Can dogs eat macadamia nuts?
No, dogs should not eat macadamia nuts, including nuts hidden in cookies or trail mix. Weakness, vomiting, and tremors can follow, and hind-leg weakness can look like a spinal emergency. Call a poison hotline or a clinic the same day.
Portion and preparation
None. Nuts in cookies and trail mix count; there is no safe home portion in ounces (grams), and a smaller pet can be harmed by less than a larger one. Powder, broth, and baked goods count the same as the plain ingredient.
Why this matters chemically
Macadamia nuts contain a toxin that is still not fully identified, and they can cause weakness, vomiting, and tremors in dogs. Cookies and trail mix count; there is no established safe number of nuts in ounces (grams). Keep the package where pets cannot reach it.
What clinical signs can appear?
Signs vary with the amount eaten, the animal's weight in pounds (kilograms), and how much time has passed. The list below is what clinics commonly ask about. It is not a checklist that rules disease in or out for one animal.
- Weakness, especially in the hind legs
- Vomiting
- Tremors
- A high body temperature
What if this was eaten?
Call a poison hotline or clinic the same day. Most dogs recover with care, but weakness can look like a spinal emergency. Remove the nuts; do not give human pain medicine for the weakness; note how many nuts are missing.
Which agencies regulate this advice?
The FDA regulates pet food and animal drugs in the United States.
