That's exactly why I had a hard time with the movie. It was weird. I got into this zone during one stretch earlier this year where I watched several movies that all had dogs in them. And in every single one, without exception, the dog died. After I watched The Lobster that was the final straw. Now if a dog makes an appearance I pause the movie and google whether or not the dog lives. If it doesn't, I switch movies, lol.
Now I'm going to contradict myself and say, if you get a chance and you can take difficult scenes involving animals, watch White God
