Macadamia nuts are rarely fatal, but they can have long-lasting effects on your pet's health. They've been known to affect the muscular systems of dogs, causing swollen limbs, weakness, panting and tremors. Macadamia nuts have also been known to damage nervous and digestive systems. So far, dogs are the only animals in which macadamia nuts have been shown to be an issue, but they remain a choking hazard for any small animal.

The cob is difficult to digest, meaning it will get lodged in your pet's small intestine and cause intestinal obstruction - which is potentially fatal without surgery.

This one probably goes without saying, but never ever, ever, ever feed your dog chocolate! Though the caffeine is certainly detrimental to a dog's health, chocolate also contains toxins known as theobromine which cause vomiting, diarrhea and fatal damage to your dog's heart and nervous system. The darker the chocolate, the more likely it is to cause severe, if not fatal, issues. Just don't do it!
