Will one spot of raid on a flea on a dog harm him?

One spot of Raid, which is an insecticide, can potentially harm a dog if ingested, inhaled, or absorbed through the skin. Even small amounts can lead to toxicity, causing symptoms like drooling, vomiting, or difficulty breathing. It's important to keep pets away from areas treated with insecticides and to consult a veterinarian if exposure occurs. Always use pet-safe products specifically designed for flea control.
