During the holidays, plants can play a prominent role in festive decorations, but
poinsettias, holly, and mistletoe are all no-nos for your dog. If ingested, poinsettias could give your dog a case of mild to moderate gastrointestinal upset. Both holly and mistletoe, along with their berries, are highly toxic and could be fatal if eaten. Keep your dog feeling fine this season by placing these plants out of reach so he is not tempted to explore them.
