Chocolate is a sweet treat for humans but a serious danger for dogs!

Chocolate is highly toxic to dogs. As tempting as it may be to share a treat with your dog, even small amounts of chocolate can cause serious health problems. Here is everything you need to know about chocolate toxicity in dogs and how to keep your dog safe.

Why is chocolate toxic to dogs?

Chocolate contains a naturally occurring stimulant called theobromine which belongs to the same family of compounds as caffeine. While humans can metabolise theobromine quickly and efficiently dogs process it much more slowly. This allows toxic levels to build up in their system potentially leading to serious illness.

What happens if a dog eat chocolate?

The risk depends on the type and amount of chocolate consumed. Generally the darker and more bitter the chocolate the higher the theobromine content.

The most dangerous types include:

  • Dark chocolate
  • Baking chocolate
  • Cocoa powder
  • High cocoa content chocolate products

Milk chocolate contains lower levels of theobromine but can still be harmful especially for smaller dogs.

What are the symptoms of chocolate poisoning in dogs?

If your dog has eaten chocolate it is important to watch for signs of poisoning and seek veterinary advice immediately.

Common symptoms of chocolate poisoning in dogs include:

  • Sickness
  • Diarrhoea
  • Excessive panting or rapid breathing
  • Increased heart rate
  • Restlessness or hyperactivity
  • Tremors
  • Seizures
  • In severe cases heart failure or death

Symptoms can appear within a few hours of ingestion and may worsen over time without treatment.

What should I do if my dog eats chocolate?

If you suspect your dog has eaten chocolate, it is important to make a note of the type of chocolate and ingredients for example fruit or nuts from the packaging, along with their weight. Contact your vet as soon as possible and provide as much information as you can. If the vet is happy that only a small amount has been consumed they may advised monitoring for symptoms.

Do not use home remedies or try to make them vomit, this should be done at a vet practice by professionals when needed.

What other human foods are toxic to dogs?

Chocolate may be one of the most well-known foods toxic to dogs, but it’s far from the only one. Many everyday foods found in kitchens across the UK can be dangerous for pets. Chocolates can also contain some of these ingredients.

  • Grapes and Raisins
    Even small amounts of grapes or raisins can cause sudden kidney failure in dogs. The exact toxic substance remains unknown, making these foods particularly unpredictable and dangerous.
  • Onions and Garlic
    Onions, garlic, leeks and chives belong to the allium family and can damage a dog’s red blood cells, potentially leading to anaemia.
  • Xylitol
    Found in many sugar-free sweets, chewing gums, baked goods and peanut butters, xylitol can cause a rapid release of insulin, leading to dangerously low blood sugar levels and potential liver failure.
  • Avocados
    Avocados contain a substance called Persin, which may cause vomiting, diarrhoea and digestive upset in some dogs.
  • Macadamia Nuts
    Macadamia nuts can trigger symptoms including weakness, tremors, lethargy and elevated body temperature.
  • Alcohol and Caffeine
    Both alcohol and caffeine are highly toxic to dogs. Even small quantities can affect the nervous system, heart and liver.
