The exact formula matters

Brand families change ingredients across scents, strengths, countries, and product forms. Keep the specific container and label rather than relying on a web image of a similar product.

Separate a lick from concentrate

Do not estimate from package size alone. Record the EPA registration number, active ingredient percentage, bait or concentrate form, amount missing, route, time, and dog weight.

Route changes the response

Swallowing, eye contact, inhalation, skin contamination, chewing packaging, and licking dried residue do not carry the same risks. Record every route that may have occurred.

Signs to watch for

Vomiting, drooling, tremors, weakness, agitation, abnormal bleeding, breathing changes, or seizures

Related items

Check the exact item or ingredient before assuming two similar exposures carry the same risk.

What to do next

Save the container, photograph the front and complete ingredient or active-ingredient panel, estimate the amount and time, note the route, and prevent more exposure.
