My 4 year old "winnie" dog/Jack Russell is passing a gel like stool. Yesterday we noticed him dragging his hind parts across the floor and leaving a red stain. We watched him thinking it was a "fisher" or some sort of tear in his back side. Well today it has changed to this gel like stool and I don't know what to do or think. Yesterday he was acting fine. Running and playing like normal. Late last night and now he is lying around. I have to watch him closely because the red "goo" is sometimes still there.
Can someone please advise me about this?
Thank you
