    Poisonous Plants And Dogs - What To Watch Out For

    I heard through your dog chat page that daffodils are poisonous! I’ve got a little puppy and wasn’t aware of this. Luckily, he didn’t chew any while they were in bloom a few weeks ago. But what other plants must I watch out for around the garden which could be dangerous? – Katie

    Oh yes, Katie, you must be careful of daffodils around your dog. Luckily, the bulbs are the most poisonous part, however they can still become ill through eating the flower or by drinking the water from a vase. Signs of poisoning includes vomiting, stomach upset and salivation, but can escalate to dogs appearing sleepy, wobbly on their legs, or collapsing. In more serious cases it can result in changes to heart rate, body temperature and blood pressure, and even lead to a seizure.

    Here are some other plants to be cautious about:



    The toxins are particularly irritating to the mouth and digestive system, resulting in drooling, vomiting and diarrhoea.



    Most crocus species will only cause a mild stomach upset, but the Autumn Crocus can cause kidney and liver problems too.

    Tomato Plant


    The actual tomatoes are fine, as long as they are ripe, but the leaves and stems for the plant can cause stomach pain, weakness, difficulty breathing and a slow heart rate.



    These are highly toxic, particularly in small dogs, and can cause serious stomach upsets.

    Deadly Nightshade


    As the name suggests, this can be deadly. The plant, especially the berries, affect the nervous system.



    This plant contains toxic cardiac glycosides, which means that it can cause heart disturbances. In addition to this, it can lead to nausea, diarrhoea and kidney problems.

    Poison Hemlock


    Even a small amount of this plant can cause a dog to die. It is also toxic to humans and livestock. It leads to respiratory paralysis.

    By no means it this an exhaustive list, and there are many other plants out there, both around the house and out on walks, so the best advice is not to leave anything to chance. If you think your dog has ingested any plant, then contact your vet immediately before symptoms appear.
