Plants That are Toxic to Dogs

Many garden plants are poisonous to dogs. Some of our most beautiful and useful plants are deadly to our pets (cats as well as dogs), so it pays to be aware of the risks and keep your pets well away from them. Puppies to the age of about 18 months are better off kept fenced away from most garden areas. This protects both the dog and the garden. Many indoor plants are also poisonous to dogs – so all indoor plants should be moved up out of Fido’s reach.

Brunfelsia, (Yesterday, Today & Tomorrow) is perhaps the most dangerous plant for dogs (especially puppies). It is the common small flowering shrub with the violet, lilac and white flowers, all on the same plant. This is a poisonous plant for dogs, and if they eat the plant, especially the fruit which comes after flowering, they may die. You should consider removing or at least fencing off this plant.

Stephanotis. (Madagascar jasmine) There have been quite a
 reports of people who have lost their dogs as a
 result of them eating the seed pods of stephanotis.

• oleander (Nerium oleander)& yellow oleander (Thevetia   peruviana)
• many bulbs (including daffodils,onions and snowdrops)
• toadstools
• potato plants and green potatoes  
• tomato plants

These toxic plants can cause serious damage to the:
• liver
• kidney
• heart
• central nervous system.


Plants that are known to cause skin irritations

Wandering jew (Tradescantia albiflora) is very common in gardens especially in moist, shady areas. It is a horrible weed that will grow in near total shade and almost can’t be killed. Dogs love lying on it in cool areas, as it is comfy and cooling. Sadly, it causes an allergic skin reaction in almost all dogs. A rash and later, ugly callused areas of skin form on the ‘elbows’, groin, stomach, under the chin and any other area that the dog rests on. It is hard to kill pull it out and it miraculously regrows.

Another bad skin irritant plant is Roheo, sometimes known as Moses in the Cradle, it is related to wandering jew and is also highly irritant. Our Zoe just has to put her face near it and she breaks out.

In cases of poisoning, the veterinary profession is superb
at treating dogs, but is not as thorough with plant
identification as it could be, take along a sample of the plant for identification.

Animals that have ingested a toxic plant require urgent veterinary treatment, treatment is supportive, as there a few antidotes available for plant toxicities.

Try to train your pets not to chew any garden or indoor plants.
