All [animals] forbidden for the altar render [others] unfit however few there are. [These are the animals forbidden for the altar]: An animal which had sexual relations with [a woman] or [an animal] that had sexual relations [with a man], an animal set aside (muktzeh) [for idolatry], or that had been worshipped (ne’evad) [as an idol]; or that was the fee of a whore, or [a dog's] exchange; or that was kilayim; or terefah; or an animal born through a caesarean section,What is meant by muktzeh? That which has been set aside for idolatrous use. It [the animal itself] is forbidden, but what is upon it, is permitted. And what is meant by ne'evad? That which has been used for idolatry. Both it [the animal itself] and that which is upon it, are forbidden. In both cases the animal may be eaten.

What is meant by the “price of a dog”?If one says to his fellow, here is this lamb instead of [this] dog. And similarly if two partners divided [an estate] and one took ten lambs and the other nine and a dog, all those taken in place of the dog are forbidden [for the altar], but those taken with a dog are valid [for the altar]. An animal that is the fee of a dog and the price of a prostitute are permitted [for the altar], since it says: “[For] both [of these]” (Deuteronomy 23:19): both’ but not four. Their offspring are permitted [for the altar since it says]: “[Both of these]” implying they but not their offspring.

If he gave her [a prostitute] money, it is permitted [for use for the altar.] [But if he gave her] wine, oil, flour and anything similar which is offered on the altar, it is forbidden for the altar. If he gave her dedicated [animals] they are permitted [for the altar]. If he gave her birds [of hullin] they are disqualified. For one might have reasoned [as follows]: if in the case of dedicated animals, where a blemish disqualifies them, [the law] of [the prostitute’s] fee and price [of a dog] does not apply to them, in the case of birds, where a blemish does not disqualify, is it not all the more reason that the law of [the prostitute’s] fee and the price [of a dog] should not apply? Scripture says, “For any vow,” (Deuteronomy 23:19) this includes a bird.

With regard to any animals that are disqualified for the altar, their offspring are permitted for the altar. The offspring of a terefah: Rabbi Eliezer says it may not be offered on the altar. But the sages say it may be offered. Rabbi Hanina ben Antigonus says: a ritually clean animal which nursed from a terefah is disqualified from the altar. Any dedicated animal which became terefah one may not dedicate them, since we may not redeem dedicated [animals] in order to give them to dogs to eat.
