<p>My dog ate a glass Christmas tree apple ornament. I had to take her in to vet on christmas eve. Vet was more concerned about the hook getting passed than he was about the glass. She passed blood in the stool and it was scary. So x rays showed where the problems were. The vet recommened high fiber diet for a few weeks to help the hook piece pass. I had to check stools for a whole week for more blood and for the ornaments hook. Dogs are different than cats but I thought I would pass along the info on watching the stools for a while.</p>
