If you’re a dog owner with a green thumb, you might be wondering if geraniums are safe for your pup. While not all types of geraniums are poisonous to dogs, it’s crucial to identify the toxic varieties to protect your canine companion from potential health issues like vomiting and diarrhea. Let’s explore more about geraniums and dogs.

What Is Geranium Poisoning?

geraniums plantsGeranium poisoning is a type of toxicity caused by eating scented geraniums.

Avoid confusing this species of geranium for the nontoxic one called the cranesbill geranium. Although both come from the same family called Geraniaceae, they are different genera of plants.

Scented geraniums are categorized under the Pelargonium genus, while cranesbill geraniums belong to the Geranium genus.

You can tell them apart by looking at the shape of their flowers. Geranium plants sport 5 identical petals. In comparison, Pelagorium plants possess asymmetrical flowers, with the upper petals larger than the lower ones.

The Pelargonium genus has more than 200 species of plants and over 1,000 cultivars. They are all considered potentially toxic to dogs.

Causes of Geranium Poisoning in Dogs

3 pots of geraniumsScented geraniums have 2 primary compounds that can cause poisoning in dogs:

  • Geraniol
    It is a kind of terpene alcohol, which is a stomach and skin irritant. Inhaling this chemical may result in toxicity.
  • Linalool
    Similar to geraniol, linalool is a terpene alcohol that can cause stomach discomfort and skin rashes. It is also known to cause abnormalities in heart function.

Know that essential oils derived from scented geraniums are highly toxic to dogs because they contain heavy concentrations of geraniol and linalool.

Furthermore, the scented geranium essential oil is commonly used as an ingredient in many human products, from cosmetics to food. They can be found in perfumes, insect repellents, shampoos, jams, and jellies.

We often come across the question: “Are geranium leaves poisonous to dogs? Yes, Geranium leaves of the Pelargonium genus are poisonous to dogs, so make sure that your furry pal does not ingest or come into contact with them.

How Toxic Are Geraniums to Dogs?

Scented geraniums are mildly toxic to dogs, according to the Pet Poison Helpline. These plants only produce small quantities of poisonous chemicals. Hence, they rarely cause life-threatening side effects unless ingested in large amounts.

However, keep in mind that this is not the case for scented geranium essential oil. It is extremely potent because it contains high levels of volatile oils. Exposure to a small dose of essential oil can be poisonous enough to result in a fatality.

Symptoms of Geranium Poisoning in Dogs

When swallowed, the geraniol and linalool in scented geraniums interact with the stomach acids, leading to gastric issues such as:

  • Nausea
  • Vomiting
  • Diarrhea
  • Loss of appetite

Depression, slow heart rate, and low blood pressure may occur if your dog ingested the plant in large amounts. Skin contact causes itchy and painful rashes as well as reddened skin.

Deadly aspiration may take place if dogs accidentally breathed in their vomit when experiencing geranium poisoning.

What to Do If a Dog Eats Geranium?

Contact the ASPCA Animal Poison Control and inform them about your dog’s interaction with geranium.

To gauge the severity of the situation, they will typically inquire about:

  • Your dog’s size and weight
  • The species of geranium eaten
  • The parts and amount consumed
  • The time of ingestion
  • Visible toxicity symptoms

Stomach upset due to mild geranium poisoning often does not warrant a trip to the vet. The gastric issues tend to go away within a day or two.

In most cases, dog owners are advised to temporarily switch their dogs to a bland diet so their digestive tract can rest.

Skin rashes caused by the plant disappear within a few days too. Just make sure to wash the affected area with a dog-safe shampoo and warm water. It will rinse the toxic chemicals off of his fur and skin.

If your dog displays severe symptoms of geranium poisoning, he should be sent to the vet immediately. Do the same if he has ingested geranium essential oil.

Diagnosis of Geranium Poisoning in Dogs

The vet will also carry out other tests to provide an accurate diagnosis such as:

  • Echocardiography (ECHO): It helps determine the stability of your furry pal’s electrical and muscular heart functions.
  • Endoscopy: It provides a view of your dog’s gastric tract to check for undigested plant matter.
  • Fecal and urine examination: It checks for ingested plant particles and other potential poisoning causes.

Treatment of Geranium Poisoning in Dogs

Treatment will start by administering an emetic to induce vomiting in poisoned dogs. This process helps in removing any plant matter from their stomachs.

Activated charcoal will also be given to keep the harmful toxins of the scented geranium from getting absorbed into the bloodstream.

IV fluid therapy is done afterward to prevent dehydration and decontaminate the body from toxins at the same time.

The vet will prescribe medication according to your dog’s toxicity symptoms. Anti-emetics drugs are used to alleviate vomiting, anti-acids for stomach upset, and topical ointments with anti-inflammatories for skin dermatitis.

Prognosis of Geranium Poisoning in Dogs

Most cases of geranium poisoning in dogs are not life-threatening. Most dogs can make a full recovery after a few days of hospitalization.

However, the prognosis is less positive for severe toxicity caused by exposure to geranium essential oil or ingesting excessive quantities of the plant.
