Question: are arbutus berries poisonous to dogs?
Answer: I went to the ASPCA Poison Control site: http://www.aspca.org/pet-care/poison-control/plants/?plant_toxicity=non-toxic-to-dogs and typed in Arbutus but it didn't come back with anything. Even if a plant is not highly toxic to cats/dogs, if they eat enough of a particular plant it could make them sick.
