No, dogs should not eat macadamia nuts, not even in small amounts. These nuts are poisonous to dogs and will cause toxicosis.
Toxicosis (toxic poisoning) in dogs often occurs as a result of some foods interfering with the biological processes in the canine's body. The general side effects can be anything from minor vomiting to major ones like a dog's death.
While the cause of the toxins for dogs in many foods (including macadamia nuts) remains a mystery to veterinarians and scientists, the side effects of the toxicosis are clearly defined and can place your dog in significant discomfort and stress, at the very least.

7 Potential Side Effects of Macadamia Nuts for Dogs
The above brief should be a clear indication that you cannot feed macadamia nuts to dogs under no circumstance because macadamia nuts are toxic to dogs.
Below are the seven potential side effects dogs may experience if they ingest macadamia nuts.
1. Gastrointestinal distress.
Large amounts of macadamia nuts for dogs mean large amounts of dietary fat (which could be good in moderate amounts for dogs) and, most importantly, macadamia nut toxin which leads to abdominal pain, vomiting, and loss of appetite in dogs.
2. Canine pancreatitis.
Macadamia nuts are very high in dietary fats, so feeding large amounts to your dog may result in canine pancreatitis because dogs are not designed to process that much of it.
Pancreatitis is an inflammation of the pancreas, which causes the pancreas to malfunction.
Pancreatitis causes significant pain and discomfort for your dog. The dog may lose his appetite, his stomach may be tender and swollen, and he may frequently vomit.
3. Lethargy in dogs.
The serotonin levels in macadamia nuts are suspected of having some role in their toxicity to dogs. The more macadamia nuts a dog eats, the more the serotonin levels increase in their body, resulting in mild to severe forms of lethargy.
4. Hyperthermia and fever in dogs.
The toxins in macadamia nuts can result in hyperthermia, a condition where a dog’s temperature becomes dangerously high. Dogs with hyperthermia experience high levels of stress and their other important body systems will suffer. As a result, dogs may experience gastrointestinal, neurologic, respiratory, musculoskeletal, and renal problems.
Dogs may also develop a fever at this stage of the toxicosis.
5. Ataxia (hind limb paresis) and tremors.
Giving macadamia nuts to dogs can cause ataxia and tremors. Ataxia presents as a loss of balance and uncoordinated movement, often manifesting itself in hind end weakness.
Dogs with ataxia may stagger around, fall down, or pace in circles. Tremors and dizziness can also accompany ataxia, further complicating the dog's overall health condition.
6. Joint stiffness and pain.
Dogs may experience a painful inflammation of the joints after eating even small amounts of macadamia nuts, resulting in stiffness and discomfort.
7. Pale mucous membranes.
Normal coloration for a dog’s gums should a healthy pink color. Dogs who have macadamia nut toxicosis may have pale mucous membranes which are indicative of a low blood cell count and/or shock.
