Hi. I have a cocker spaniel who is 9 weeks old. We have had him for a week. After being here a day he did a loose poo with a clear gell and red fluid around it. I assume it is blood. He doesn't always have blood type liquid around his poos. They are better when he does a more solid poo, but the sloppier the poo, the more red/clear gel we get. Any suggestions on what this might be?
