Unfortunately, the answer is no.  Macadamia nuts are toxic to dogs if ingested. If you think your dog may have gotten their paws on some of these nuts, you should contact your veterinarian immediately and begin monitoring them for the clinical signs of macadamia nut toxicity

My Dog Has Eaten Macadamia Nuts, What Do I Do Now? 


As with any health concern, your first step is to call your veterinarian. During this time, be sure to watch out for the clinical signs of macadamia nut poisoning in your pet. 

In the majority of cases, these symptoms include: 


  • The weakening of the rear legs 
  • Diarrhea 
  • Vomiting 
  • High body temperature 
  • Looking sluggish/ depressed 
  • Reduced appetite 
  • Shaking 


While many dogs experience only mild clinical symptoms such as stomach upset or diarrhea, in severe cases dogs may begin to tremble, experience weakness in the rear limbs, or have a fever.  




The first step to treating macadamia nut poisoning is to induce vomiting, activated charcoal may also be administered. In more serious cases, aggressive treatment may be needed. If your dog consumed macadamia nuts in a baked good, bring the ingredient list or recipe with you- as many artificial sweeteners and common mix-ins such as raisins or xylitol can also be poisonous if ingested.
