The plants that are poisonous to dogs

How innocent looking plants can harm your dogs

 

You may be surprised to learn that many of the flowers that bloom in your garden may be poisonous to your fluffy friend. Some are extremely poisonous and could be fatal if consumed, while others could cause a little bit of an upset tummy. Nevertheless, whether deadly in their nature, or only capable of a mild reaction, it's better to be safe than sorry and know exactly what is safe for your dog.

 There is a long list of house and garden plants that are poisonous to dogs, and often cats too. Some plants are only poisonous in their bulb form, while others may cause more of a reaction when they flower.

Many of us who own a dog will also have plenty of garden space for them to roam around in. With that comes space for plants, flowers, trees and weeds. It's surprising just how many common plants can be toxic, and even describe themselves as being so on the back of their seed packets.

A mature dog generally learns to be quite cautious and choosy about what they eat, and so with age, they will usually lose any interest that they have in sniffing and chewing amongst your shrubs. However, young puppies are often a lot more inquisitive, and may find it hard to refrain from chomping on what they shouldn’t.

Some breeds will also be more curious than others. If you have a hound on your hands, or another eager eater such as a Labrador, then you may notice that they will eat anything they can get their hands, well paws, on.

 

Watch out for that grass!

Then there are the grass munching dogs, who will graze and graze on grass every single day. These dogs also run the risk of taking in other plants during consumption, and so it is better to be safe than sorry, and oust them from your dog’s reach.

The best and most sensible thing to do with your garden when you have a dog is to use prevention where possible, and then apply common sense. Try to avoid planting seeds of things you know to be poisonous to your dog, and then make yourself aware of both the appearances of other common, poisonous plants, and learn what to do should you find yourself in a potentially dangerous situation with plant poisoning.

Acorns

Dogs are most likely to get acorn poisoning in the autumn when they fall from the trees. If your dog has a chomp on some fallen acorns, they may experience vomiting, diarrhoea which may contain blood, and they may feel very sleepy. If your dog is a frequent acorn eater, it may lead to kidney or liver problems, or cause a blockage.

 

Fungi

We live amongst thousands of variants of fungi here in the UK. With all fungi species varying in toxicity, attractiveness, and appearance. It is unfortunately often very difficult to distinguish between what ones are edible and which are extremely dangerous - both to dogs and humans. If you see your dog eat wild or unknown fungi, take them to the vets immediately, and take along a sample or photograph of the fungi.

 

Festive Plants

Holly is generally considered to be low in levels of poisonousness, but the spiked leaves can cause internal damage and pain. Holly berries can also be a cause of an upset tummy. If your pooch eats some ivy, they may experience a sore tummy, and potentially a skin reaction if they have prolonged contact with the plant. While the toxicity levels of poinsettia are often exaggerated, consumption can cause vomiting and excessive salivation. We may think mistletoe is romantic, but nobody likes an unsettled tummy on Christmas, so avoid puppy kisses under this festive shrub.

If you're instructed to take your dog to the vets, make sure to take a sample of what they have consumed, and notes of where they were and what they were doing. It will be helpful for your vet if you can let them know when your dog was exposed to the poison, how they have been acting, how much they consumed (if you know), and what you think they may have eaten.
