Puppies pick up objects and explore the world with their mouths. Chewing, mouthing, and sometimes swallowing stuff is their way of finding out what’s edible and (ideally) what’s not. Although this behavior stems from a natural instinct that puppies often outgrow—especially with the help of training—it can get them into trouble, even leading to blockages or poisoning.
Eating an inappropriate object can become tempting—even irresistible—when it’s flavored or scented. Common problem items include grease-covered utensils from the kitchen, milky baby bottle nipples, and used tampons or soiled diapers.
