[Regarding] dough for dogs, if the shepherds eat from it, [it] is obligated in challah, we may make eruvin with it, we may make shitufei [mevo'os] with it, we recite a blessing over it, we participate in a zimun because of it, it may be made on Yom Tov, and a person can fulfill his obligation with it on Pesach.  [But] if the shepherds do not eat from it, it is not obligated in challah, we may not make eruvin with it, we may not make shitufei [mevo'os] with it, we do not recite a blessing over it, we do not participate in a zimun because of it, it may not be made on Yom Tov, and one cannot fulfill his obligation with it on Pesach.  In either case, it contracts tumah of foods.

[Regarding] challah and terumah, one is liable to death for [illegally eating] them and to [a surcharge of] a “fifth,” they are for-bidden to non-Kohanim, they are the property of the Kohen [to whom they are given], they are nullified in [a mixture of] one hundred and one [parts], they require hand-washing and sunset, they may not be taken from [produce which is] tahor on be-half of [produce which is] tamei, [and] only from that which is in [their] proximity and from something “finished.”  One who says, “My entire [crop in the] silo is terumah,” or “My entire dough is challah” has said nothing, unless he leaves over a small amount [as chullin].
