Here is a list of the 10 most toxic Winter plants for dogs and cats. If you’re wondering which plants are poisonous to dogs, or which plants are poisonous to cats, we hope this list will help you out and put your mind to rest this Christmas season.

The majority of these plants contain poisonous alkaloids (or plant poisons) that can be fatal if ingested.

These plants are extremely popular in the UK due to their striking, beautiful appearance in the winter months, but they are not appropriate for growing where your pets can get hold of them. For safety reasons, they should be kept away from pets and young children.

If the berries or spiked-edge leaves from a holly plant are ingested, they may result in irritation of the mouth, drooling, gastrointestinal upset (such as vomiting), and diarrhoea. They may also cause excessive head-shaking if consumed in large quantities.

Mistletoe 

Mistletoe berries, although vary greatly in type, contain chemicals including polysaccharides, alkaloids, and lectins which are harmful to both dogs and cats. When ingested in small quantities they may cause gastrointestinal irritation such as vomiting and abdominal pain. Consumed in large quantities, they may cause abnormal heart rate, low blood pressure and incoordination.

Poinsettia plants 

These gorgeous Christmas plants are widely known for their bright red and green festive foliage, but the milky white sap from the coloured leaves contains a dangerous chemical. This could cause not only nausea, vomiting, drooling and diarrhoea, but also irritation in the skin, mouth and oesophagus of your pet.

Christmas trees 

If the pine needles from Christmas trees are chewed, the oils released can cause irritations in the mouth as well as stomach upset.

Due to the prickly nature of these needles, it could also be hazardous to the mouth, throat and stomach if ingested.

If you are a household with pets, it may be a safer choice to go with an artificial Christmas tree.
