruling other things out. What you can usefully bring is an accurate description, not a conclusion.

Veterinarians assessing possible cognitive dysfunction work through a set of behavior categories in conversation with the owner. This checklist follows those categories so you can arrive with observations already organized. It deliberately has no score and no threshold, because the same behaviors are produced by pain, failing sight or hearing, medication effects and several medical conditions, and separating those needs an examination.

Who this is for: Owners preparing to raise cognitive change with a veterinarian.

A note on where these categories come from

The categories below follow the domains used in veterinary cognitive assessment, commonly summarized as disorientation, interactions, sleep and wake cycles, house soiling, activity, and anxiety. That framework is described in veterinary guidance including the AAHA senior care guidelines and the Merck Veterinary Manual.

This is an observation aid, not a clinical instrument. It does not reproduce any scored diagnostic questionnaire and produces no score, because a number generated at home would be misleading and is not what a veterinarian is asking you for.

What to observe, by category

CategoryExamples to look forWhat to write down
DisorientationStanding on the hinge side of an open door, getting stuck behind furniture, staring at walls, appearing lost in a familiar roomWhere in the house, time of day, how long, how she came out of it
InteractionsLess greeting, less seeking contact, or unusually clingy. Changed response to her name or to other petsWhat changed, with whom, and over how long
Sleep and wake cyclesAwake and restless at night, sleeping more by day, pacing after darkTimes, how often per week, what settles her
House soilingAccidents indoors in a previously reliable dog, or asking to go out and then not toiletingUrine or stool, awake or asleep, how soon after going out
ActivityRepetitive pacing or circling, aimless wandering, or a general drop in purposeful activityWhat the activity looks like, how long it lasts, what interrupts it
AnxietyNew fearfulness, distress when separated, restlessness in situations she used to tolerateThe trigger if you can identify one, and what helps

Rule these out first, with your veterinarian

Pain can resemble cognitive change. A dog who cannot settle, avoids stairs or seems withdrawn may be uncomfortable rather than confused.

Changes in sight or hearing can also cause bumping, startling or apparent disorientation.

Several medical conditions and some medications affect thirst, arousal, sleep and continence. Bring the current medication list, including anything started recently.
