Corrections changelog

Last updated:

This page lists every material correction made to a calculator or guide on Goodboy Atlas: the date it went live, the page it affected, what was wrong, and what the page says now. A material correction is anything that could change what a reader does — a wrong number, a wrong unit, an arithmetic slip, a threshold that didn't match its source, a citation that didn't say what the page claimed, or a claim that went further than the evidence.

When a correction is logged here, the affected page's byline ("Updated …") shows the date of its latest correction automatically, so the date you see on a page is the date it last materially changed. Typo fixes, rewording that doesn't change meaning, and layout changes are not logged.

The log starts in October 2026. Earlier changes were not recorded at the time, and I would rather leave that gap visible than reconstruct entries from memory.

How corrections happen

Corrections come either from re-checking a page against its cited source or from a reader's report. If you think something on the site is wrong — a dose, a unit, a range, a source that doesn't support the sentence citing it — use the contact page and include the page and what you expected. I check the claim against the source rather than defend it, and if the page was wrong, the fix is logged here. The standards the pages are held to are set out in the editorial policy, and the formulas are explained on the methodology page.

Pages on this site are written from cited published sources and are not reviewed by a veterinarian. Nothing here is a substitute for veterinary care: if your pet has eaten something toxic or is unwell, contact your vet or a pet poison line now — the help page lists the numbers.

Log

  • /dog-grape-toxicity-calculator — Corrected the grape threshold unit: the lowest dose in the Eubig 2005 case series is about 0.7 oz per kg (~19.8 g/kg), not "0.7 oz/lb (~32 g/kg)". The severity bands are now labelled as the site's own heuristic around "any ingestion = call your vet" rather than ASPCA / Pet Poison Helpline bands, and a ">90% recovery" figure was removed because the page linked no publication that reports it.
  • /dog-raisin-toxicity-calculator — Corrected the raisin arithmetic: a 25 lb (11.3 kg) dog reaches the lowest raisin dose in the Eubig 2005 series (about 2.8 g/kg) at about 21 raisins (32 g), not 15 or 20. Tartaric acid is now described as the suspected toxin, the severity bands are labelled as the site's own heuristic, and an "above 90% recovery" figure was removed because the page linked no publication that reports it.
  • /cat-grape-toxicity — Removed the claim that a 4 kg cat eating 3 raisins (about 1.1 g/kg) is "well above" the dog kidney-injury threshold. That dose is below the lowest dog raisin dose in Eubig 2005 (about 2.8 g/kg); the page now explains that no comparable cat data exist, so dog figures are not a safe line for cats.
  • /es/toxicidad-uva-gato — Same correction as the English cat grape page: a 3-raisin dose for a 4 kg cat (about 1.1 g/kg) is no longer described as above the dog threshold, and the dog raisin calculator is no longer presented as an upper bound for cats.
  • /dog-ibuprofen-toxicity-calculator — Relabelled the dose bands as approximate and aligned them to the commonly published thresholds (GI signs from about 50 mg/kg, kidney injury from about 175 mg/kg, neurological signs from about 400 mg/kg), replacing the earlier five-tier table. Removed per-band mortality and "no toxicity expected" wording, and any dose of 50 mg/kg or more is now flagged as call-now.
  • /dog-marijuana-thc-toxicity-calculator — Rewrote the CBD answer: it no longer says CBD oil is "generally safe" at low doses; it now says CBD products are unregulated, may contain THC and can interact with medications, so none should be given without a vet. Replaced the absolute claims that vets are "not mandated reporters" and that "vet-client privilege" applies in every US state with a plain statement that in most places vets are not required to report. Replaced a "~3 g/kg lethal dose" and a "765% increase" figure with what the cited Meola 2012 paper describes (two fatal cases after medical-grade THC butter) and a general statement on rising call volumes.
  • /cat-age-calculator — Unified the indoor/outdoor lifespan wording. The intro said indoor cats live "more than twice as long" and the lifestyle note said "nearly 3×"; both now state the model's own medians (about 15 years indoor-only vs about 6 outdoor-only) and note that published estimates vary.
  • /es/calculadora-edad-gato — Same indoor/outdoor correction as the English cat age calculator: "más del doble" and "casi 3 veces" replaced with the model's medians (about 15 vs about 6 years) and a note that published estimates vary.
  • /cat-calorie-calculator — The indoor/outdoor FAQ said outdoor cats "live half as long on average"; it now uses the same figures as the cat age calculator (median about 15 years indoor-only vs about 6 outdoor-only, published estimates vary).
  • /common-toxic-foods-for-dogs — Aligned the ibuprofen thresholds with the ibuprofen calculator (approximately 50 / 175 / 400 mg/kg for GI, kidney and neurological signs, replacing 50 / 100 / 250), added the Eubig 2005 lowest grape and raisin doses (about 19.8 g/kg and 2.8 g/kg), and changed "4-5× more concentrated" to roughly 4× for raisins.
  • /my-dog-ate — Same ibuprofen threshold correction as the toxic-foods page (approximately 50 / 175 / 400 mg/kg), grape and raisin rows now give the Eubig 2005 lowest doses, a 40 mg/kg example is no longer described as "already in the GI-ulceration band", and the "vets are not mandated reporters" line was replaced with advice to tell your vet honestly what was eaten.
  • / — Corrected the homepage calorie quick-reference: each column is now a direct multiple of resting energy requirement (RER × 1.2 / 1.6 / 2.0), and the life-stage multipliers in the note (intact adult about 1.8×, puppy under 4 months about 3.0×, puppy 4–12 months about 2.0×, inactive or senior about 1.2–1.4×) apply to RER, not to the table columns.
  • /dog-age-calculator — Retired about 105 templated per-breed dog age pages. The calculator only distinguishes size bands, so those pages repeated a handful of results under different breed names. Old breed URLs now redirect permanently to this calculator with the breed preselected, or to a hand-written breed page where one exists.
  • /cat-age-calculator — Retired about 45 templated per-breed cat age pages. The cat calculator gives the same result for every breed, so those pages added a breed name and nothing else. Old breed URLs now redirect permanently to this calculator with the breed preselected, or to the hand-written ragdoll lifespan page.
