Sightline · For vets
A better answer to
"how has she been?"
Sightline turns an owner's weekly observations into a trajectory and a one-page Report you can read in sixty seconds. The methodology is published in full, and every score on the page is traceable to the algorithm version that produced it.
It is a tracking and record-keeping tool an owner runs at home, not a diagnostic device. What reaches you is structured longitudinal data to read alongside your own examination, never in place of it.

You see snapshots. The owner sees every day, and recalls little of it precisely.
A fifteen-minute consult, often weeks or months apart, is a thin slice of a pet's life. The owner has the rest of it, but memory smooths change out: they remember yesterday far more clearly than last month, and the slow declines that matter most are the hardest to recall and the easiest to miss.
Pain in dogs and cats is famously underdetected, and behavioural change is subtle. The owner is the highest-yield observer of it, yet asking them to summarise weeks of observation from memory in the consult room rarely captures what actually happened.
Sightline gives that observation a structure. The same short assessment each week, scored the same way and plotted as a single line, so you and the owner are reading the same picture rather than reconstructing it.
Built and signed by
Sightline is built by ConciergeVet, a UK veterinary practice run by Alastair and Claire Greenway. Both have spent years asking owners variations of "how has she been?" in the consult room, and watching how hard that question is to answer well from memory alone.
What you see when an owner shares a Report
Four things on the page.
The trajectory
The Sightline Score plotted across the weeks of the reporting window, so the direction of travel is visible at a glance rather than inferred from a single day.
Lower is better. A treatment effect, a flare, or a slow decline shows up against a real baseline, not an impression.
The per-domain breakdown
The eight weighted domains behind the latest number: mobility, comfort and rest, demeanour, activity, owner goals, eating, toileting, grooming.
Mobility and comfort carry the most weight, in line with the LOAD factor-1 dominance and the CBPI severity-over-interference ratio.
Owner-defined goals
Up to five activities the owner chose to track themselves, in the CSOM tradition, so what matters to that household is on the page next to the composite.
Captures the things a generic instrument cannot anticipate: the walk, the sofa, the stairs.
The audit trail
Every score is stamped with the scoring-logic version that produced it, and the full methodology is published, so nothing on the page is a black box.
You can trace any number back to the exact weighting and the published rationale behind it.
How the Score is built
Eight domains, weighted from the literature.
Each week the owner answers a short adaptive subset of a 44-item assessment, branching on species, age, conditions and concern level. Each item lands in one of eight clinical domains, and a weighted composite produces the Sightline Score on a 0-to-100 scale where lower is better.
The weighting is a clinical judgement by the founders, derived from a structured audit of the published canine and feline pain and quality-of-life literature: LOAD factor analyses, CBPI eigenvalue ratios, the VetMetrica HRQL taxonomy, the Belshaw scoping review, and the WSAVA 2022 and AAHA 2022 frameworks.
The numeric Score is withheld from the owner until a baseline exists at the third weekly check-in. Before that, they see the trajectory and the five-band qualitative read, not a single number to anchor on. The point is to discourage single-point reactions and keep attention on the curve.
Validated instruments, used as published
Separate from the Score, and credited to their authors.
The Sightline Score is a first-party composite and is not an input to any of the instruments below. Where they are clinically relevant and their licence terms permit, these established, independently validated scales run alongside it, used as published and credited to the people who built them.
Feline Grimace Scale (FGS)
Université de Montréal
An independently validated acute-pain scale for cats, surfaced where photo-based grimace scoring is relevant. It runs on its own and reports its own score.
JOURNEYS
Dr Katie Hilst
An independently validated quality-of-life scale, available weekly in quality-of-life focus mode. A separate instrument with its own scoring, not folded into the Sightline Score.
Pawspice (HHHHHMM)
Dr Alice Villalobos
An independently validated end-of-life quality-of-life scale, available on demand. Reported on its own terms, alongside the Score rather than inside it.
The one page that reaches you.
The Sightline Report is a short, dense PDF formatted for clinic: the Sightline Score and trajectory, the per-domain breakdown behind the latest number, the owner's tracked activities, and their own cover note. Sized to be read in sixty seconds, built to be read alongside the clinical record rather than in place of it. You can see a real sample without an account.
Honest about what it is
A first-party composite, not a validated instrument.
The Sightline Score is informed by the published veterinary literature on pain and quality of life, but it is not itself externally validated, and it is not presented as one. The clinical value is in the trajectory, not the absolute number. Wherever the Score appears, this framing appears with it.
Sightline is a tracking and record-keeping tool, not a diagnostic device and not veterinary advice. MRCVS oversight describes how Sightline is designed and maintained in general, not individual clinical advice about a particular pet, and using Sightline does not form a vet-client relationship.
Questions
What clinicians usually ask.
Do I need an account to read a Report?
No. An owner can share a Report as a PDF, or share a read-only link, and you can open either without signing up. A sample is public on this site.
Is the Sightline Score validated?
No, and we never claim it is. It is a first-party clinical composite informed by the published literature, designed to make trajectory legible week on week. The validated instruments we surface (FGS, JOURNEYS, HHHHHMM) are separate, run on their own, and are not inputs to the Score.
What does a rising score mean?
A higher score means more reported signs of pain or reduced quality of life, so a rising line is a prompt to look closer. It is not a diagnosis or a recommendation to change treatment; the clinical judgement stays with you.
How is the weighting decided?
By the founders, from a structured audit of the validated canine and feline literature, and published in full with a changelog. Every score carries the scoring-logic version that produced it, so the weighting behind any number is traceable.

PAWSCHECK
Where Sightline captures the owner's weekly observation, PAWSCHECK analyses gait from a smartphone video and gives a vet-reviewed objective read of how the pet is actually moving.
PetsLikeMine
The clinical measurement sits in Sightline; the daily living-with-it support sits in PetsLikeMine, a community for owners managing a condition between appointments.
