Most owners are aware that Caffeine is poisonous to dogs. However, not all may realize all of the food products it can be found in.

However large amounts or accidentally swallowing a diet pill can have a detrimental effect.

Coconut oil has become increasingly popular in our daily diets. However coconuts and it’s oil can have a serious affect on your dog.

Certain nuts such as Macadamia nuts are toxic to dogs. Most nuts contain a high amount of fats and oils which can have a bad affect on your dog’s health. So whether they are toxic or not, all are best avoided.

  1. Xylitol

Xylitol is an artificial sweetener found in foods like sugarless gum, sugar-free candy and baked goods. It can also be found in toothpaste, mouthwash, chewable vitamins and cough drops. Ingestion can cause a life-threatening drop in your dog’s blood sugar, as well as liver damage. Symptoms include vomiting, seizures and loss of coordination, which can occur anywhere from a few minutes to several hours after ingestion.

Other Foods to Avoid

Grapes and raisins contain a toxic chemical which is not yet known. They have been seen to cause kidney failure. As it is not certain of the affects they may have on dogs, they are best to be avoided all together. Just as raw or uncooked meats and egg may be harmful to us, they are also harmful to our pets.
