The Dangers of Karaka Berries for Pets

Posted by Dr. Feargus McConnell, BVSc on 23rd Jan 2025

As summer sets in across New Zealand, the beautiful Karaka tree (Corynocarpus laevigatus) comes into fruit. While its vibrant orange berries may look harmless, they pose a serious risk to our furry friends. If you’re a dog owner, it’s essential to know about the dangers of Karaka berries, how to spot the signs of poisoning, and what to do if your dog ingests one.

Why Are Karaka Berries Dangerous?

Karaka berries contain a toxin called Karakin, which can be extremely harmful to dogs. Even a small amount can cause severe symptoms, so early intervention is critical. These berries typically ripen and fall between January and March, meaning they’re a seasonal hazard in our parks, bush walks, and even some backyards.

Signs Your Dog May Have Eaten a Karaka Berry

Keep a close eye on your dog during walks in areas with Karaka trees. If they eat a berry, you might notice symptoms such as:

  • Vomiting
  • Diarrhoea
  • Tremors or seizures
  • Confusion or disorientation
  • Weakness or collapse
  • Difficulty breathing

Symptoms can appear within an hour or take up to 48 hours to show, so it’s crucial to act quickly if you suspect ingestion. In severe cases, Karaka berries can be fatal.

What to Do If Your Dog Eats a Karaka Berry

  1. Remove your dog from the area to prevent further ingestion.
  2. Contact your vet immediately. Karaka berry poisoning requires urgent medical attention, so call ahead to let them know you’re coming.
  3. Avoid inducing vomiting unless instructed by your vet, as this can sometimes make the situation worse.
  4. Bring a sample of the berry or a photo to help your vet identify the toxin.

Preventing Karaka Berry Poisoning

  • Learn to identify Karaka trees and avoid walking your dog near them during fruiting season.
  • ​​​​​​​Supervise your dog closely on walks, especially if they have a tendency to scavenge.
  • Use a basket muzzle for dogs who are prone to eating things off the ground.
  • Remove any Karaka trees or berries from your property if you have pets.

Keeping Our Pets Safe

The best way to protect your dog from Karaka berries is awareness and avoidance. Familiarise yourself with the tree and its fruit, and stay vigilant during the summer months. If you’re ever in doubt, it’s always better to err on the side of caution and consult your vet. By staying informed, we can all enjoy a safe and happy summer with our pets.
