I need to do a lot of research for my newest project involving anthropomorphic wolves and foxes. I want them to act relatively animal-like with regards to territorialism, pack structure, mating, etc. One of the questions I've come across is how exactly wolves and foxes behave when mating -- i.e. do breeding rights go exclusively to the group leaders/alphas, do they regularly engage in polygamy or incest and the like, etc.? I recall reading that male foxes will have incest with their daughters, but I can't remember the source for that tidbit.
