If the dog eats the ham sausage packaging bag, you need to induce vomiting immediately. If the dog cannot vomit it out, observe the dog’s defecation. If the bag is not expelled after a day, you need to take the dog immediately. Dogs should go to the pet hospital for surgical treatment, because plastic bags in the dog's stomach can easily cause digestive tract obstruction, which can even cause life-threatening injuries. Therefore, timely treatment is required to avoid delaying the condition.
