'Dogs' in the Bible

"Do not give what is holy to dogs, or throw your pearls in front of pigs, lest they trample them with their feet, and turn around [and] tear you to pieces.

And he answered [and] said, "It is not right to take the children's bread and throw [it] to the dogs!"

So she said, "Yes, Lord, for even the dogs eat the crumbs that fall from their master's table."
