In this video we discuss what to do if your dog ingests part of a tennis ball or other gastrointestinal foreign body (GIFB) (like rocks, corn cobs, peach pits, hair elastics, toys, socks, etc.). We discuss the risks these items pose to dogs, like intestinal obstruction that can require surgery. We discuss when a procedure to the remove the object (like endoscopy or surgery) might be needed. We discuss how to induce vomiting in dogs at home using hydrogen peroxide, and provide other tips to ensure that your pet receives medical care in a timely manner, before it is too late.
