I know this should be in the general section but lots more people look at the food section and I am really afraid that it could be really bad. Buster was just outside acting kind of weird and a little slow and he pooped and the first one had just a little red on top of it then five minutes later he pooped again and it was completely red. It didnt look like blood because it was a brighter red than blood and really runny. I am pretty sure he hasnt gotten into anything because he has been with me non stop for the past couple days. How concerned should I be and what should i do?
