Karaka trees (Corynocarpus laevigatus) are a native treasure in New Zealand, providing essential food for wildlife and playing a vital role in the ecosystem. However, their bright orange berries pose a serious risk to our canine companions.
Why Are Karaka Berries Dangerous for Dogs?
Karaka berries contain karakin, a highly toxic compound (Neurotoxin) that can cause severe poisoning in dogs if ingested. The berries drop from the tree between late summer and early autumn, creating a hazard for dogs who may be tempted to eat them.
Signs of Karaka Berry Poisoning
If a dog eats Karaka berries, symptoms can appear within 30 minutes or take up to 48 hours to develop. These include:
Weakness or wobbly movement
Vomiting and diarrhoea
Confusion or seizures
Paralysis
Without urgent veterinary treatment, Karaka poisoning can be fatal.
How to Keep Your Dog Safe
Identify Karaka trees: If you walk your dog in coastal or bush areas, learn to recognise Karaka trees and their distinctive berries.
Avoid known risk areas: Steer clear of spots where berries have fallen, especially during fruiting season.
Use a lead: When walking in areas with Karaka trees, keep your dog on a lead to prevent scavenging.
Teach a strong 'Leave It' cue: Training your dog to ignore tempting but dangerous items can be life-saving.
Check your property: If you have a Karaka tree in your garden, regularly clear fallen berries and consider fencing the area off.
Karaka Trees: A Vital Part of New Zealand's Ecosystem
While dangerous to dogs, Karaka trees play an essential role in supporting native wildlife. Their berries are a crucial food source for native birds like kererū, tūī, and weka. The trees also provide habitat and help stabilise coastal and forest environments.
What to Do If Your Dog Eats Karaka Berries
If you suspect your dog has ingested Karaka berries, seek immediate veterinary attention. Do not wait for symptoms to appear - early intervention can be life-saving.
