Poisonous Plants


Many plants are toxic to dogs. For this reason, it’s always a good idea to discourage them from chewing on or ingesting any vegetation, especially the following plants.


The following plants are the most toxic to dogs and should never be made available to them under any circumstances:


  • Castor bean or castor oil plant (Ricinus communis)
  • Cyclamen (Cylamen spp.)
  • Dumbcane (Dieffenbachia)
  • Hemlock (Conium maculatum)
  • English Ivy, both leaves and berries (Hedera helix)
  • Mistletoe (Viscum album)
  • Oleander (Nerium oleander)
  • Thorn apple or jimsonweed (Datura stramonium)
  • Yew (Taxus spp.)
  • Any mushroom you cannot identify as safe


These types of vegetation are to be avoided for a variety of reasons. Do not plant them near your home or bring them inside as plants or cut flowers:


  • Amaryllis (Amaryllis spp.)
  • Autumn crocus (Colochicum autumnale)
  • Bleeding heart (Dicentra spectabilis)
  • Bloodroot (Sanguinaria canadensis)
  • Chrysanthemum (Compositae spp.)
  • Flower bulbs of any kind
  • Foxglove (Digitalis purpurea)
  • Jerusalem cherry (Solanum pseudocapsicum)
  • Larkspur (Delphinium)
  • Lily of the valley (Convallaria majalis)
  • Marijuana (Cannabis sativa)
  • Peace Lily or Mauna Loa Peace Lily (Spathiphyllum spp.)
  • Pothos (both Scindapsus and Epipremnum)
  • Rhubarb (Rheum rhaponticum)
  • Schefflera (Schefflera and Brassaia actinophylla)
  • Stinging nettles (Urtica dioica)
  • Tulip/Narcissus bulbs (Tulipa/Narcissus spp.)
  • Virginia creeper (Parthenocissus quinquefolia)


These tougher-leafed or woody specimens are also poisonous and should be avoided in and around your house.


  • Azalea
  • Box
  • Chinaberry tree
  • Horsechestnut
  • Laburnum
  • Oleander
  • Privet
  • Sago Palm
  • Rhododendron

    Are you saying you should not have any of the above around your home? Ridiculous. Train your dog to keep away from them...

    My dog, a mastiff, ate about 8-10 leaves from a lantana plant and within hours he almost died! Had to spend 2 days in the hospital hooked up to an IV and other monitors. You cannot train dogs to stay away from certain plants. Do you even have a dog?

    My dogs ate and chewed on Sago Palm bulbs today. Then vomited a few times. They both seem ok for now. We did take the small one to the vet. was told they would hospitalize him and cost us $1600. or more just for him. and there is still no guarantee he would live and be ok.
    We got Vitamin K capsules and Denamarin tablets from the vet and brought him him. He is sleeping and seems ok. I guess we will see what happens with 72 hours. Please Pray !

    We were digging up the bulbs from a larger plant and going to replant them elsewhere, not knowing they are poisonous, we were so busy we didnt even know the dogs were eating or chewing on them. I did read that the other part with the seeds is more poisonous. So i hope our dogs will be fine. I dont think they ingested that much, but cant be sure

    I just read a post on Facebook about heliotrope being poisonous to dogs. Causes liver damage? Is this true? I don't see it in the list. Thank you.
