Yes.

Hello, my 3 yr old shih tzu just came home from the animal hospital about 1 hr. ago . They said from test the did it was E-coil most likly. He had been there for 3 days. I took him in after noticed he had been vomiting for about two days. It got really bad really fast, befor I new it he was passing almost pure blood from his rectum. I had never watched a dog so healthy and full of energy become so sick so fast. I did not think he would make it. He is home now and I'm SO GLAD i TOOK HIM WHEN i DID. If i HAD WAITED LONGER HE POST LIKLY WOULD OF DIED. Thank God for Warner Robins Animal Hospital!

No it doesn't. There are many strains of e. coli and most are harmless in dogs and cats. In fact the majority of them have it in their system and nothing bad happens. But there are some strains that are dangerous in pets, especially if it gets in their urinary tract where it doesn't belong ever and can even cause their death. SO that is why you shouldn't let your dog, especially a female dog poop or pee in a dirty area. She could get fecal contamination of her urethra and it can thus get e. coli in it.

"E. coli is a normal inhabitant of the digestive tract of pets, or at least it is found frequently when it does not appear to be the cause of any problem. However, certain strains of E. coli do consistently cause problems and other strains can cause problems when the conditions are right. Cattle sometimes carry the strains of E. coli that are more dangerous and they do sometimes shed these organisms in their feces. So they would be a possible source of an E. coli infection. However, E. coli infections are pretty common in dogs and most of them don't have a source of cow chips, so there are obviously other transmission methods, as well. When E. coli is pathogenic (a disease causing strain) there is a strong tendency for it to be resistant to most antibiotics. Usually the fluoroquinolones (Baytril Rx, Dicural Rx, others) are a good choice, as are trimethoprim-sulfas and amoxicillin-clavulinic acid combinations. An antibiotic sensitivity test may indicate that other antibiotics should work, too. It is important to remember that antibiotics need help in order to kill bacteria. It is very difficult for antibiotics to kill infectious agents without the proper conditions being present in the body for the antibiotic to get to the area of the infection and without the help of the patient's immune system."
