i truly dont think so. feel like it's a missed opportunity. the werewolf pack is the closest we've gotten and it misses the mark by about half.

Okay so I know that we're probably talking about Sims 4 here, but I've found a face preset for snouts for Sims 2 on modthesims (search for "lupine" on the site). It's not perfect for my standards but you can easily adjust it if you have the extra sliders mod for Body Shop. The skins you can get from genensims along with accessories like ears and tails.
Unfortunately, that's about it. To my knowledge, the accessories persist even while in shower or swimming, but I haven't tested if the skins get inherited to offsprings or not.
Edit: one issue is that you can't easily get rid of the human ears without editing the skin. I just give my sims long hair to sorta hide them.
