If possible, it's best to take a photo in a professional pet hospital before treatment. If not, it depends on its fate. It eats nails instead of other foreign objects. Other foreign bodies can be treated by vomiting, but not with pointed nails to avoid scratching the esophagus and stomach. Even if you can be sure that your puppy has eaten the thumbtack, you need to take photos to see the location of the thumbtack, and then do reconstruction surgery or take it out directly with gastroscope forceps. The way he eats steamed bread, sausage and food is not recommended, because what he eats will not necessarily wrap the thumbtacks. Once undigested food pushes the thumbtack into the gastrointestinal tract, especially the intestine, it will be more dangerous, so you'd better not do anything now. Go directly to a professional pet hospital for timely treatment. If you scratch the stomach and cause massive bleeding, it will endanger the dog's life ~! I hope my answer can help you.
