toxic plant listDid you see this article on poisonous plants for pets? If you did, you were probably shocked to discover how many of these are in your garden. Time to find out which ones are the greatest problem.

We researched our patient files from 1999 to 2015 and to our surprise found plants were a very uncommon cause. Here is the full list of all pet poisonings from most to least common. We’ve included every known plant poison we’ve seen. Also visit our page on poisonous foods for pets.

Causes Of Poisoning In Pets

Remember, if your pet eats any of these, a vet inducing vomiting within 30 minutes plus administering activated charcoal should prevent any adverse effects.chocolate dog poison

Chocolate (80 cases)

Chocolate is the number one poisoning we see, mainly in dogs, and deaths do occur. Chocolate is tasty, poisonous and commonly left around the house.

rat poison and dogs

Rat Poison (66)

Did I just say tasty, poisonous and commonly left around the house? Take care when visiting other people’s homes; dogs will find it! Rabbits are also poisoned by rat baits. Read what to do if your dog eats rat baits here.

Most onion, leek, shallot or garlic poisoning is caused by feeding inappropriate leftovers. Onion toxicity is probably more common than we realise as the symptoms of anaemia are often missed. Read more about onion poisoning in dogs here.

Snail Bait (13)

Grapes & Sultanas (12)

compost toxic to dogsCompost (12)

Did you know how toxic garden compost can be? All those lovely moulds on spoiled food produce toxins which (just like toadstools) can kill quickly. Keep it secure!

Fertiliser (10)

Typically only puppies are silly enough to eat these. Quietly dispose of them when puppy isn’t looking to avoid making it a game.

Ibuprofen (8)

Since macadamia nuts are usually coated in chocolate, they truly represent a dog poisoner’s dream. Eat them before the dog does.

Cannabis (3)

We’ve noticed a large reduction in cannabis poisoning in pets since the early 1990s. Exposure occurs when people make it into edible forms like butter or biscuits.

Lilies are truly bad news around cats. Tiny nibbles from leaves can kill by kidney damage. If you have indoor cats, offer them Cat Grass and never allow access to lilies.

Melia azedarach berriesWhite Cedar (3)

Melia azedarach, often called the white cedar, is a very common street and garden tree in Adelaide. It produces toxic yellow berries which the occasional dog will eat.

oleander dog poison

Oleander (1)

This single poisoning was a puppy chewing on the garden plants. Poisonous plants usually taste terrible and I’m sure oleander is no exception.

Ivy (1)

As you can see, plant poisonings are very rare in Adelaide compared with other household pet poisons. However, we also see a lot of unexplained gastrointestinal upsets which we suspect in many cases to be caused by eating something stupid. Therefore some of these could be caused by nibbling garden plants. The good news is that these dogs and cats usually make uneventful recoveries.

Brunfelsia dog poison
Brunfelsia (Yesterday, Today, Tomorrow)

Young puppies are the most likely pets to chew up plants; for this reason we don’t advise you leave them outside alone. However, as you can see from our list, the risk isn’t great. It’s good to know most poisonings occur when animals are given access to toxins in a flavoured form.

Other Poisonstoxic sea hare

Outside of Adelaide, South Australia there are likely to be other dangers your vets can warn you about. Examples include Yesterday, Today, Tomorrow (Brunfelsia) which grows better in more humid areas, antifreeze poisoning in colder areas, sea hares washed up on Yorke and Eyre Peninsula beaches (pictured) or 1080 foxbaits near farms and national parks.
