Foods that are Dangerous or Toxic for Dogs

Whether you are cooking your pooch his favourite meal, or just slipping him or her the odd tasty tit-bit off your plate, it is important to bear in mind that some foodstuffs don't agree with out 4-legged friends. You can help your pal by being aware of these and avoiding them at all costs. This list is not exhaustive, but does give you the most common foods accidentally or inadvertently given to dogs.


This may surprise some people but its is simply down to the high fat content. Avocado can cause stomach problems, vomiting and in severe cases pancreatitis. Persin, which is resident in avocado is toxic to dogs and can also cause heart problems. Additionally the large seed found in the Avocado is a choking hazard or could become caught up in the intestines.


Many of you will know this one already, but it is worth knowing the facts behind why Chocolate is bad for your dog. It is down to the cocoa content and the Theobromide that Chocolate contains. The higher the cocoa content, the more toxic the Chocolate. Should you feed your dog any choccy then the consequences are severe, as before your friend dies he or she will suffer seizures and tremendous pain before they die. It may be yummy and you may think that you want to share this with your pooch - but don't do it!

Beware - bark chipping in your garden can be cocoa bark which is also toxic to dogs, always check with your garden centre before purchasing wood chippings.

Cooked Bones

Never never never give cooked bones to your dog. Cooking softens the bones and these can splinter which could pierce internal organs and membranes. If you want to give your dog a bone... go for a raw meaty one!

Corn on the Cob

Put simply, it's not the corn that is the problem - it's the cob. Dogs can easily choke on such large objects and dogs being dogs will often try to swallow the biggest piece they can!


Be careful with garlic, it seems in small quantities it may be ok, but if you want to be certain - don't use it. Of course the dog medicines or treatments that contain traces of garlic are fine as it is a natural cleanser and a great weapon in the endless battle against fleas.

Grapes and Raisins

Grapes and Raisins can cause a serious amount of damage to a dog's kidneys. Whilst your wide-eyed friend may be looking up at you lovingly whilst you pick through your bunch of grapes, please stop and think before throwing them a few.


If you over feed your dog onions this can cause anaemia. There is no issue flavouring your pals dish with a smattering of onion but serious damage can be accidently caused when for example giving your dog things such a baby meals which often have a high onion content.

Yeast Dough

Whilst it may appear harmless enough, Yeast Dough has a rising agent in it that is not destroyed by heat during the baking process. If you give your dog dough, it could continue to ferment internally and cause wind, pain and possibly rupture internal organs. Small amounts of cooked bread are fine, but by no means the best form of nutrition for your dog.

Plants in the Garden/Park

Finally, it is just worth remembering that plants such as Cala Lilies, Foxgloves, Crocus, Narcissus and Peonies are all toxic to dogs and can cause upset tummies - or maybe even worse. It's not uncommon for a puppy to dig up a bulb or two and have a nibble at them, so always keep your eyes peeled!
