Lemongrass (Oil and Plants) isn’t Safe for Dogs
Don’t let your dog get close to lemongrass. This applies to both the plant and the essential oil product. The ASPCA states that lemongrass is toxic to dogs because it contains natural plant toxins like cyanogenic glycosides, which can release the dangerous hydrogen cyanide when digested.
Lemongrass, in essential oil form, will get easily absorbed into the dog’s blood stream if he gets a single lick of it so the bottle must be carefully stored away from the dog’s reach.
The lemongrass plant, on the other hand, only poses a danger if the dog actually chews and eats it. If you know that your dog doesn’t have a tendency to chew plants then it may be safe to have the lemongrass plants around at home or in the backyard. Otherwise, grow the plants in a location where your dog doesn’t have access.
