That is because Sandeep Reddy Vanga, the director of the film, is from the Telugu industry himself. But it looks like the platform has pulled down the Telugu dub due to some reason.
Users have been complaining on social media that Animal is not available to watch on Netflix with the Telugu audio. It might be some glitch because there is no reason that Netflix would put the movie down.
Of course it has had its share of controversy, and it is possible that the OTT version will have some cuts in the movie. But that does not mean it will be put down entirely.
Animal is very popular throughout the country and the view count increases every day. Even if it is a glitch, Netflix should take care of it immediately.
It really is concerning if people do not get to watch the movie in the language that the director of the film speaks in.
