🔬 How we built this care profile
The recommendations on this page are derived from a transparent rubric, not generic copy. Here is how we score every breed:
- Energy level (2/5): drives the 15-30 minutes daily daily exercise target and our living-space recommendation. We score based on AKC working-group classification and field-trial data.
- Grooming needs (2/5): determines brushing frequency (weekly) and whether we recommend a professional groomer. Scores reflect coat type (single vs. double, curly vs. straight) and shedding pattern.
- Trainability (2/5): drives our suitability rating for first-time owners. We score based on rank-and-recall data published by Stanley Coren and AKC obedience-trial outcomes.
- Health profile: we list the 4 breed-specific conditions Green Iguanas are most often screened for. Sources: OFA (Orthopedic Foundation for Animals) breed-statistics database, AKC parent-club health surveys, and the Morris Animal Foundation Lifetime Study where applicable.
📚 How our profile compares to other authoritative sources
We cross-checked our Green Iguana profile against the four most-cited reference sources. Differences below are reconciled in plain English:
| Source | What they emphasize | How we reconcile it |
|---|---|---|
| AKC Breed Standard | Conformation, working group, official temperament keywords | We pull breed-group classification and lifespan from the AKC standard but treat their temperament keywords as marketing — we add real owner-reported variance. |
| Wikipedia | Origin, history, breed development timeline | We use Wikipedia for origin and history facts, then verify against the parent-club site to catch outdated claims. |
| OFA (Orthopedic Foundation) | Statistical hip, elbow, eye, and cardiac screening rates by breed | Our health-issue list is anchored to OFA-flagged conditions; we keep the count honest rather than soft-pedaling known risks. |
| Morris Animal Foundation | Longitudinal lifetime studies (Goldens, Labradors, others) | Where a longitudinal study exists for a breed, we cite specific findings (cancer rates, age-of-onset patterns) inline rather than averaging them away. |
If you spot a contradiction between this page and one of the sources above, the difference is almost always whether the source is selling the breed (parent-club, breeder directories) or studying it (OFA, Morris). We optimize for the second.
How this page changes when the data changes
We re-derive every section on this page from Green Iguana attributes stored as structured data: size, weight, lifespan, energy/grooming/trainability scores (1–5), and a list of 4 breed-specific health risks. When a parent-club update or a new longitudinal study changes one of those inputs, every dependent recommendation across the page updates automatically — exercise duration, grooming frequency, cost estimate, insurance line, FAQ answers, and the Not-For-You block.
