Help save my dog Marley

Hi everyone, my dog Marley just got diagnosed with Pyrometra which is a infection in the Uterus and is serious and life threatening. We were told that we would need to have her in surgery by Wednesday or it will be fatal to her. Right now me or my family don't really have the money to do the surgery and would be devastated to lose our dog Marley. anything will be appreciated, thank you so much <33333
