Turns out my dog did have colitis and doesn't have cancer...his colitis is pretty much gone. Sunburst animal hospital will be repairing my dogs double hernia, one side at a time, which my vet recommended is the best way to repair perineal hernias (another thing bluepearl didn't advise me on) which will still be about $3500 cheaper than the surgery bluepearl had recommended. And by the way even if I had gotten that tedious $5000 surgery from bluepearl, it still wouldn't have cured my dogs colitis. Very disappointed in bluepearl
