It can be extremely tempting to give our furry friends the left over bones from your dinner. Real animal bones, however, can easily splinter into sharp pieces or be swallowed whole, causing punctures and/or blockage in the stomach and intestines. Bones can also get stuck in the mouth or esophagus. Signs that your pet might be having a problem related to ingesting bones include excessive drooling, difficulty swallowing, smacking of lips (indicating nausea), lack of appetite, lethargy, vomiting with or without blood, vomiting immediately after eating, blood in stool, black, tarry stools, absence of stool, and severe abdominal pain. While bones are not necessarily "toxic", they can pose danger to your pet. Depending on the situation, though, there may be steps you can take to help protect your pet following bone ingestion.
