Hypo-allergenic dog food range

Designed to be kind to your dog's stomach


There are many different types of substances that are toxic to dogs.

The most common types of toxins ingested by dogs include medication intended for human consumption, insecticides (e.g. overdose of flea product), rat poison, household cleaners, house as well as garden plants and last but not least food items.

The following list presents the most common food hazards to dogs. Should your dog have ingested any of the listed food items please call your vet's emergency line immediately.


Alcoholic beverages and food products containing alcohol can cause intoxication with symptoms of vomiting, diarrhoea, difficulty breathing, tremors, coma and even death.


Ingestion of avocado can lead to vomiting and diarrhoea. The plant's leaves are the most toxic part but its fruit and seeds can cause symptoms too.


Fish bones, cooked chicken bones as well as bones from other meat sources can obstruct the digestive system resulting in respiratory stress and choking as well as injury to the digestive tract.

Bread Dough

Raw bread dough made with yeast can lead to the expansion of the stomach as the yeast in the dough ‘rises'. The dog may then unsuccessfully attempt to vomit. Further symptoms can include bloated abdomen, ruptured stomach or intestines, weakness and even coma.

Chocolate, coffee, tea and other foods containing caffeine

Can cause digestive symptoms such as vomiting and diarrhoea, and affect the heart and nervous system potentially leading to tremors, seizures and even death.

The principle toxic components of chocolate and cocoa products are the methylxanthines, of which theobromine is the major toxin in chocolate, and caffeine in coffee. Theobromine stays in the dog's body for a relatively long time, around 17 hours. As a consequence of this slow elimination, repeated intake of smaller quantities has an accumulative effect and can still lead to poisoning.

Darker chocolate is more dangerous than milk or white chocolate as it has higher levels of theobromine.

Grapes & Raisins

These fruits can cause kidney failure within 72 hours of ingestion. The toxic substance in grapes and raisins is unknown.


Large amounts of liver fed on a regular basis can cause vitamin A toxicity which affects muscles and bones.

Macadamia Nuts

Macadamia nuts can cause vomiting, muscle weakness, depression, tremors and hyperthermia in dogs. Signs generally disappear without treatment within 12-24 hours after ingestion. The toxic substance in these nuts is unknown.

Milk and Dairy Products

Dogs have a limited ability to digest the milk-sugar lactose, which is found in milk and all dairy products, resulting in digestive problems.


Mushrooms can contain toxins that may affect various body systems in the dog with potentially lethal consequences.

Onions and garlic

Onions and garlic (raw, cooked or in powdered form) can cause gastrointestinal irritation and can also lead to red blood cell damage (resulting in anaemia).

Raw eggs

Raw eggs can contain bacteria such as Salmonella and E. coli that can be harmful to dogs. Raw eggs also contain a substance that decreases the absorption of biotin (a B-vitamin) which can result in skin and coat problems over time.


If ingested in large quantities, salt can cause excessive thirst and urination, vomiting, diarrhoea, depression, tremors, higher than normal body temperature, seizures and even death. Never feed your dog salty foods that are designed for human consumption e.g. crisps, salted nuts or other foods high in salt such as bread or readymade soups.


Just like humans, dogs don't need sugar but they will eat it anyway! Sugar is not nutritious as it doesn't contain any vitamins or minerals and contributes to dental decay, obesity and even diabetes.
