Poisonous Flowers

  • Begonia: This tube-shaped, toxic plant causes irritation of the mouth and difficulty swallowing.
  • Foxglove: You might be wondering: is foxglove poisonous to dogs? The answer is yes. Foxglove is extremely toxic for dogs and can cause cardiac failure when ingested.
  • Lily of the Valley: Lily of the Valley causes diarrhea, vomiting, and a drop in heart rate.
  • Iris: Although a beautiful addition to a garden, iris should be avoided by dog owners. This deadly flower can cause irritation, drooling, vomiting, and lethargy.

Poisonous Shrubs

  • Rhododendron: A common shrub used in landscaping. It causes vomiting, diarrhea, drooling, paralysis, and potentially coma.
  • Oleander: This shrub causes vomiting and abnormal heart rate in dogs.
  • Peony: Peony causes vomiting and diarrhea if ingested in large amounts.
  • Holly: A dog who has ingested holly might demonstrate lip-smacking, drooling, and head shaking.

Poisonous Trees

  • Chinaberry: This tree causes seizures, low heart rate, and shock when ingested by dogs.
  • Horse Chestnut: Symptoms of ingestion include vomiting, diarrhea, convulsions, and coma.
  • Japanese Yew: A popular holiday tree, the Japanese Yew causes difficulty breathing, tremors, vomiting, and seizures in dogs.
  • Black walnut: Although the tree itself isn’t dangerous, the nuts of the black walnut tree can fall to the ground and mold very easily, upsetting a dog’s stomach if ingested.

Whether you’re celebrating Earth Day and Arbor Day, or just doing some springtime gardening, make sure that you are not planting poisonous plants and that anything your dog has access to is safe for them.

The classic Endura Pet Doors for Doors and Pet Doors for Walls are great for letting dogs come and go as they please. However, it is essential to ensure that the yard they now have unsupervised access to is completely safe for them and does not contain any plants toxic to dogs.

Once you’ve checked the yard for any potentially harmful plants, your dog is ready to explore! Check out our tips on treating seasonal allergies in dogs and cats to make sure outdoor time is as enjoyable as possible for your pet.
