Macadamia nuts pose the risk of toxicity in dogs, causing symptoms of muscle weakness of the hind legs, fever, and pain accompanied by tremors, according to the American Society for the Prevention of Cruelty to Animals. Signs of toxicosis typically last for about 48 hours.

Peanuts and pistachios are safe for dogs to eat on an occasional basis, as detailed by the ASPCA. The risk of food poisoning arises when dogs eat an excessive number of nuts. The fat content of nuts increases the chance of pancreatitis, inflammation of the pancreas. Sodium ion toxicosis is also possible when dogs eat heavily salted nuts.
