Diarrhea progresses to a mustard colored watery consistency. Do NOT over medicate. Use ONLY Cephalexin, OR Baytril when Cephalexin is not available. Some have used Flagyl, but it works more slowly. Symptoms usually appear 12-48 hours after exposure to the bacteria.
Death occurs because of dehydration.
From the 1st signs of symptoms to death can be as short as 12 hours, or as long as 7 days. Many dogs remain active, alert, hungry, and seemingly healthy during the syndrome. Treat early with 250mg of Cephalexin per 25lbs of body weight. Pups or smaller dogs should be treated with Cephi-drops. One or two treatments, do NOT over medicate since this can throw the bacterial balance off in the other direction.
