Anything ovine has to do with sheep — this is a sheep-specific word. Baa!
Just as canine describes dog-like things and bovine describes cow-like things, ovine is used to describe specifically sheep-like things. A poodle with hair that resembles a sheep is kind of ovine. Someone who shears sheep gives ovine haircuts. A scientist who studies sheep knows more ovine facts than anyone else, except maybe a farmer with a lot of ovine critters on the farm.
