Is Lemongrass Oil Safe for Dogs?
Why it’s a problem
Lemongrass oil is rich in citral, which irritates the mouth, stomach, and skin of dogs. Ingestion leads to vomiting and lethargy, and skin application can cause redness. Some flea sprays use it, but concentrated oil still poses ingestion and irritation risks because dogs groom themselves.
How to keep your pet safe
Never apply lemongrass oil neat to a dog, and keep bottles away from pets. Brief diffusion in a large, ventilated room is lower risk, but dogs should be able to leave. Ask your veterinarian before using any lemongrass product.
Warning signs to watch for
Drooling, vomiting, diarrhea, skin redness, pawing at the mouth, lethargy
When to call the vet
Call your veterinarian or a pet poison hotline if your dog swallowed lemongrass oil or has skin irritation. Rinse skin with mild soap and water.

Are lemongrass flea sprays safe for dogs?
Only products labeled for dogs and used exactly as directed. Concentrated lemongrass oil irritates skin and gut, and dogs lick their coats. Ask your veterinarian before switching products.
