Death-Coded Outcome Share

Cross-breed median

3.1% of 14,058 terrier (unspecified) reports involved a death outcome.

How to read this number

Read alongside breed popularity, veterinary access, and owner awareness, these shape how many events ever reach the FDA. The comparison line marks the cross-breed median death-coded share (4.8%) among breeds with 50 or more reports; values above it suggest higher reporting bias toward severe outcomes, not necessarily higher true mortality.

Source FDA Center for Veterinary Medicine, openFDA adverse event extract (PlainBreed) · July 2026 extract

This histogram uses the same ≥50-report cohort as the highest death-coded share ranking. A higher share means more of this breed's reported events were death-coded, not a mortality rate for living animals.

Terrier (unspecified) among report-volume vs. death-rate peers

Every breed shown has at least 50 filed reports. Volume reflects how often a breed is reported, not how common it is; death rate is the share of a breed's own reports coded as a death outcome.

Terrier (unspecified): low death-coded share in the FDA CVM extract

Signature read: 14,058 reports place Terrier (unspecified) in the upper third of breed filing volume (#14 of 510). According to FDA CVM filings indexed on PlainBreed as of July 2026 extract, Terrier (unspecified) sits at #14 of 510 by report volume among all breeds and #13 of 298 among dog breeds, with 14,058 reports and 433 (3.1%) death-coded. On death-coded share among breeds with ≥50 reports, it ranks #227 of 275. Mean age at report: 5.8 years, average weight 11.6 kg (25.6 lbs).

Top reported signs: Vomiting (2,690), Emesis (1,488), Lack of efficacy (endoparasite) - heartworm (1,203). Most-referenced drug: Milbemycin Oxime + Spinosad (2,884 reports), followed by Ivermectin + Pyrantel As Pamoate Salt (1,460) and Pyrantel Pamoate;Sarolaner (1,184).

Outcome coding on 14,059 status-recorded reports is dominated by Recovered/Normal (34.2%). Annual submissions ranged 20-2,026 across 17 years on file.

Terrier (unspecified) Reporting Concentration Profile

Terrier (unspecified) is a high-volume FDA CVM cohort (14,058 reports) - enough filings to measure how concentrated the reaction and drug mix is, not just the headline totals. Across 20 named reaction terms in the stored top list, the leading three (Vomiting, Emesis, Lack of efficacy (endoparasite) - heartworm) account for 38.3% of listed reaction mentions. The Herfindahl index on that list is 0.084 (1.0 = a single reaction owns every mention; lower = a broader clinical mix).

On the drug side, 20 referenced products appear in the top list; the leading three (Milbemycin Oxime + Spinosad, Ivermectin + Pyrantel As Pamoate Salt, Pyrantel Pamoate;Sarolaner) cover 41.7% of those mentions. That multi-product footprint is the profile thin-report breeds cannot show - their pages stop at a short bar list because the sample cannot support a concentration read.

Outcome coding on 14,059 status-recorded filings splits roughly 3.1% severe (died or euthanized - 433 reports) versus 38.3% recovered or recovered-with-sequela (5,381). Read that split next to the 3.1% death-coded share above - both track reporting severity bias in a popular breed, not a proven mortality rate.

Peak filing year was 2024 (1,226 reports); the lightest year on file was 2010 (20). From 2024 to 2025, annual volume fell 12.2% (1,226 → 1,077). Year-to-year swings at this volume usually track product launches, owner awareness, and reporting campaigns more than sudden breed-health shocks.
