Found dog/Dog needs a home

My friend found (what seems to be) a dumped dog who she has named Marcy. She's kept Marcy for a bit over a week now while both trying to find her owner and trying to find someone to take her but can't continue to do so. My friend will have to take her to the animal shelter soon and unfortunately there are limited spots. The shelter said they'll have to euthanize another dog in order to take her in. Marcy was found near Park Duvall area. If anyone is interested in giving Marcy a home, please let me know.
