One of my father in laws friends dropped there little old dog on our street because he couldn't keep her no more well for the first few days she would come up to me and snap at me if I tried touching her . Even tho she was a ass I still fed and gave her water she now let's me touch her. She sits on my porch and barks at strangers so I got me a little Guard dog now lol. Once I start getting paid I'm going to take her to the vet and let her stay inside
