That's pretty interesting; is there a link that lists which strains of E.coli cause illness in dogs and which ones don't?
E Coli is an EXTREMELY common bacteria that is present in almost all animals & humans. The problem is, it comes in many, many different strains, like the the influenza virus.
The vast majority of E coli bacteria cause no illness whatsoever. Certain strains actually help prevent overgrowth of harmful bactieria in the gut. There are a few strains that usually only cause illness in people with weaker immune systems, like children, elderly and people who are immunosuppressed due to chemo or immune diseases. The E Coli 157:H7 that has turned up in beef, lettuce and other items in the food supply is not lethal in the vast majority of cases. Most people who actually do become ill from it will only develop diarrhea. Of the people who develop serious enough symptoms to seek medical attention, about 8% will develop complications that could possibly lead to kidney failure.
From Iowa State University:
Infections in Animals
E. coli 0157:H7 has been found in cattle, sheep, goats, pigs, deer, dogs and poultry. The major reservoir of this organism is cattle; young animals are most likely to shed bacteria in the feces. Fecal shedding may last only weeks to months and can be intermittent.
Currently, there is no published evidence that E coli 0157:H7 causes disease in animals; however, B. Fenwick and colleagues have suggested that this organism may be linked to Idiopathic Cutaneous and Renal Glomerular Vasculopathy of Greyhounds (CRGV). Experimental infection of calves results in no clinical signs. Sheep also appear to carry the organism asymptomatically.

Sorry to get all technical. My sister was an animal science major and her pet peeve is the way people all panic over the mere mention of E Coli. E Coli itself is not harmful, just a select few strains. Those sensationalized TV shows where they say they've found E Coli on keyboards and phones and doorknobs always get her going on a rant!
