Of course, He doesn't! That's ridiculous. Yet, there are actually some (especially those in the same crowd that sees "paganism" under every rock), who are out there, trying to tell people that God hates dogs.
In their attempts to show why, they use such passages as Revelation 22:15 ... which, on the surface, DO seem to put dogs in the same category as wickedness.
But this is because the allegory is taken out of context.
Let’s look at the actual Hebrew meanings of passages such as Matthew 7: 6 and Revelation 22:15, which will help to clarify:
Matthew 7: 6. You should not hang earrings on dogs and you should not place your pearls before pigs that they should not trample them by their feet and they overtake and wound you. (AENT)
Revelation 22:15. Without (will be) dogs and sorcerers, and whoremongers and manslayers and idolaters, and everyone that loves and does falsehood. (AENT)
The word “tithlon” (hang) was misunderstood as “talon” (to give); “qudesha” (earrings) was misunderstood as qudsha (holy). The picture of hanging earrings on dogs dovetails with giving pearls to pigs, and the symbolism of the two animal groups could not be clearer, as dogs represent apostate Jews, and the pigs, apostate Gentiles who are ignorant of YHWH and His Torah.
Either way, the lesson here is do not give what is precious to those who will not appreciate the value. It's got nothing, whatsoever, to do with God "hating dogs"....
Be very careful about whom you choose to believe, as there are many opinionated people "out there" making wild accusations on things about which they know absolutely nothing.
And yes, they ARE ready, willing and able to take their "truth" and trample you to death with it, tearing you to pieces verbally ... all while believing themselves to be doing God's Work.
