Take the Same Photo Every Month

Take three photos of your pet, from the same angles, on the same day each month.

It takes about ninety seconds, costs nothing, and it will show you things you cannot see by looking at them every day.

Why daily observation fails

Gradual change is invisible to continuous observation. This is not a failure of attention — it's how perception works. Your reference point updates alongside the change, so nothing ever appears different from yesterday.

It's the same reason you don't notice your own hair growing, or a child getting taller.

The consequence is that owners routinely fail to notice quite dramatic changes over months, and then are shocked by an old photo.

A photograph freezes the reference point. Two photos six months apart show you what six months of looking couldn't.

The three shots

1. From directly above, standing.

Stand over them, phone held level, shooting straight down. This shows the waist — the narrowing behind the ribs — which is the clearest indicator of body condition and one of the first things to change.

2. From the side, standing, full body.

Get down to their level rather than shooting downwards. This shows the abdominal tuck, the topline, the prominence of the spine and hips, and overall condition.

3. Face on.

Shows muscle over the head — temporal muscle wasting, which appears above the eyes and along the top of the skull, is an important and easily-missed sign of illness in older animals. Also shows eyes, symmetry, and any facial swelling.

Optional but useful:

• Any lump, close up, with a coin or ruler beside it for scale
• Any skin lesion or patch
• A short video of them walking away from and towards the camera on a hard floor

Doing it consistently

Consistency is what makes the comparison work.

• Same lighting if possible — outdoors in daylight, or the same room
• Same distance and angle
• Standing squarely, not sitting or leaning
• Same time of month. Attach it to the monthly weigh-in.
• No filters, no portrait mode. You want an accurate record, not a flattering one.
• Get the whole animal in frame

A tip that helps: keep last month's photo open on another device and match the framing.

What it reveals

Weight loss. The most valuable. Combined with the scale, photos tell you whether loss is fat or muscle, which matters clinically.

Muscle wasting. Distinct from fat loss and more concerning. Look at the muscle over the skull, the shoulder blades, the spine and the hind legs. Loss here — sarcopenia or cachexia — is associated with kidney disease, heart disease, cancer and chronic inflammation. It's one of the signs vets look for specifically, and it's very hard to spot day to day.

Abdominal enlargement. A belly that's getting rounder while the spine becomes more prominent is not weight gain — it's often fluid accumulation or organ enlargement, and it's significant.

Postural change. A hunched back, a low head carriage, a shifted weight distribution, or standing with the hind legs further under the body. These often indicate pain.

Coat changes. Thinning, dullness, symmetrical hair loss on the flanks (which suggests hormonal disease), or areas being over-groomed.

Lump growth. With a coin for scale, this becomes measurable rather than impressionistic.

Facial changes. Swelling, asymmetry, a drooping eyelid or lip, a changed head carriage. Subtle neurological changes often show up here first.

Third eyelid protrusion, sunken eyes, or a change in pupil size.

Organising them

Keep them in a dedicated album on your phone, named for the pet. Most phones let you create an album in seconds.

The photos are date-stamped automatically, so you don't need to do anything else — but if you're keeping them elsewhere, name the files with the date.

The point is to be able to pull up March and September side by side. That comparison is where the value is.

When to look back

• Every three months, deliberately compare against three months prior
• Any time you're worried about weight or condition
• Before a vet appointment — bring the photos
• Whenever someone comments that your pet looks different. Visitors who see your animal infrequently are much better at spotting change than you are, and if someone says "has he lost weight?", believe them and check.

Bringing them to the vet

This is genuinely useful and vets appreciate it.

A vet seeing your animal for the first time in a year has one data point. Showing them a sequence — same angles, monthly, over eight months — gives them a trajectory, and trajectory is what determines urgency.

It's especially useful for:

• Documenting weight and muscle loss
• Showing lump growth rates
• Demonstrating a change in posture or gait
• Skin conditions that come and go

The other reason to do it

Beyond the clinical value, there's this: people who lose a pet almost universally say they wish they had more photos, and specifically more ordinary ones — not birthday portraits, just the animal existing.

A monthly photo log produces exactly that, incidentally, over years. Several people have told us the health log became the thing they were most glad to have afterwards.

Take a video with sound occasionally too. That's the one people miss most.

Start this month

Pick a date. Take three photos. Put them in an album.

Members do this inside the community tracker so the photos sit alongside the weight and the notes on the same date, and the comparison view is built in. But a phone album works perfectly.

The habit is what matters. The first photo is worth nothing on its own — and everything six months from now.
