Poinsettia and dogs: mildly toxic, mostly hype

Pet Poison Helpline rates poinsettias as only mildly toxic to dogs and calls the poisoning greatly exaggerated. The milky sap irritates the mouth and stomach and sometimes causes vomiting.

What you may see after a chew:

  • drooling
  • vomiting
  • diarrhea, rarely
  • red, irritated skin or eyes where the sap touched

Keep the poinsettia, move it above nose height

A pot on the coffee table is at nose height for most dogs. Put it on a shelf or a windowsill, and pick up dropped leaves. Dog still at it? The ASPCA suggests a faux poinsettia.

Holly and mistletoe: the ones to keep away from dogs

Holly and mistletoe can cause stomach upset and heart problems if a pet eats them. Holly leaves and berries bring on vomiting and diarrhea, and the spiky leaves can hurt the lips and gums. Eating a lot of American mistletoe can drop blood pressure and leave a dog stumbling.

Keep holly up high and sweep up fallen berries. Hang mistletoe well above nose height and pick up any sprig that falls.
