Small animal Veterinarian, Dr Anne Fawcett was interviewed recently for a Pets4Life podcast about the common animal emergencies she sees in her clinic. Dogs and toxic plants in Australia was one of the many things Dr Fawcett talked about in the podcast. She mentions a plant Brunfelsia also known as Yesterday, Today and Tomorrow. This pretty flower causes serious illness including seizures in dogs.

Dr Chris Brown is also passionate about keeping dogs safe from toxic plants and other dangers in his guide to a dog-friendly backyard.

Keep your pet safe from toxic plants and household poisons is the topic of our three-part blog series.

Part one in our series is ‘Dogs and Toxic Plants in Australia’. While researching into toxic plants and possible effects in dogs, Kevin Crawshaw discovered there are many dangerous plants out there, which are mostly introduced species. The 21 plants in Kevin’s list appear to be commonly found in Australian suburban gardens, indoor plants and outdoor areas. Our list is a guide only and by no means fully comprehensive. Check out the resources below.

Generally, with a little investigation, and good common sense your canine friend will remain safe from toxic plants and enjoy exploring their world. Ask the vet if you’re unsure about the plants in your home.
