Does were-species run in families? i.e. is the child of two werewolves always (or at least usually) another werewolf, or might it equally well be a were-owl or were-frog or whatever?
If were-species runs in families then were-species would function in society like race, with all the same possibility for discrimination, prejudice, etc., but with the difference that the different were-species have very different physical abilities (and possibly different temperaments) while in animal form. (If some species are actually dangerous and savage while in animal form, does that mean prejudice against them is justified?)
If were-species doesn't run in families, society is likely to be a lot more equal (or at least will be unequal along different lines), but you'd have problems like families of were-mice worrying that their next child might be a were-elephant. They'd have to buy a bigger house and worry about their baby squashing them underfoot.
Also, do people retain human intelligence and control while in animal form, or do they behave like wild animals? If the latter, society could still be civilised if it found a way to deal with its members turning into wild animals sometimes.
