Hosta is a perennial herbaceous plant in the Agavaceae family. There are over 40 different species of these hardy plants in the genus of the same name. Hostas are native to Eastern Asia and can grow in a variety of conditions.

Hostas are low-growing plants with ribbed or striped leaves at the base and flowers at the very tip of the stalks. These stalks emerge from the leaves, and the flowers are in clusters in white or a blue-purple mix. Hostas are frequently used in landscaping or as potted plants in homes.

Saponins found in Hostas are toxic to dogs and other small animals. Saponins cause nausea and diarrhea, which are common symptoms of hosta poisoning. If you have dogs, you should avoid planting hostas on your property and keeping these potted plants in your home.

Hosta poisoning in dogs occurs when dogs consume the hosta plant, which contains saponins that are toxic to dogs and harmful when ingested or in contact with the skin.

When a dog chews on any part of the plant, it shows signs of hosta poisoning. Hosta poisoning in dogs can manifest as the following symptoms:

  •       Pain in the abdomen
  •       Vomiting
  •       Diarrhea
  •       Bloating
  •       Appetite loss
  •       Intestine twisting
  •       Distress

Toxic saponins found in the Hosta plant cause poisoning in dogs. Saponin poisoning can occur due to the following factors:

  •       As saponins enter the digestive tract, they foam up.
  •       The foam causes paralysis of the digestive tract.
  •       The intestines will twist and load due to the paralyzed digestive tract.
  •       Contact with saponins on the skin can cause irritation and pain.

Saponins are found in a variety of plants, and many natural soap makers rely on these plants for their hobbies and business. Saponin-containing plants include the following:

  •       The Christmas rose
  •       Fern of asparagus
  •       Trees of the horse chestnut
  •       The cow cockles
  •       Daisies
  •       Soapwort
  •       Broomweed
  •       Cockle of corn

If your dog consumes a hosta plant, he may experience abdominal pain and other symptoms soon after. It’s critical that you take him to the vet so that he can be closely monitored and treated for saponin toxicity.

When you call the veterinarian, the veterinarian may instruct you to induce vomiting on your own by giving him the veterinarian-recommended solution. Bring a sample of the plant as well as the dog’s vomit. When you arrive at the veterinarian’s office, he will inquire about how much he ate, how long it has been since he consumed the hosta, and how much he may have consumed.

A complete physical examination will be performed by the veterinarian, which may include blood testing, a biochemistry profile, and a urinalysis. The veterinarian will also examine your dog’s mouth and skin for signs of irritation from the milky, slightly sticky sap. If necessary, the veterinarian will thoroughly rinse your dog to help rid him of the irritant.

Testing will assist your veterinarian in determining the type of toxicity that your dog has. It will reveal any chemical imbalances in your dog’s system as well as whether or not the organs are functioning properly.

After the veterinarian has determined that saponin poisoning has occurred, he will immediately begin treatment. Treatment options include:

#1. Creating vomiting

If your dog has not vomited, the veterinarian may administer emesis medication to help rid your dog of the saponins. This will most likely be followed by the administration of activated charcoal to aid in the absorption of the toxins and prevent them from entering your dog’s system further.

#2. Decontamination

The veterinarian will immediately wash and rinse your dog with a gentle cleanser and water to help remove any sap that has gotten on his face, eyes, coat, or skin. To get rid of the toxic irritant, the doctor may need to repeatedly flush his mouth and eyes with water.

#3. Fluids injected intravenously

Giving your dog IV fluids is an excellent way to prevent dehydration, restore system imbalances, maintain proper electrolyte levels, and encourage kidney function and urination. If your dog has an allergic reaction to the saponins, an antihistamine may be combined with the fluids.

#4. Monitoring

The signs will most likely fade within a few days, if not longer, but the veterinarian will want to continue effective and consistent monitoring of his kidneys and other systems. The veterinarian may keep the dog overnight to continue monitoring him and check his blood work for signs of progression.

After you have returned your companion from the veterinary hospital, it is critical that you keep a close eye on him and note any new symptoms that may appear. Keep him resting and avoid rough play or prolonged outdoor time.

Your veterinarian may also recommend a new diet for your dog, at least temporarily, until he has fully recovered and his gastrointestinal tract is ready to accept his regular food again. The veterinarian may recommend a bland diet with a list of foods he wants your dog to eat, or prescription dog food that is very gentle on his system.

Your veterinarian will discuss any needs that you need to provide for your dog at home, as well as what to look out for in terms of new behaviors. If your dog is still taking medication, such as an antihistamine, make sure to give it to him properly and on time every day.

In terms of follow-up visits, your veterinarian will notify you when he needs to see your dog again to ensure that he is recovering well from hosta poisoning. Remove any hostas from your property, or make certain that you can watch your dog every time he goes outside to ensure that he does not consume any more of this poisonous plant.
