Just as a wolf resembles a dog, a flatterer looks like a friend.
Literal
Wolf [subject-が] dog [to-に] resembling like, flatterer [topic-は] friend like appears.
~ように ('just as') draws a comparison. おべっか使い ('flatterer, sycophant') is a colorful compound: おべっか (flattery) + 使い (user). The sentence draws a moral parallel between wolf-dog resemblance and the deception of flattery.
