MB3 97b Pasturing Animals on Shabbos (305:23); Preparing on Shabbos for After Shabbos (306:1)

Giving over an animal to a non-Jew on Shabbos to graze. What if you see a non-Jew using your animal on Shabbos? Telling a non-Jew where to graze your animals on Shabbos.

Preparing on Shabbos for after Shabbos (e.g. going to the edge of the techum) is a problem when it is recognizable why you are doing it.
