>What is that about she wolves and their depiction that makes them attractive?
Wolves alternate between being sacred and cursed animals in Indo-European culture. Thanks to civilizations like the Romans, she-wolves actually have a reputation as being motherly and nurturing symbolically. Wolves obviously share a lot of behavioral associations with dogs, who always were one of the three sacred animals of Indo-European culture which has survived up to the present day, and it's basically 99% a lot of associations with friendliness, intelligence, nobility, loyalty etc. If you know about wolves scientifically, you also understand material like their pack behaviors* which drive that home. Also one of the few things distinguishing wolves from dogs behaviorally - other than domestication - is that wolves are monogamous, which added to the perception from Roman culture and the dog association with loyalty makes them seem like high quality wives and mothers. But unlike dog girls they also have that association with the primal, savagery, wildness, and freedom that appeals to people. Finally, modern culture has rehabilitated wolves and strongly painted wolves with anthropomorphic behavioral features - (which scientists will complain & deny even as more scientific evidence of their emotional and behavioral complexity comes to life) - that means we closely empathize with them and their behavior as if they were people, as we do with similarly communal and intelligent animals like parrots, dolphins and (again) dogs. That's why stories of wolf children like Mowgli are so common.

TL;DR: Portrayals of anthropomorphized animals almost always use the traits of the original animal, so a she wolf would probably be fit, wild, yet very motherly and protective of her den. They're both strong, tough, independent (warriors?), but also loving and caring, and very loyal.
*People always act like wolf women would be vicious, but they don't really understand how affectionate wolves are with each other. Like how they're one of the few animals that will feed and take care of an injured pPost too long. Click here to view the full text.
