Dutchess heartworm treatment

Hey everybody,  Dutchess has heartworms and the treatment is very expensive.  Anna Urbin and her rescue Save a soul sanctuary is handling all this. So please dig deep this little girl was starved for over a month while trying to nurse 4 puppies in a flea infested filthy pen. So if you can spare anything I'd greatly appreciate it and so does this little sweetheart.  Thanks.
