Expert shares fatal list of toxic foods that dogs should never eat

Many pet owners are more than happy to share their dinner with their dogs – but while many human foods are perfectly safe and even healthy for your pooch to eat, others can be dangerous and make them feel very ill.

Canine experts at Battersea Cats and Dogs Home have shared a list of toxic foods that your pup should always avoid eating, including avocado, chocolate and grapes. The charity advises: “If consumed, even small amounts of these items can be fatal so always act immediately and take your dog to the vets.”

  1. Avocado
    While you may love avocadoes in your salads or sandwiches, they are actually poisonous to your pooch.
    Avocado plants contain a substance called persin, which is in its leaves, fruit and seed, and can cause vomiting and diarrhoea in dogs.
  1. Artificial sweetener (Xylitol)
    Many of our favourite sweet treats and fizzy drinks are laced with an artificial sweetener called xylitol, which causes an insulin release in our bodies.
    It isn’t dangerous to humans but if your dog digests sweetened foods, they can go into hypoglycaemia, which is linked to liver failure and blood clotting disorders.
    You should always check the labels of human foods, such a peanut butter, before feeding them as a treat.
  1. Corn on the cob
    Many dogs enjoy eating sweetcorn and the corn itself is digested by dogs, but you should never feed them the cob.
    Corn on the cob can be fatal if consumed by your dog, as the cob can cause a blockage in their intestine.
  1. Cooked bones
    It may surprise a few people, but you should always avoid giving your dog cooked bones.
    Raw and uncooked bones are great to chew on, but cooked bones can easily splinter and cause constipation or at worst, perforate the gut which can be fatal.
  1. Chocolate
    As much as we love eating chocolate, it is another poisonous food for dogs.
    Chocolate contains a stimulant called theobromine which is toxic to canines and can cause kidney failure.
    Dark chocolate has the highest content of this and should be especially avoided.
  1. Macadamia nuts
    Macadamia nuts are one of the top human foods you shouldn’t give your dog.
    They contain a toxin that can affect your dog’s muscles and nervous system, resulting in weakness, swollen limbs and panting.
  1. Grapes and raisins
    Both grapes and raisins may cause severe liver damage and kidney failure to dogs.
    The active ingredient which causes the toxin is unknown, but they should be avoided at all costs.
    You should always check the ingredients of human foods, such as cakes, biscuits and cereals, to be sure before feeding your pooch.
  1. Alcohol
    Dogs cannot safely consume alcohol – even small doses can have a huge impact on their health.
    Alcohol can lead to sickness, diarrhoea and in the worst case, central nervous system damage.
  1. Onions, garlic and chives
    Whether raw or cooked, dried or powdered, the onion family is particularly toxic to dogs and can cause gastrointestinal irritation and red blood cell damage.
    Signs of illness are not always noticeable immediately and can occur up to a few days later.
