Chimpanzees for instance have enormous canine teeth, but the males have them and not the females, so the idea here is that normally a big canine tooth, a sexually dimorphic canine tooth is probably related to inter-male conflict, rather than to killing and, and whether, how that affects your er what you say about the spacing I'm not sure, but certainly it would be a safe  erm  generalization to say normally big canines are an aspect of sexual dimorphism and in mammals are very common.
