Holly is a Toxic Substance for Dogs
Leaf ingestion may result in mild stomach upset while ingestion of the berries may result in more severe stomach upset. Clinical signs include increased salivation, vomiting, lack of eating, diarrhea, head shaking, and smacking of lips. Most animals do well at home with minor medical care (inducing vomiting and withholding food). Please call a veterinarian for proper directions and at-home-care.
