until the dog recovers and runs home.

It may..may take 3-4 such treatments before its burned into his brain
that coming over to your place hurts and is a Bad Thing (tm)

I strongly doubt that the owner would go along with this. I sure as
hell wouldn't.

Dogs respond much better to the carrot than to the stick though some
stick is sometimes necessary. Some breeds are nearly oblivious to
pain, labs being a notable example, but if shown stick and reward in
quick succession they figure that out quickly enough.

Example: say "come" softly, pull on leash. Praise upon arrival.
Repeat. After some of that, take off leash. Say "come" softly. If
dog responds, praise lavishly. The first time he does not respond,
replace leash, say "come" softly and damned near yank his head off --
then praise lavishly upon arrival.

Training a dog by shouting is foolish. Dogs hear just fine, and
quickly learn to ignore all but shouted commands when shouting is the
demonstrated form of emphasis.

Excessive use of pain as a motivator can ruin what might otherwise
have been a good dog. When they get surly and sneaky, they're ruined
and may as well be put down sooner than later.

Some dogs just aren't worth a **** from the gitgo. If they're just
stupid and basically untrainable but someone loves them then they get
kept, but a pet that harms or kills someone else's livestock or pets
is not acceptable. The options are to restrain it, retrain it, or
destroy it.
