Key Takeaways
- Lemongrass is not recommended for dogs
- The tough, fibrous plant can cause intestinal obstruction
- Lemongrass essential oil is toxic to dogs
- Small ingestions may cause vomiting or diarrhea
- Keep lemongrass plants and essential oils away from dogs
Is Lemongrass Safe for Dogs?
Lemongrass is not considered safe for dogs and should be avoided. While not as toxic as some plants, lemongrass poses several risks that make it unsuitable for canine consumption. The fibrous nature of the plant can cause physical digestive problems, while the essential oil concentration can lead to more serious toxicity.
The ASPCA lists lemongrass as potentially toxic to dogs, noting that ingestion can cause gastrointestinal upset and that the essential oil is particularly dangerous. Dogs who consume large amounts of the plant material may develop intestinal blockages due to the tough, indigestible fibers.
If you grow lemongrass in your garden, consider fencing it off or placing it where your dog cannot access it.
Nutritional Value
Lemongrass does contain some beneficial compounds including:
- Citral: The primary active compound with antimicrobial properties
- Antioxidants: Various plant compounds
However, these potential benefits are far outweighed by the risks for dogs. There are safer ways to provide antioxidants without the dangers of lemongrass.
Risks and What to Avoid
Intestinal blockage: The tough, fibrous stalks of lemongrass can clump together in the intestines and cause obstruction, which may require surgical removal.
Gastrointestinal upset: Even small amounts can cause vomiting, diarrhea, and loss of appetite.
Essential oil toxicity: Concentrated lemongrass oil is dangerous to dogs. It can cause liver damage, neurological symptoms, and severe gastrointestinal distress if ingested or absorbed through the skin.
Photosensitivity: Some compounds in lemongrass can increase sensitivity to sunlight.
Respiratory irritation: The strong scent can irritate sensitive respiratory systems.
How Much Is Dangerous?
There is no established safe amount of lemongrass for dogs. Even small quantities can cause stomach upset in sensitive individuals. Large amounts (multiple stalks or significant portions of the plant) increase the risk of intestinal blockage.
Essential oil exposure is dangerous at any concentration. Never apply lemongrass oil to your dog’s skin or allow them to ingest it.
When to Call Your Vet
Contact your veterinarian or ASPCA Poison Control (888-426-4435) if your dog:
- Eats any amount of lemongrass plant material
- Is exposed to lemongrass essential oil
- Shows signs of gastrointestinal distress (vomiting, diarrhea, loss of appetite)
- Appears to have abdominal pain or bloating
- Shows signs of lethargy or depression after exposure
Seek immediate veterinary attention if you suspect intestinal blockage (repeated vomiting, inability to keep food down, abdominal pain, constipation).
