hi everybody has enyone had this problem and if so does anyone know the cure, and where does it come from

E coli information.

thanks for that jean but i have just mated 4 other people's dogs and they are all in whelp, but i have just mated 2 of my own bitches and no pups, i gave them antibiotics which covers all streptococi bacterial infections so i was wandering if my bitches have ecoli or could they have something else,

Do they have diarrhoea? E coli can only be diagnosed by examining stool samples under the microscope.

Noticed from an old post that you've had this problem previously.  Are these bitches from the same lines?
