The last year we can read more and more information about how onion is really bad for your dog, so bad the dog can die from it. Ive never heard about this before and though I read all these reports no one I know has ever had a dog that has become ill or died due to onion. And these people have often given their dogs leftovers. I worry about this because we use to give our dog small bits of meatballs or sausages (from the supermarket) but they ALL have onion-aroma or onion-spices in them. So how dangerous is this? Our dog doesnt like treats from the petstore. And I even found that some of the treats from the petstore allso has onion spices! So I get confused. If onion is that dangerous to dogs, wouldn I have heard about this from owners? Someone somewhere should have had a dog that got ill... Do you give your dog treats or leftovers from your dinner even thoug it contains onion?
