We love our dogs and share our hearts and homes with them, but there are some foods that we should not be sharing with them…


Almonds may not necessarily be toxic to dogs, but they can block the oesophagus or even tear the windpipe if not chewed completely.


Avocado plants contain a substance called Persin which is in its leaves, fruit and seed and can cause vomiting and diarrhoea in dogs


Alcohol has a huge impact on dogs even in small doses. The drink not only causes intoxication as it does in humans, but it can lead to sickness, diarrhoea and even central nervous system damage.


This is not just an old wives’ tale. Chocolate and cocoa are products of cacao beans (Theobroma cacao) after they are fermented, roasted, shelled and ground. Chocolate contains two ingredients potentially lethal to dogs – theobromine and caffeine – methylxanthines. There are 1-9 milligrams of theobromine per gram of chocolate, with higher levels in darker chocolate. White chocolate has zero risk of toxicity.

Giving your dog a raw uncooked bone to chew on is great but avoid cooked bones at all cost. These can easily splinter and in large quantities cause constipation or at worst, a perforation of the gut which can be fatal.


Corn is one of the most common ingredients in most dog foods; however, the cob can be hard for a dog to digest and may cause an intestinal blockage, so if you’re sharing some corn, make sure it is off the cob.


Grapes and raisins can cause kidney failure in dogs. Just a small amount can make a dog sick.


As refreshing of a treat as ice cream is, it contains lots of sugar, so it is best not to share with your dog. Also, some dogs have an intolerance to lactose. To avoid the milk altogether, freeze chunks of strawberries, raspberries, apples, and pineapples to give to your dog as a sweet, icy treat.


These are one of the most poisonous foods for dogs. Macadamia nuts, part of the Proteaceae family, can cause vomiting, increased body temperature, inability to walk, and lethargy. Even worse, they can affect the nervous system. Never feed your dog macadamia nuts.


Because pets do not possess significant amounts of lactase (the enzyme that breaks down lactose in milk), milk and other dairy-based products cause them diarrhoea or other digestive upsets in large quantities.

ONION FAMILY – Onions, Garlic, Shallots, Leeks and Chives

The onion family, whether dry, raw or cooked, are particularly toxic to dogs and can cause gastrointestinal irritation and red blood cell damage. Signs of illness are not always immediate and can occur up to a few days later.


The problem with these fruits is the seeds or pits. Seeds from persimmons can cause problems in a dog’s small intestine. They can also block their intestines. This can also happen if a dog eats the pit from a peach or plum.

Peach and plum pits also have cyanide, which is poisonous to people and dogs. People know not to eat them – dogs don’t!!


Sweets, gum, toothpaste, baked goods, and some diet foods are sweetened with xylitol. It can cause your dog’s blood sugar to drop and can also cause liver failure.

NOTE: Dogs love peanut butter but you need to ensure that it does not contain xylitol, a sugar substitute that can be toxic to dogs.
