Poisonous Plants Toxic to Dogs Page 3

Here's the final list of common plants toxic to dogs (page 3).  We've tried to provide a beginning here but the complete list of plants toxic to pets can be found at the Animal Poison Control Center Website.

The best practice is prevention and common sense.

  • Keep your dog on a leash when out and about.
  • Gradually plant safe greenery around your house.
  • Place dangerous houseplants out of reach of your small dog or consider hanging baskets.
  • Keep in mind that plants are not the only things that can be toxic to your dog outside:  Pesticides, Fertilizers, Certain types of Mulch, and other chemicals
  •  Teach "leave it,"  "drop it," or "give it" to dogs if they accidentally pick up something they shouldn't have.
