Macadamia tetraphylla or
Macadamia intergrifolia trees. The nuts contain sugars (4%) and oils (up to 80%).
Macadamias can be toxic to dogs. Toxicosis can occur in dog after ingestion of commercially available macadamia nuts or macadamia nut-containing cookies or candies. Toxicosis can occur year round, although it is more likely to occur during holiday seasons.
