Poisonous plants to dogs

Share this article with a friend

We all love spicing up our homes with plants, but we need to be aware of plants that could cause harmful effects to our pets. Here are 7 poisonous plants to dogs that could pose serious health risks.


Poisonous plant #1: Nightshade

Even though this plant looks great in your garden, it can cause serious health problems to your dog. Nightshade is a type of weed and contains atropine, a commonly used drug in medicine. Atropine causes dilated pupils, uncoordinated movement, fever and seizures. The toxin is found in highest amounts in the berries of the plant but if you suspect your dog has eaten any part of the plant, take them to the vet immediately.

Poisonous plant #2: Azalea

Azaleas come in many different colours and look great in the garden, but they are quite toxic to our furry friends. We need to be careful they do not nibble on them. The toxin is found in the leaves and nectar of the plant.  If your dog eats this plant, some common signs you see include drooling, diarrhoea, muscle weakness, trouble breathing and collapse.
