Dogs sense the world differently from humans in terms of sight, hearing, taste, smell and touch (more on this will be covered in dog training tips).  So it may come as no surprise that they also process foods differently than humans.

Alcohol contains ethanol, which can cause lethargy, weakness and low body temperature in your dog and lead to rapid damage to your dog’s respiratory and central nervous system.

Avocado contains persin, which can damage heart muscles and cause respiratory distress.

Too much caffeine lead to death.

Chocolate contains theobromide, a chemical that can damage a dog’s lungs, heart, kidneys and nervous system. Baking chocolate is the most toxic to dogs.

Sugarless candy and gum contain xylitol, which can stimulate a dog’s pancreas to secrete insulin and lead to low blood sugar and severe liver damage.

Garlic & onions, as well as close members of the onion family like shallots and scallions, contain compounds that can damage red blood cells and cause anemia. Be sure not to feed your pet any concentrated forms of these things as well (e.g., dehydrated onions, onion soup mix or garlic powder) as this can cause toxicosis in dogs.

Grapes/raisins & currants can damage kidneys and cause kidney failure. It is unknown why these fruits are so toxic to dogs, but it can only take 4-5 grapes/raisins/currants for your dog to become very ill.

Fat trimmings & bones can cause digestive upset. Cooked bones can splinter when a dog eats them and puncture the digestive tract.

Macadamia nuts are not usually fatal, but even a handful of these nuts can lead to vomiting, muscle & joint pain, swelling and lethargy.

Milk & dairy products can cause diarrhea and digestive upset because dogs are prone to lactose intolerance, so remember that sometimes there can be too much of a good thing!

Raw yeast/bread dough, like alcohol, contains ethanol, and can have the same effects. Be sure to seek immediate medical attention if your dog has consumed ethanol.

Other foods that should be avoided in large quantities are raw eggs (due to the possibility of salmonella) and raw meat & fish, which can cause food poisoning.

We hope that this can help you keep your dog safe, happy and healthy!
