No support. It's not a bad mechanic, but it is one that really needs to be established from the get-go. Implementing it now would be devastating for the site, as many players (including myself) would simply quit, due to the drastic change of gameplay.
Edit: I also play this game to relax, and dying pets isn't a feature I can chill with. Honestly, I'd be soooooo gutted if any of my wolves died.
