How to Track a Senior Pet's Decline (Without Losing Your Mind)

Why you cannot see it

Decline in an old animal is slow, and humans adapt to slow change without noticing. A dog who has quietly stopped doing six things over eight months looks normal to the person living with them. This is not inattention; it is how perception works. The only reliable fix is writing things down.

The four numbers that matter

Weight, weekly. Appetite, as a simple good or poor. Whether they managed the stairs or the jump today. And a one-to-ten on how the day went overall. Four data points a week, thirty seconds. Over three months that produces a trend line no memory can match.

What the trend tells you

A flat line means you are managing it. A slow decline means you have time to plan properly. A sudden drop over two weeks means book an appointment now. Most families discover that the picture in the record is clearer and often more urgent than the picture in their head.

Taking it to your vet

A written three-month record changes a consultation. It moves the conversation from I think he has slowed down a bit to here is the pattern. Vets can do far more with that.
