Can Dogs Eat Macadamia Nuts?

No—this is one food that’s completely off the menu for dogs. 

Even plain macadamia nuts can cause problems, and foods that contain them—like cookies, candies, or trail mix—can add even more risk. It’s not just about being rich or salty—these nuts can actually make dogs sick. 

If you want to offer a safe, crunchy dog treat, try these favorites: 

Macadamia nuts are one of those foods where the risk isn’t subtle—they can make dogs feel pretty awful, pretty quickly. 

• They’re toxic: Even a small amount can lead to real poisoning symptoms. 
• Weakness and wobbliness: Dogs may seem unsteady, shaky, or reluctant to stand or walk. 
• Vomiting and discomfort: Upset stomach is common, and some dogs seem sore or sensitive to touch. 
• Extra-risky add-ins: Chocolate, raisins, and sweet coatings can stack additional dangers on top. 
• High fat: On top of everything else, these nuts are rich enough to upset digestion. 

If your dog got into macadamia nuts, don’t wait it out—call your veterinarian for guidance. 

In the meantime, watch closely for: 

• Vomiting 
• Weakness or trouble standing 
• Wobbliness or unsteady walking 
• Tremors or shaking 
• Fever or feeling warm to the touch 
• Lethargy or low energy 
• Diarrhea 

Call your veterinarian right away if: 

• Your dog ate any amount of macadamia nuts 
• The nuts were in chocolate, cookies, or candy 
• Your dog seems weak, wobbly, or “off” 
• Your dog is very small or has other health concerns 

If your dog starts vomiting or has diarrhea, dehydration can follow—watch for signs like increased panting, a dry nose, or low energy. 

Treatment depends on how recently your dog ate the nuts and how they’re doing, but the goal is to keep them comfortable and stable while symptoms pass. 

• Early care: If caught quickly, your vet may recommend making your dog vomit to remove the nuts. 
• Supportive care: Many dogs need decontamination (with activated charcoal), fluids, anti-nausea medication, and monitoring. 
• Mixed exposures: If chocolate or raisins are involved, treatment may be more intensive. 
• Hospitalization: Some dogs need close observation until the weakness and tremors improve. 

This one comes down to staying a step ahead—these nuts should always be kept out of reach. 

• Keep nut bowls and baking ingredients off counters and tables. 
• Be mindful of cookies, candies, and trail mixes. 
• Don’t leave snack bags in purses or backpacks your dog can access. 
• Let guests know not to share human snacks. 
• Double-check holiday desserts and gift tins. 

Yes. Macadamia nuts are toxic to dogs and should always be treated as a real poisoning concern. 

Dogs may develop vomiting, weakness, tremors, fever, lethargy, trouble walking, and diarrhea. 

There is no safe amount to test at home. Dogs can get sick from relatively small amounts, so any exposure is worth a call to your vet. 

Yes. Chocolate macadamia products are even more dangerous because they combine multiple risks.
