Many common houseplants are toxic to dogs, including sago palms, lilies, aloe vera, and philodendrons. Some plants cause mild digestive upset, while others—like sago palms—can cause liver failure and death.
What to Do: Research plants before bringing them into your home, and keep toxic varieties out of reach. If your dog ingests a plant, call ASPCA Poison Control or your vet.
