Toxic plants for dogs

A number of plants are poisonous to dogs. Consumption of these plants can cause a range of symptoms from vomiting to serious illness and even death in some cases.

Generally, dogs will stay away from plants that will harm them but sometimes curiosity and boredom get the better of them and they might nibble on your plants.

If you suspect that your dog has ingested a toxic plant, take it to a vet immediately. If you can, bring a piece of the suspected plant with you to the vet.
