When something reminds you of a wolf, you can describe it as lupine. German shepherds are much more lupine than pugs are.
A lupine person, animal, or thing shares some of the characteristics of a wolf. You might describe your brother's sharp-toothed smile as slightly lupine, worry about your sister's lupine habit of howling at the full moon, or admire your dog's noble lupine profile. The adjective lupine comes from the French word of the same name, with Latin roots: lupinus, "of the wolf," from lupus, "wolf."
