years ago i had a sal x was la ping and off she went after a charlie , anyway couldnt find her anyway went back the
next nignt switched the lamp on and hey ho she came straight to me ,, fkn sals
...
same with my beddy whippet once she disappeared from home one day. I went to a regular lamping spot 4 miles away turned lamp twice and there was running back to me.
Would be worth walking around with the lamp if dog is used to it at any regular spots in range
