With summer now finally here, it’s likely both you and your pets will want to be out in the garden more to enjoy the warmer weather.

But did you know the average garden is packed with poisonous plants for dogs and cats?

Whilst keeping your pet away from poisonous plants is far from easy, especially if your dog or cat has a habit of roaming far and wide, here are a few species to keep an eye out for closer to home.

Which are the most poisonous plants for dogs and cats?

Rhodedendron: Not only is this toxic to cats and dogs, it can also be dangerous for horses. Eating just a few leaves can cause digestive problems, excessive drooling, loss of appetite, diarrhea, depression and even a loss of coordination. In severe cases, it can cause a weak heart rate and result in death.
Begonia: A popular and versatile summer plant, these will cause intense burning and irritation in the mouth if eaten by dogs or cats. Ingestion will also cause excessive drooling, vomiting and possibly make your pet have difficulty swallowing.
Chrysanthemum: Some dogs and cats can be drawn to its unique smell and, in certain cases, digesting it can cause vomiting, depression and a loss of coordination.
Cyclamen: This plant’s root is very toxic to dogs and cats, so if your pet likes to dig and you have these in your garden, look out for intense vomiting. In some cases, fatalities have been known to happen if eaten.

Only certain types are dangerous, including California Ivy, Branching Ivy, Glacier Ivy, Needlepoint Ivy, Sweetheart Ivy and English Ivy. Eating it will cause vomiting, hypersalivation and diarrhea.

Lilies: Highly toxic to cats, even in small quantities, eating these can cause kidney failure. In stark contrast, they are not toxic to dogs.
Tomato Plant: Eating them won’t prove fatal for your pet, but they can give dogs and cats severe stomach pain, diarrhea, drowsiness and slow their heart rate. Dilated pupils are a way to recognise if your pet may have eaten them.
This plant’s bulb has a high amount of toxins in it, so if you have a dog which likes to dig, keep a close eye on it. Convulsions and cardiac abnormalities can occur if this has been ingested.
Although this flower is a spring addition in the garden, its bulb is most the most toxic part and can cause diarrhea, low blood pressure and tremors if digested.

Where can I find more species of poisonous plants for pets?

Obviously, the above list is by no means exhaustive and the number of plants which can prove harmful to your pet depends on which type of animal you have.

But dog owners can refer to a comprehensive directory of poisonous plants for dogs, which has been compiled by the Dogs Trust.

Cat owners may want to refer to a similar inventory which has been put together by International Cat Care, a charity seeking to improve the quality of care for all cats.
