what a shame....not responsible for the kennel to put dogs together without checking if in season,intact,sick or dog aggressive.hope all turns out ok.
contact the breeder as soon as possible to see if ok to just go ahead and spay...preferably once the bleeding part stops,they bleed less in surgery.
but whatever you do, avoid the mis mate shot aka abortion shot...that can have serious side effects including pyometra and bone marrow suppression.
good luck!
