Can Dogs Eat Macadamia Nuts?
Why it’s a problem
Macadamias cause a distinct syndrome in dogs: weakness in the hind legs, tremors, vomiting and fever, usually within 12 hours. As few as six nuts can affect a small dog, and combining them with chocolate multiplies the danger.
How to serve it safely
Never feed macadamias in any form — plain, roasted, in cookies or in trail mix. Store them where a determined nose cannot find them.
Warning signs to watch for
Hind-leg weakness or wobbliness, muscle tremors, vomiting, fever and lethargy, typically within 3 to 12 hours. Most dogs recover with care, but severe cases need support.
When to call the vet
Call a vet or pet poison hotline as soon as ingestion is known — early decontamination makes recovery smoother.
Common questions
How many macadamia nuts are dangerous?
As few as six nuts have poisoned dogs. There is no known safe amount, so any ingestion warrants a vet call.
My dog ate one nut and looks fine — now what?
Symptoms can take up to 12 hours to appear. Call your vet with the amount and your dog’s weight, and watch closely.
