Sparkle ate ten berries from a bush/tree in our yard. After a call to poison control and a trip to the garden center, we determined they were hawthorn berries. They may or may not make her sick to her stomach, will either make her wired or drowsy, and are not poisonous unless she is allergic to them. I am shaky and upset after my trip to the garden center. Sparkle is unrepentant about eating the berries.
