It's Karaka tree berry time again so we thought we'd remind you of the dangers of this plant to your dog, along with some others you should be aware of.
January to April is high season for Karaka berries. These orange berries, fall from their trees and can be fatal if ingested by dogs. Symptoms of Karaka berry poisoning include weakness, vomiting, confusion, and convulsions. These symptoms may not present until hours or even days after ingestion.
Many of us have been aware of the poisonous effects of foxgloves on humans, but we also need to be wary of this beautiful flower around our dogs.Foxglove contains poisons that affect the heart. These poisons are called cardiac glycoside toxins, and they interfere directly with electrolyte balance within the heart muscle.Note, that all parts of the foxglove plant are poisonous.
Many lily varieties also contain the same type of toxin, so please be aware around these plants.
If your dog likes to cool off with a refreshing swim, beware of blue green algae, which can cause vomiting, diarrhoea, jaundice, seizures and even death. An alternative is to take your dog to the beach but bear in mind to check your local council's website for beach safety information. If the water at the beach isn't safe for you, then it's not safe for your dog.
Other plants that are toxic for dogs include Black nightshade, Deathcap mushroom, Daffodils (especially the bulbs), Ivy (some species), Rhubarb, Aloe Vera, Onions and garlic, Baby’s Breath, Bird of Paradise, Tomato Plant (green fruit, stems and leaves), Wandering Jew, and Barley Grass seeds.
