Are Geranium Flowers and Leaves Poisonous / Toxic to Dogs?

Yes, geranium flowers are toxic to dogs. This applies to all species of geranium flowers including those that fall under the pelargonium genus.

What happens if a dog eats geraniums?

Geranium poisoning can be dangerous to dogs. The severity of the reaction will depend on a number of factors such as the number of geraniums the dog ate, the part of the plant the dog ate, and the dog’s weight. Common symptoms of geranium poisoning include vomiting, loss of appetite, and lethargy. Topical exposure to geranium may also lead to skin irritations.

The toxins that make geraniums unsafe for dogs are geraniol and linalool. Both toxins can cause serious irritations in the dog’s body, especially if a dog was exposed to a strong concentration. Severe symptoms like seizures and heart palpitations can’t be ruled out for dogs that eat too many geraniums.

How toxic is geranium essential oil to dogs?

Pet owners need to be careful with using essential oils in the presence of a dog. Geranium oil is one of the more toxic essential oils to dogs. As it is already in liquid form, it’s much easier for the toxins to get absorbed by the dog’s body. The geranium oil can be dangerous even when it is diluted and diffused into the air.

What to do if your dog ate geraniums

Call the vet. Symptoms of geranium poisoning may not always kick in immediately. Some dogs may act normal at first before showing a sudden onset of worrying symptoms like vomiting. Be prepared to answer questions like how the dog got exposed to geranium and how long it has been since the dog ate the geranium flowers or leaves.

    My puppy chewed on a geranium leaf. She had the whole leaf in her mouth and I was able to remove it in the nick of time. I see one or two holes in the leaf. Should I call the vet?
