Scooter had coccidia when I first got him too, the vet said the breeder probably had no idea because it is "ignited" by stress - like travelling or going to a new owner etc. So she wouldn't have seen any signs at home.
It's very important your breeder knows also, because all of her dogs probably have it and she needs to do some serious cleaning and meds to get rid of it before another litter becomes infected also.
Good luck and I hope the first round of meds work for you!
