Inc. The dog's stomach is a sac-like structure designed to store large volumes of food and begin the digestive process. Foreign bodies of the stomach are items found in the puppy stomach that should not be there. Puppies, by nature, love to chew and play with non-food things and may intentionally or accidently swallow these substances. Commonly found stomach foreign bodies include balls, marbles, coins, stones, bottle caps, bones, sticks, clothing, buttons, paper clips, fish hooks, etc. All are capable of being swallowed, but may not exit the stomach and instead become lodged there.
Vomiting is almost always the hallmark sign of stomach foreign bodies.
If the object is large, such as a golf ball, the vomiting may be frequent, even twenty times a day. If, however, the foreign body is small, such as a paper clip, it may not completely block the food passage and the vomiting may be intermittent, perhaps as infrequently as once or twice a week. The puppy may have a decreased or normal appetite. Generally, the larger the foreign body, the less the appetite will be. Complete blockages result in no appetite.
