Every series below comes from a corpus/*.json view file the app serves as JSON -- nothing here is typed into the template. Each chart's caption names its source, n, and any caveats. A data table sits under every chart for readers without JS.

Median survival by breed

Median survival time (Kaplan-Meier), 155 breeds, UK primary-care dogs (McMillan et al. 2024, VetCompass, n=584,734). Hazard ratio vs. crossbred shown where the study gives it -- >1 means shorter-lived than a crossbred dog of the same age/clinic.

Cause of death by whether it was euthanasia (n=26,676) or an unassisted/natural death (n=2,487), UK dogs, Pegram et al. 2021 (Table 1). The two populations are not the same size -- percentages are of each population, not comparable bar heights.

NYC bite rate per 1,000 licensed dogs

Bites per 1,000 licensed dogs, 34 NYC breeds with a mapped spelling on both sides (all years combined). Dashed line: the combined rate across all mapped breeds (24.096/1,000). Preliminary -- self-reported breed labels, one city, active-licence denominator (licence compliance is well below universal, so every absolute rate overstates bites per dog actually owned). Compare breeds by relative_to_all_mapped, shown in the hover, not by the absolute rate.

Hip and elbow dysplasia by breed (OFA)

Hip and elbow dysplasia, percent evaluated abnormal, 169 breeds with at least one OFA evaluation count shown. OFA is a voluntary-submission registry -- breeders and owners choose whether to submit, so this is not a population prevalence estimate, and a small n is noisy; read n before comparing breeds.

Percent of dogs scored "high" fear and "high" noise sensitivity, 75 breeds with n>=50, Finnish pet-dog behaviour survey (Salonen et al. 2020, n=13,715 dogs total). Owner-reported questionnaire, not a clinical assessment.

AKC popularity rank by year (top 5, 2013-2025)

AKC top-5 registration rank by year, 2013-2025. Top-5 only -- AKC's site does not currently expose a full per-year ranked list beyond the top 5 (checked 2026-09-20; the full-list URLs referenced in AKC's own page content 404). Current #1: French Bulldog.

Claimed hypoallergenic breeds vs. measured allergen

18 breeds the AKC's own article names as recommended for allergy sufferers (a claim), next to Nicholas et al. 2011's measurement: 94.2% of 173 one-dog homes had detectable Can f 1 allergen regardless, with no statistically significant difference by "hypoallergenic" classification across 4 classification schemes tested (p > 0.05 for every comparison).

AKC-claimed hypoallergenic (18): Afghan Hound, American Hairless Terrier, Bedlington Terrier, Bichon Frise, Chinese Crested, Coton de Tulear, Giant Schnauzer, Irish Water Spaniel, Kerry Blue Terrier, Lagotto Romagnolo, Maltese, Miniature Schnauzer, Peruvian Inca Orchid (Hairless), Poodle, Portuguese Water Dog, Soft Coated Wheaten Terrier, Spanish Water Dog, Xoloitzcuintli

Nicholas et al. 2011: 94.2% of 173 one-dog homes had detectable Can f 1 allergen; no significant difference by hypoallergenic classification across 4 schemes tested (p > 0.05).

Popularity vs. health (derived)

AKC top-5 rank (most recent year held, 8 breeds) vs. OFA hip dysplasia % (rho=-0.2029, n=8) and McMillan 2024 median survival (rho=0.2824, n=8). Small n by construction -- AKC's own site exposes only a top-5 per year (see docs/sources.md); read this as a sketch, not a population estimate.

Purebred vs. mixed-breed lifespan (Urfer 2020)

Median survival time (Kaplan-Meier), US primary-care dogs, 3 independent clinics, n=20,970 (Urfer et al. 2020). No statistically significant difference between purebred and mixed-breed dogs (log-rank p=0.945) -- the finding here is the absence of a gap, not a gap.
