In my lifetime (over fifty years) I’ve seen the average human animal change shape in the United States.

The majority of people have been bitten by an old curse. Infected with a beastly savage power that overcomes any compunction they may have had in their less dog-like states to howl in packs and do great harm.
Proudly pissing and shitting all over the place, sniffing each others butts, licking each others balls, stealing each other’s food, invading other’s territories, and terrorizing the weaker resistance and every imaginary perceived threat their deranged leaders sic them on.
Sadly, no silver bullet will solve or put a stop to this mass transformation.

A werewolf never loses his humanity. He is simply more liable to uncontrolled outbursts of his most savage animal form taking over in response to full moons or dog whistles. In this case, he’s liable to see and hear them every day, at a moment’s notice.
There is no constraint of a lunar cycle. Everything is out of balance.
