Daylilies are a common ornamental plant that grows abundantly in most of the United States. While daylilies are very toxic to cats, the American Society for the Prevention of Cruelty to Animals (ASCPA) reports that they pose no significant danger to dogs.

Daylily Toxins
-
Humans frequently experience mild gastrointestinal problems after consuming large amounts of daylilies, but this effect is relatively mild. The same compounds are severely toxic to cats, who may experience kidney failure after ingesting the flowers.
Nutrition for Dogs
-
Like humans, dogs are naturally omnivorous and may seek out plants for their nutritional value. Daylily flowers are a natural source of fiber and carbohydrates, and dogs may enjoy them as an occasional treat.
Side Effects
-
The fiber and irritant compounds in daylily may cause diarrhea or vomiting in sensitive dogs, especially when consumed in large amounts.
Allergies
-
Dogs with a rare daylily allergy may experience anaphylaxis after ingesting daylilies. Pet owners should use caution when allowing allergic pets near any ornamental plant.
Precautions
-
Daylilies may resemble flowers that are toxic to dogs. Pet owners should keep dogs away from ornamental plants unless the plant has been definitively identified.
