Ok,I know ya'll are going to think I am a little strange here,just coming out of the blue.
I just joined this site yesterday and read this sad story. Am a dog spoiler and amateur dog rescuer,as finances allow!
I will be down in the area starting Aug 2nd...my annual visit.
Just raising a possibility here....to the original poster (Geo)..would you consider letting all of us pay to neuter the dog and get him current on shots and heartworm,then giving him a home with you?
Hope I am not barging in too much here,just an idea to try to help out...
