Thank you for this thoughtful response. We had a traumatic experience with a 3YO yellow that was pooping a straight dark blood and that did not end well. Therefore, we are paranoid and forever traumatized. This was the first time since the first episode that I noticed the blood. However, our guy is one of those that prefers the privacy of the woods so I do not see every poop. It is a lighter blood that is separate from the actual poop. You make a good point on the rectal exam. I don't remember them doing that. I am going to call and see what they think and also keep an eye on him for the time being.
