My dog had emergency surgery on Tuesday to remove an obstruction from his small intestines. He was discharged on Friday afternoon. He had 2 small bowel movements that afternoon – both were diarrhea or very soft. He is eating a bland diet of chicken and rice. He is not vomiting, but he has not had a bowel movement in almost 48 hours. He is also taking tramadol. His surgeon is not in today to answer if this is normal. Should he be taken into the emergency vet?
