Are there any wolf games that are like howrse and what is it?

Well on Wolfquest you can hunt Horses but playing as Horses - no such thing. On game maker you can make a 2D Platform remake (see link below) but I can't really help you on this one.

EDIT: You don't hunt horses... You hunt elk. There is one game I know of but you are not a horse you are a deer. Its very interesting, you don't have goals or anything but you do have a human like face and a deer body. Its called the endless forest and it is ONLY compatible with PC's which sucks :( cuz its really good. Its is a MMORPG type game and has a lot of fun things inside like magic and random events. But horse wise I have not found one. You can try looking in the game console world if you have a wii or DS or other there might be one.

Edit: Well you can actually download endless forest if you get wineskin, which is like a cover that helps u download PC games to mac games, thats how i got Feral Hearts, where u can be a feline like tigers or lions even hyenas. So u can google wineskin and download it. Theres also a new game called Arokai with more animals like bears and deers.hope this helps :)
