Dogs explore the world through their mouths, but unfortunately that can mean trouble when the items they swallow include things like clothing, paper, bones and many other items that can wreak havoc on their gastrointestinal system. Cats often will ingest thread, wool, plant materials and small toys, among other things, and are similarly at risk for foreign body obstruction. On this show, Dr. Kathleen Ham will discuss what happens when something gets stuck and causes a foreign body obstruction, what treatments are needed and what pet owners can do to minimize risks associated with this problem, both inside and outside of the household.
