Are Hostas Poisonous to Dogs?

Many new gardeners are worried about their dogs because animals sometimes eat plants that can be harmful to them. Hosta has been grown in culture for several centuries. During this time, this plant was not considered poisonous. Only now there is information that it can be dangerous for animals.

In certain circumstances, hostas can be poisonous and toxic to dogs. According to the American Society for the Prevention of Cruelty to Animals, hostas are toxic to dogs.

What does biology say?

Scientists say that the leaves and stems of hostas contain saponins, which, when ingested, can cause vomiting.

There are stories on the internet that this plant has poisoned dogs and that the consequences have been hard. However, people are not sure that their pet poisoned eating hosta.

According to studies by biologists, all parts of the plant contain saponin:

  • leaf;
  • stems;
  • flowers;
  • peduncles;
  • roots.


Symptoms of poisoning can be indigestion and as a result of vomiting. More severe consequences are unlikely to be, but we will talk about them below.

If you see something is wrong with your pet, and you find a damaged hosta in the garden. Take your dog to the vet immediately.

At the veterinary clinic, your pet will be provided with all the necessary help. Most likely the clinic will give him a gastric lavage and this problem will be solved.

What can be done to avoid such a situation in the future?

The easiest way is to get a fence around your hosta. It stops the dog from eating hostas. You can also let your dog out for a walk and keep an eye on him.

You know for sure that dogs love to eat grass, and some can taste hosta. But why is this happening? The answer is evident – in their diet of insufficient essential substances (vitamins, trace elements, etc.)

Consult a veterinarian about how to feed a dog to avoid this in the future properly. Weirdly, a healthy, well-nourished dog would eat hostas in your garden.

Dogs in the garden

Most gardeners claim that their dogs were never interested in hostas. Dogs are not such stupid creatures to harm themselves.

My friend has two Rottweilers, and they never touched hostas; the same can said about cats. Many cats passed through my yard, and none of them were trying to eat hosta.

It should be noted that there are known cases where little puppies could swallow some of the hostas leaves. However, even in such cases, everything ended well. They just went through the procedure at the vet, and everything was okay.

The concentration of poison in the hosta is not so significant. For a dog to be in danger, it must eat a considerable number of leaves and stems of hostas. You will probably agree that this is unlikely.

The rhizomes of the hosta contain more saponin than stems. The leaves contain even less of this substance than in other parts of the plant. Saponin has a bad taste and a bad smell. It is doubtful that a dog can eat a dangerous amount of these parts of the hosta.

Vomiting in dogs can be caused even by common grass, which they often like to eat. However, this does not have serious consequences.

Other animals

Many animals eat hostas, such as deer or rabbits. However, nothing happens with them; they do not have vomiting or bloating.

Hydrochloric acid in the stomach of a dog is much higher than in herbivorous animals. All that a dog eats is digested quickly. Therefore, it is unlikely that as a result of eating hosta dog is seriously ill. The exception may be only small puppies.

Hosta is eaten even by people

People also eat hosta. There is a video on YouTube where the hosta is cooked and fried, then eaten. However, what was next with these brave men is unknown. But I don’t think anyone would risk their lives.

I do not convince you to eat hostas. All I am trying to say in this article is that the insignificant amount of leaves that your dog will eat cannot cause serious harm.

Are hosta flowers poisonous to dogs?

Huskies, like other dog breeds, are at risk of getting a stomach upset after eating a hosta. This breed has no immunity from saponin.

Are mini hostas harmful to puppies?

The mini hostas have small leaves, so the amount of saponin in them is scanty. However, puppies are more vulnerable to dangerous substances than adult dogs. So if you grow hostas in the garden and have a puppy, you better not allow it to these plants. Make a fence around the hosta, and try not to leave your pet alone in the garden.
