I believe that Couver had a HGE flare up. It was really bad, vomiting, diarrhea and nausea. His poo was bright red and jelly like. I took him to the vet and got him on Sucralfate, Metronodazole (sp) and Cerenia and his symptoms improved. Just recently I'm noticing things are flaring up again and he's vomiting. We are headed to the vet again today
