Poisonous Plants For Dogs

Poisonous Plants For Dogs

Which plants are toxic to dogs? How do I know if my dog has been poisoned? These are just two of the most common searches relating to dog poisoning, which unfortunately is all too common, as a result of our four-legged friends coming into contact with certain harmful plants. In this blog we’ll highlight 10 plants commonly found in woodland, parks and gardens across the UK. We’ll also offer helpful tips and guidance on how to keep your canine companions safe during their outdoor adventures.

1. Azaleas/Rhododendrons

Azaleas and Rhododendrons are popular ornamental garden shrubs with vibrant flowers; however they can pose significant health risks to dogs. This family of plants contain something called Grayanotoxins, which are powerful neurotoxins that can be extremely harmful. Ingesting even a small amount of this plant can prove fatal to dogs.

2. Bluebells

Bluebells are a classic feature of British woodlands which add a splash of colour in the spring. Unfortunately this plant contains harmful substances called Glycosides which can cause vomiting, diarrhoea, lethargy and abdominal discomfort for your dog. Whilst the toxicity is quite mild compared to some other plants, ingestion of large quantities can lead to more serious issues.

3. Daffodils

A quintessential sign of springtime, Daffodils are a common feature in both gardens and woodlands. The bulbs in particular are highly toxic to dogs, containing harmful substances that can cause more severe gastrointestinal issues than Bluebells. If your dog were to ingest large amounts, this could potentially cause  tremors, convulsions and even heart problems.

4. Foxgloves

Foxgloves are a stunning wildflower which thrives in woodlands and gardens alike, however this iconic flower is also highly toxic to dogs. The entire plant contains substances that would be extremely harmful if ingested, so it’s important to keep a particularly close eye on your dog if there are Foxgloves around. Symptoms can appear rapidly, so we’d strongly advise you seek immediate veterinary attention if you suspect your dog has ingested it.

5. Hydrangeas

Much like Azaleas and Rhododendrons, Hydrangeas are popular garden plants with large, colorful flower heads. Unfortunately, they are also highly toxic to dogs if consumed. Symptoms of hydrangea poisoning are similar to those detailed earlier, however in severe cases, dogs may experience difficulty breathing, seizures and a significant drop in heart rate.

6. Ivy

Ivy is a common sight in woodlands and gardens, often seen climbing walls and trees. Whilst it may look pretty, it also contains harmful substances that cause gastrointestinal issues if ingested, including diarrhoea and vomiting. It can also be found crawling along the ground, so dogs are at risk of accidental ingestion whilst they’re scavenging along the delicious buffet, otherwise known as the forest floor.

7. Lily of the Valley

Much like the plants already mentioned, ingesting Lily of the Valley is no laughing matter. Often found in shaded woodland areas and gardens, this plant contains something called Cardiac Glycosides, which can cause symptoms similar to those of Foxglove poisoning. Worryingly, even water in which the flowers have been placed can be toxic, so it’s important to be super-vigilant around this plant.

8. Oleander

Another popular ornamental shrub, Oleander contains toxic compounds called Oleandrin and Neriine, which affect the heart’s ability to function properly. Unlike some other species, all parts of the plant, including the leaves, remain toxic even when they have dried-out. As a popular garden shrub, it’s important to ensure any fallen leaves are swept up, away from nosey doggos.

9. Snowdrops

Snowdrops bloom in late winter and early spring, often carpeting woodland floors and gardens, posing the same accidental ingestion risk mentioned earlier, when a dog is scavenging. The delicate flowers contain something called Alkaloids, which can cause symptoms such as nausea, vomiting, diarrhoea and excessive drooling. Whilst less likely to be ingested than the flowers, the bulbs are particularly toxic and can lead to even more severe poisoning if ingested.

10. Wisteria

Wisteria is an extremely pretty climbing plant often seen adorning walls and pergolas in gardens. Whilst its hanging clusters of flowers are beautiful, the seeds and pods are highly toxic to dogs. The seeds contain Lectins and Wisterin, both of which are extremely harmful to dogs. Ingestion can cause gastrointestinal symptoms similar to those detailed earlier and veterinary attention would be advised if you suspect your dog has ingested any part of this plant.

This is by no means an exhaustive list, as other common plants like Crocuses, Poppies & Tulips  are all also harmful to dogs if ingested, as both are Cherry Trees & Yew Trees. We could also talk about flowering Alliums like onions, garlic, shallots, leeks and chives; all of which if ingested can cause anaemia in dogs - the list really does go on and on.

Rather than listing all the potential hazardous plants, we thought we’d pull together some helpful tips and advice to help prevent poisoning happening in the first place.

 

Tips to Prevent Poisoning in Dogs

Identify and Remove Toxic Plants: Familiarise yourself with the plants in your garden and around the areas where you regularly walk your dog. Remove or securely fence off any known toxic plants in your garden, swapping them for dog-safe alternatives. Also consider changing your regular walking routes to avoid any potentially harmful plants.

Supervise Your Dog: This one is much easier said than done, especially if Axel is anything to go by. That said, do try to keep a close eye on your dog when you’re out walking or spending time in the garden. This is especially important if your pooch is predisposed to chewing on plants.

Training: Train your dog to avoid eating plants or digging in garden beds. Simple commands like "leave it" can be effective, especially if good behaviour is then rewarded with treats or praise. This is particularly useful strategy with younger pups who often more inquisitive but also easier to train.

 

What to do if you suspect your dog has been poisoned?

If you suspect your dog has ingested a toxic plant, it is important to seek veterinary advice immediately. The sooner your dog receives treatment, the better their chances of making a full recovery. Even if it’s a false alarm, you’re always better to be safe than sorry. We suggest saving your vet’s contact number in your phone to save valuable time in an emergency situation.

 

Conclusion

Whilst there are potential dangers hidden amongst the natural beauty of the UK’s woodland and even the sanctuary of our own gardens, this shouldn’t be a reason to not enjoy spending time in these areas with your four-legged friend. By familiarising yourself with some of these hazardous plants, you are already significantly reducing the risk to your pet. Armed with the right knowledge and by taking the right precautions, both you and your dog can continue to explore and enjoy the great outdoors safely and confidently.
