My 14 year old yorkie has been having normal bowel movements for how long I’ve had him. Today, I noticed there was blood in his stool. His stool had a normal consistency for the exception of a streak of blood. This is the first time it has happened and I’m very worried. From my understanding, his only health concern is declining kidney function, because of his age. I need to keep an eye out, other than that, so far he is acting normal.
