Common plants and other items in your yard, home, and countryside that are poisonous to your dog

Dogs love to be good at sniffing and sniffing around in the undergrowth, and they often seem like they’ll chew on absolutely anything.

But there can be hidden and unexpected dangers everywhere, from your back garden to the wild nature that could injure or even kill your pets.

In gardens and in the country there are a number of plants that are considered poisonous to dogs. They range from common garden plants like primroses and tulips to plants like foxgloves and horse chestnuts that can be found on dog walking trails across the country.

Most plants cause mild side effects and would need to be eaten in large quantities to cause harm, but there are some more dangerous plants dog owners should watch out for and here are some of the most common…


Azaleas are flowering shrubs known for their famed beauty. They come in a variety of colors, most commonly pink and red, but the flower is also highly toxic. It contains andromedotoxins in its leaves and nectar that can cause nausea, vomiting, depression, coma, and difficulty breathing in dogs. Consumed in large enough quantities, the garden plant can be deadly.


Foxglove is another well-known flower that is beautiful but deadly. The well-known purple-pink plant grows in large quantities in the British countryside between June and September, but can cause several health problems if consumed. Seizures, abnormal heart rhythms, and death are possible outcomes for dogs that ingest the plant. Breeding French Bulldogs and Pugs should be banned according to a charity – you can read more about it here.


Daffodils, also known as daffodils, bloom predominantly in spring and are often found in gardens and parks. Daffodil bulbs contain toxic calcium oxalate crystals that can cause dermatitis, nausea, vomiting, and diarrhea. Swallowing the bulbs can be fatal, so dog owners should exercise caution when digging up their daffodils.


Wisteria is a flowering plant in the legume family found in many gardens in the UK. The plant contains lectin and wisteria glycosides, both of which are toxic to dogs. When consumed, common side effects include nausea, repeated vomiting, and stomach pain. Wisteria seed pods are even more toxic than the plant and can cause severe diarrhea, dehydration, and collapse.


Canola is a bright yellow flower found in fields and farmland. The plant is used to make cooking oil and animal feed. There have been many misconceptions about the effects of canola on dogs. Posts that have surfaced on social media have claimed that the flower can cause blindness and damage to the nervous system. However, the reality is that most dogs remain asymptomatic after exposure to canola. In rare cases, the plant can cause gastrointestinal distress and skin reactions resembling burns, but these cases are extremely infrequent.


Mistletoe growing in the garden is unlikely to be reached by your dog, but it can be problematic if used for Christmas decorations around the house. Consumption of mistletoe berries can upset the gastrointestinal tract and cause dermatitis. If eaten by a puppy, even a few berries can be deadly.


Apricot kernels contain cyanide and can be fatal to dogs.


Apples, like apricots, contain cyanide in their seeds. They can lead to death in the worst of circumstances.


Yew leaves and berries can cause dizziness, dry mouth, abdominal cramps, drooling, and vomiting. Yew can be fatal to dogs.

castor bean

All parts of the castor plant used to make castor oil are deadly to dogs and humans, and even consuming small amounts can be deadly.


Eating parts of the oleander can cause heart problems, severe digestive problems, dermatitis, and sometimes death in dogs.


Tulips can be harmful if eaten in large quantities. They can cause skin allergies and itchy rashes.


Primrose leaves can cause stomach upset and even dermatitis.

horse chestnuts

Horse chestnut tree poisoning usually occurs within one to six hours of ingestion. Every part of the plant is toxic to dogs and can cause seizures, muscle tremors and spasms.

grape vines

Small bunches that develop on the vine still have enough tartaric acid to make dogs sick. When ingested in large amounts, they can cause nausea and vomiting.

aloe vera

Often found indoors, aloe vera can also be problematic for dogs. Common side effects are mild but not uncommon, including diarrhea and upset stomach.


Onions when eaten by dogs can cause anemia. They should not be fed to dogs in any form.


Stems, leaves, and unripe green fruits of tomatoes can cause gastronomic problems.

wax tree

Poisonous. It can cause severe blistering dermatitis if it comes in contact with your dog’s skin.


The foliage and acorns of oak affect the kidneys when consumed. Symptoms are delayed and appear after several days.
