So um, why can't she put her in the back yard until she finds her a home? Just curious. And why not let the lady who emailed you adopt her? The neighbor obviously hasn't found her a home at this point. And yes, they should take her to the pound if necessary, she is a loose unowned dog on the neighbors property, who is unspayed. I don't want to see her put down so I hope she gets a home, but they are just doing their job, your neighbor isn't being responsible about it, sorry.
