Fortnite Chapter 2 Season 6 has added raptors. They seem really troublesome to tame and unlikely to provide much benefit, if prior experiences with tame-able non-player beasts are at all indicative of their non-performance.
Getting eaten by wild wolves in the middle of a fight with a real player is a joy. Beyond that instance, I have not found the animals to be a meaningful or even distracting addition to the game: being the last one alive on the island.
