Flowers and plants that are poisonous to dogs

The poisoning of your dog can be incredibly upsetting for the owner and hugely distressing for the animal. We run through the plants and flowers poisonous to dogs and what to look out for if you think your animal has been poisoned.

There are many factors to consider when choosing what plants to put in your garden: what will flower when, what needs the most TLC, what needs sunlight and what needs shade. One factor we might not necessarily think of immediately is the effect the plants and flowers we choose have on our animal companions.

While something may be just the right shade of yellow and flower at just the right time in the early summer, it might also be highly poisonous to dogs. It’s important to check which plants are toxic and which ones aren’t before you sow, to ensure your garden is only filled with dog-friendly plants. If you’ve moved to a new house with a garden, check what’s planted there before letting your dog out unattended. If you’re struggling to identify anything, there are apps available to help.

If you have a dog, you should never use cocoa mulch on your flower beds, as cocoa is potentially lethal to dogs. You should also be careful when using pesticides, weed killers or any other chemicals in your garden. Check the packaging carefully to make sure they are safe for use around animals. Many will advise keeping your animal indoors for a period of time after use.
