Dogs will not necessarily die if they eat butter. If they only eat a little bit and there are no adverse reactions, they will be fine. If they eat more, they may suffer from indigestion, vomiting, diarrhea, etc. In severe cases, they may even cause Gastrointestinal diseases, so it is best not to give butter to dogs. In addition to butter, dogs should not eat chocolate, milk, cakes and other sweets to avoid food poisoning in dogs.
