Pretty Yet Poisonous Plants For Dogs To Avoid

By Liam Beauchamp-Jones | Pets

Exploring, sniffing and digging - what dog doesn't love spending time in the garden?

With many of us sharing our pooch’s passion for the outdoors, often planting and pruning as soon as the sun shines, we’ve put together a list of plants to avoid when getting your green fingers out. From poisonous plants for dogs to avoid to fatal flowers, here is a list of popular indoor and outdoor plants to keep away from pooches…

Our list of poisonous plants for dogs to avoid:

Aconitum  Asparagus fern  Belladonna 


Also known as wolfsbane or Monkshood, every part of this plant contains a deadly toxin that could be fatal to our furry friends. In fact, it was historically used to kill both wolves and “mad dogs”. If your dog eats the berries of this toxic plant, they could suffer from vomiting and diarrhoea. If your pooch is persistently around this plant, it could also cause severe skin irritation.   Amaryllis Belladonna bulbs are widely known to cause dogs distressing and dangerous symptoms such as vomiting, diarrhoea, lethargy and tremors.
Cyclamen Daffodil bulbs  Lilies   



Although pretty, this flowery plant is highly toxic to your dog. If eaten, the side effects can include excessive salivation, vomiting, and diarrhoea.   Although a popular bloom to brighten up both the home and the garden, daffodils are dangerous when eaten by dogs. While all parts of the daffodil can cause problems, the bulbs are particularly poisonous and can cause symptoms such as vomiting and convulsions. Many animal lovers know that lilies are poisonous to our feline friends, but may not know that there are many varieties that are also dangerous to dogs. When eaten, lilies can cause symptoms such as upset stomachs and even depression. 
Delphinium Foxgloves   Hemlock



 More commonly known as Larkspur, these flowering plants are highly poisonous and pose a great threat to both dogs and humans. While they can cause neuromuscular effects in our pooches, a small amount of the plant can kill a human. They may be a honey bee's best friend, but foxgloves are highly toxic for both people and dogs. If eaten, foxgloves can cause your pooch to suffer severe nausea and vomiting.  Depending on the amount your dog eats, this poisonous herb can cause them to get extremely overexcited and lead to symptoms such as seizures and pain in the abdomen.   
Hyacinths Hydrangeas  Ivy 



If they chew or digest the bulbs of these springtime beauties, dogs are likely to suffer irritation in both their mouth and oesophagus. Common issues include drooling and diarrhoea, while breathing difficulties can also occur when large quantities of bulbs have been consumed.   If your pooch digests this popular plant, they are likely to encounter a seriously upset stomach and possible side effects of depression, high heart rates and temperature, and vomiting.   Fortunately, it is relatively well known that Ivy is poisonous to pooches. Causing serious harm both inside and out, including dermatitis and damage to your dog’s gastrointestinal tract, Ivy should be avoided and never consumed.
Laburnum Lily of the valley  Lupins 

All parts of these glorious golden plants are toxic to your pooch and can cause nausea and vomiting when digested.  They may look pretty and smell sweet, but these plants are highly poisonous to dogs and cause serious harm. When ingested, the plants can cause vomiting, diarrhoea and even seizures.  Although a large amount of this flowering plant would need to be ingested and incidents of Lupine poisoning in pooches seems to be rare, it is known to be toxic to dogs and so should still be avoided.  

Morning Glory





The seeds of this beautiful vine are toxic to dogs, with large quantities causing distressing symptoms such as vomiting and even hallucinations.  This highly toxic tree must be avoided, with every part posing a threat to both dogs and humans. Even taking a drink of still water with an Oleander leaf floating in it can potentially poison your pooch.    From the stems to the blooms, every part of these bushes is toxic to your dog, with only a small amount needed to cause serious issues. While the symptoms vary depending on the size of the dog and the amount eaten, ingestion can be fatal.
Rhubarb leaves Sweet pea plants   Tulips



While the stems are safe to be eaten by your dog, rhubarb leaves can cause serious excessive salivation, lethargy, and even kidney failure.  It may be difficult to detect whether or not your dog is suffering the consequences of eating sweet peas, as the poisoning may take a few days to show up. The severity of the symptoms depends on the amount eaten and range from general weakness to vomiting.  If your pooch decides to dig up and devour the tulip bulbs you have planted in the garden, they may suffer from a range symptoms These include irritation in the mouth and more severe issues such as vomiting and difficulty breathing. 

Umbrella plants


Yew trees 



When chewed or chomped on, the popular houseplant can cause your pooch’s mouth to swell and become seriously agitated.  With two toxic properties present, both the seeds and pods of wisteria can cause several worrying symptoms for dogs.
