Macadamia nuts bring weakness and tremors to dogs within hours. Oddly, the mechanism behind it is still not pinned down.

Stone-fruit pits and some seeds release cyanide when crushed, and quite apart from that they are a choking and blockage hazard.

What if my dog already ate nuts?
Call your vet or a poison line now with the amount of nuts eaten and your dog's weight, and do not induce vomiting unless a vet tells you to. If nuts was eaten and you then see vomiting, lethargy, tremors or breathing changes, go straight to the nearest emergency clinic.
