Every once in a while when we play tug-o-war Jersey's gums will start to bleed. Mike was playing with her today and it happened again. I checked her mouth and it appears to be just around the middle teeth...just past her canines but not the big molars in the back. Those teeth aren't very large and it looks like it may just be the fabric rubbing up against the gum line that's making her bleed. I'm not too worried as it doesn't happen too often, but I'll definitely be asking my vet about it the next time we go. Has anyone else had this happen?
