Not for sure where to post this. Rosco 7mths. old has mucus poop that are sort of runny. I noticed yesterday there was a little bright red blood in it and it really stinks. I have 3 yorkies and he always inhales his food and has gas alot. I figured it was from eating so fast. He seems fine eats good, drinks good and plays. He hasn't been scooting his butt any. What would cause the blood? He is on Natural Balance and for the last 2 weeks I have been mixing royal canin in it, but his diet mostly consists of boiled chicken. They other 2 dogs haven't had any bowel problems.
