Spent friday evening at the vet with Kona. Apparently he is suffering from colitis. The only thing I can think of that might of brought it on was the introduction of raw to his diet I was beginning. I was doing it in very small amounts. Has anyone had any incidences of this when switching to raw? I have decided to hold off on the switch until I research. Also was told by vet that Kona has an enlarged prostrate. He said this is common in intact males. Anyone have any experience with that also?
