Dogs will not necessarily die if they drink cooking oil. It depends on the specific situation. If the dog only drinks a little and no other abnormal reactions occur, it will be fine. If the dog drinks more, vomiting and diarrhea may occur. In other cases, you need to be sent to the hospital for examination and treatment. Edible oil is high in fat and calories, and a dog’s gastrointestinal tract is very fragile and sensitive, so it is best not to give your dog random amounts of edible oil to avoid adverse reactions.
