question on long range dogs getting lost

I have a dog just like that but raised her from a pup n trained. She will def find pigs and dnt know when to stop. Lot of my hunts I say oh this will be short hunt(3-4 hrs). Shoot I allways speak to soon they turn in to all nighters but constantly getting on pigs. But with my experience with her she will come back eventually. Heck was hunting down around the brazos river on the prison land and my gps n radio tracker collars both died on her as she got on pigs. I had to leave her there and never thought I'd getter back. Week later I got a call from a lady that had her at her house I was very grateful.
