11 Toxic Foods for Dogs: Human Foods Dogs Must Avoid
My dog loves to “help” me cook. He plonks himself by my feet ready to catch any fallen ingredients and offers to clean up the off-cuts!
A symbiotic relationship like this can work well if the household chef knows which human food dogs can eat, because some foods are toxic to dogs. The health risk also applies when feeding table scraps and left-over meals which might contain ingredients that are toxic to dogs (such as onion!)
Furthermore, feeding your dog tidbits can lead to an obese dog before you know it.
TIP: Double check the ingredients list to avoid accidentally giving your pooch food poisonous to dogs.

No! Avocado contains persin, which can cause abdominal upset and symptoms such as vomiting and diarrhea. The skin and seed portion of the avocado fruit are most toxic to dogs but even the flesh on some varieties of avocadoes is toxic to dogs. The leaves and bark of avocado trees are also poisonous and avocado seeds can cause intestinal obstruction if swallowed.
6. Can dogs have coffee, coffee beans, tea and caffeinated drinks?
No! Caffeine containing foods are harmful to dogs. Caffeine can affect the heart, lungs and central nervous system of dogs. Symptoms of intoxication include hyper excitability, vomiting, tremors and convulsions.
7. Can dogs eat nuts?
No! Macadamia nuts can cause vomiting, muscle and joint pain, weakness of hind legs and wobbly gait 6-24 hours after consumption. The toxic effects may persist for 48 hrs.
8. Can dogs eat stone fruit seeds?
No! The seeds of peach, plum, apricot and cherry contain cyanide and if eaten can cause vomiting, rapid and irregular heart rate, heavy breathing and coma. Larger seeds also pose a risk of causing intestinal blockage that requires surgical removal.
9. Can dogs eat bread dough and pizza dough?
No! The high fat, salt and calorie content of pizza makes it an unsuitable human food for dogs. Uncooked pizza dough can rapidly expand in the stomach as the yeast is activated causing painful, potentially life-threatening bloat.
10. Can dogs have Xylitol artificial sweetener?
No! This artificial sweetener (found in sugar free gums, toothpaste, sugar free sweets and sugar free peanut butter) causes insulin release in dogs resulting in a sudden drop in blood sugar levels. Weakness, collapse and seizure can occur within half an hour of consumption. Xylitol has also been linked with liver failure and should be considered very toxic to dogs.
11. Can dogs have alcohol?
No! All forms of alcohol are toxic to dogs. Dogs are much more sensitive to alcohol than humans. Typical signs include vomiting, disorientation and stupor progressing to cardiac arrest.
Why are these foods bad for dogs?
The physiological makeup and digestive capacity of dogs is quite different to that of a human, therefore some of the foods that are healthy for us can be fatally toxic to dogs. The toxic effects of these foods vary greatly between dogs and can be hard to predict.
For example, some dogs happily eat fallen avocados in their backyard on a regular basis while other dogs will experience a serious tummy upset after only a small amount.
The effects of toxic food for dogs are dose dependent – the higher the dose the greater the intoxication. Therefore small dogs are more at risk from food poisonous to dogs than the larger breeds. So, pay attention to what your dog is eating and think twice before giving him your leftovers and dog proof your pantry and fridge.
If your dog eats something that is toxic to dogs, try to determine how much has been eaten and then seek immediate advice from your veterinarian.
