My loxes run free in the wild, to reproduce they have to be close so I use the saddle to bring them closer, then I feed them and pet them and it works somehow because I already have a nice herd. I tamed them also without any fences. As I know, if tamed animals have too little space for each of them they stop reproducing. When I don't have too much meat for wolves, I lock them together, so there's no new ones to feed until I come back from hunting or fishing xD
