"Skin sore" is a coded term listed in 1,829 adverse event reports received by FDA, 0.1% of the database. Terms come from VeDDRA, the veterinary dictionary that FDA and drug companies use to code what a reporter describes.

140 reports listed it in the 12 months to March 2026, down 26% from 188 in the 12 months before. FDA posts reports quarterly with a delay of three to six months, so the newest months are incomplete and usually grow in later releases.

By active ingredient, the drugs named most often in those reports are milbemycin oxime + spinosad, fluralaner and frunevetmab. That order mostly follows how many reports each has overall; the table gives the term's share within each drug's own reports as well.

73.2% of the reports concern dogs, 23.8% of the reports concern cats and 1.1% of the reports concern horses. Of reports listing this term that state seriousness, 48.5% were classed as serious; 5.8% record a death or euthanasia among the outcomes.

Ordered by number of reports, which mostly tracks how many reports a drug has overall. Across the whole database the term appears in 0.1% of reports. A drug's presence in a report means the animal received it, not that it produced the sign; FDA states that these data cannot be used to compare one product with another. openFDA masks brand and manufacturer names in adverse event records, so the reports counted here cannot be attributed to a particular brand.

Questions about "Skin sore"

What does "Skin sore" mean in an adverse event report?

It is a VeDDRA dictionary term picked to code what the reporter described. The report's free-text description is not published by FDA and is not shown here.

How many reports list skin sore?

1,829 reports through March 2026 (0.1% of all reports), 140 of them in the latest 12 months.

Which drugs are named most often alongside this term?

By active ingredient: milbemycin oxime + spinosad (186), fluralaner (155), frunevetmab (153), selamectin (142) and afoxolaner (128). Drugs with many reports overall lead almost every term's list. Brands cannot be identified: openFDA masks them.

Which species are involved?

dog (73.2%), cat (23.8%), horse (1.1%) and human exposure (0.7%).

Does a drug appearing here mean it produced this sign?

No such conclusion can be drawn. FDA states that "there is no certainty that the reported drug or device caused the adverse event" and that the event "may have been related to an underlying disease, other drugs used at the same time or other non-drug related sources."

My animal shows this sign. What now?

This site cannot assess an animal. A veterinarian can; for an emergency, contact a veterinary emergency clinic. See the guide on when to call a vet.

Where this comes from. Counts are built from the openFDA Animal & Veterinary adverse event bulk files released 28 Sep 2026, which hold reports FDA's Center for Veterinary Medicine received through 31 Mar 2026. openFDA masks brand and manufacturer names in these files, so drugs are counted by the active ingredients each record discloses and no figure is attributed to a brand, application or company. Ingredient names, and the separate reference lists of approved products, follow the FDA Green Book as of 1 Oct 2026. Spelling variants of the same VeDDRA term (for example with and without a cross-reference note) are pooled. No report text, lot numbers or reporter details are published. See the methodology and sources; FDA's record is authoritative, and corrections are handled within five working days.
