🔬 How we triage this symptom

The urgency rating and cause rankings on this page follow an explicit four-source rubric, not editor opinion. Here is what each contributes:

Merck Veterinary Manual: the canonical clinical reference for differential diagnosis. We use Merck for the cause categories (gastrointestinal, neurological, toxicology, etc.) and the typical urgency framing.
AVMA (American Veterinary Medical Association): policy-grade owner-facing guidance on when to seek care. We anchor our 'when to see the vet' criteria to AVMA-published checklists.
ASPCA Animal Poison Control: when toxin ingestion is on the differential, we cite ASPCA thresholds and the 24/7 hotline (888-426-4435) so the page is useful in a real emergency, not just for browsing.
Practitioner-published checklists: emergency-vet protocols and breed-specific symptom databases inform which causes we mark common, possible, and rare for rabbit. We do not pad the list to look thorough.

📚 How our triage compares to other authoritative sources

We cross-checked our rabbit hair loss guidance against the four most-cited references for owner-facing veterinary triage. Differences are reconciled in plain English:

Source	What they emphasize	How we reconcile
Merck Veterinary Manual	Differential diagnosis, mechanism, and treatment workflow for vets.	We translate Merck's clinical phrasing into plain triage language for owners, but we do not soften their cause rankings.
AVMA owner guidance	Plain-language criteria for when to call the vet vs. monitor at home.	Our 'When to See the Vet' bullets follow AVMA criteria. Where AVMA is conservative (default to call), we keep that bias rather than nudging owners to wait it out.
WebMD Pet / VCA / vet-clinic blogs	SEO-optimized owner explainers that summarize across causes.	These pages are useful for tone but we do not treat them as primary sources because their cause rankings often optimize for traffic, not clinical accuracy.
ASPCA Animal Poison Control	Toxin-specific exposure thresholds and emergency response calls.	If toxin exposure is on the differential, we route owners to the ASPCA hotline immediately and cite specific dose thresholds where they exist.

If our urgency rating differs from a generic owner site, the difference is almost always whether they are summarizing for SEO or sourcing from clinical references. We weight clinical references heavier — and we'd rather be cautiously conservative than tell a rabbit owner to wait when a vet visit is warranted.

How this triage updates

Every symptom page on this site is re-evaluated when the underlying clinical references update. The structured data behind this page includes the urgency rating, the ranked cause list (common/possible/rare), the 'when to see the vet' criteria, and the prevention checklist. When Merck updates a differential, AVMA tightens a triage rule, or ASPCA changes a toxin threshold, the urgency band, FAQ answers, and emergency callouts all refresh together.
