Top 10 Most Toxic Human Foods for Dogs
PlainPetFood ranks human foods classified as toxic to dogs by veterinary toxicology consensus, rendered live from the rankings table joined to foods and categories.

Research question
Among the 160 human foods catalogued in the PlainPetFood database, which are classified as toxic to dogs by ASPCA Animal Poison Control and aligned veterinary sources, and how are the toxic items distributed across food categories (fruits, vegetables, dairy, beverages, household items)?
Methodology
This ranking reflects the data currently in our database, sourced from the agency referenced in the citation below and updated automatically as new filings are processed.
Coverage and exclusions: the source agency occasionally suppresses values for confidentiality, small sample size, or quality control, and suppressed rows are excluded from this ranking rather than shown as zero. If the agency later revises a figure, the revised value replaces the old one automatically the next time our data is refreshed.
Data provenance: we pull each release as it becomes available and normalize it into our database; a later release simply supersedes the one before it, so readers never see a mix of old and new figures on the same page.
Comparability across years: when the source agency revises its release schedule, definitions, or coverage, we note the affected years on the methodology page so readers can compare like-with-like rather than across a changed measurement.
Editorial governance: a named editor reviews every ranking page before publication (see the byline above). If an entity disputes a figure attributed to it, corrections are checked against the official source record before any change is made.
Every number on this page can be traced back to its source by following the entity links and the citation below, so independent verification never requires anything beyond the original public source.
See the methodology page for the complete sourcing, source vintage, and column lineage.

Findings
Top entity in the ranking
The top-ranked record in this dataset is Alcohol, with a value of 1 on the Toxicity rank column. The full top-10 set is rendered in the table above. Every value comes directly from the current dataset; no number is hardcoded into this page. When the ASPCA Animal Poison Control Center + veterinary toxicology consensus publishes a revision, the ranking and the prose around it update automatically.
Distribution shape
The gap between the top-ranked record (1) and the 10th-ranked record (10) characterizes how concentrated the top of the distribution is. Where the top value is many multiples of the median value of the visible set, the population is highly concentrated, a small number of entities accumulate the bulk of the measured quantity. Where the top and bottom of the visible set are close together, the distribution is relatively flat across the top end. The full distribution beyond this top-10 cut is summarized in the aggregate context section below and explored in the linked entity profiles.
Aggregate context
Across the full population behind this ranking, here are the summary statistics: how many records exist in total, the sum of the ranking metric across all qualifying records, and the mean per-record value. The methodology page documents the exact filter applied (records with null or zero values on the ranking metric are excluded). This aggregate row is computed from the same dataset that powers the ranking above.
Source provenance
The records in this ranking originate from ASPCA Animal Poison Control Center + veterinary toxicology consensus, specifically the ASPCA Animal Poison Control reference list and aligned veterinary toxicology sources. PlainPetFood ingests the source vintage published by the agency and keeps this page current, there is no static export carrying stale numbers, and a newly published dataset is reflected here within hours. The methodology page documents the source URL, the vintage date, and the steps applied to prepare the data.
Why this ranking matters
Rankings like this one let a reader scan a population quickly and identify outliers, concentrations, and patterns that warrant deeper investigation. The detail pages linked from each entity in the table above give the full per-entity context: time-series history where available, related metrics from adjacent tables, and links onward to the underlying source records. The methodology page explains how an entity earns inclusion in the dataset and how the ranking column is computed at the source.
What this analysis cannot tell us
Toxic classifications are based on veterinary toxicology consensus drawn from the ASPCA Animal Poison Control Center, the Pet Poison Helpline, and peer-reviewed veterinary toxicology literature. The ranking is not a strict severity ordering: chocolate (theobromine), xylitol (artificial sweetener), grapes and raisins, onions and garlic (allium family), and macadamia nuts are all consensus-toxic at small ingested doses for most dogs, and the ranking among them does not imply one is uniformly more dangerous than another. Individual sensitivity varies by dog size, breed, age, underlying health condition, and amount ingested. Even foods labeled 'safe' on the broader PlainPetFood reference can become unsafe in large quantities, in dogs with specific allergies, or when combined with cooking additives (onion powder, garlic powder, xylitol-sweetened products). PlainPetFood is informational reference material, not veterinary advice. If a dog has ingested any food on this list, or any food the owner is uncertain about, the recommended action is to call the ASPCA Animal Poison Control Center at 1-888-426-4435 or contact a veterinarian immediately. Symptoms listed are typical reported symptoms; absence of immediate symptoms after ingestion does not mean the dog is safe.
