As the weather warms up for summer, it’s natural that we’ll all be spending more time outdoors. And this includes our furry family members. But being out in the fresh air does mean more access to plants and berries that could harm your dog. So, what about irises? Are irises toxic to dogs? And what should you do if your dog has eaten some?

What Are Irises?

Irises are elegant, tall, brightly colored flowers that bloom in spring and summer. They are perennial plants that pop up every year, bringing color to any garden. Depending on their features, Iris can be called flag irises or bearded irises. They grow from bulbs and usually have tall stems with elongated leaves. The flowers can vary in color but are often yellow, blue, or white combinations. The bulbs can be planted from late fall to early spring for blooms the same year.

Are Irises Toxic To Dogs?

Plants from the iris family (Iridaceae) are toxic to dogs and are listed in the ASPCA list of toxic plants. This is because they contain pentacyclic terpenoids, including zeorin, missourin, and missouriensin. The highest concentration of these toxic compounds is found within the rhizomes or bulbs of the iris plant. 

What Are The Symptoms Of Iris Poisoning In Dogs?

If your dog has eaten part of an iris plant and has iris poisoning, you might notice symptoms like vomiting and diarrhea. Often, the gastrointestinal signs are pretty mild. However, in severe cases, diarrhea may contain blood. Your dog might also drool or dribble excessively. They might also cause your dog to be lethargic and stop eating their food. As well as a stomach upset, iris poisoning can also cause a skin rash or skin irritation.

What Should You Do If Your Dog Has Eaten Irises?

If you know that your dog has eaten irises, you should contact your veterinarian right away. Your veterinarian might decide to give an injection to make your dog sick if they’ve eaten the irises within an hour or two, especially if they’ve eaten the bulbs or rhizomes. If it has been longer, they might choose to monitor your canine companion closely and give symptomatic treatment to control any nausea, vomiting, or diarrhea.

If your dog is acting unwell and you have irises in your garden or know that they have been somewhere with irises, iris poisoning could be a possibility. Therefore, it’s worth seeking veterinary advice and letting them know that your dog may have eaten irises.
