5 yrs old is going to be extremely challenging, the dog has so many bad habits. I guess it could be done though, he just wont be a GREAT hunter, might be killed, might not. As far as eating raw meat goes, I have never fed a dog raw meat, but wolves eat raw, and stray dogs probably eat roadkill, so I guess it wouldnt kill him.
the dog is merely a lure.
Does he know about this?

He may not WANT to hunt if knew this...
