Your summary doesn't really match up. But this is a werewolf story about a vet finding his soulmate. Maybe this is it. http://www.mangago.zone/read-manga/ookami_wo_karu_housoku/
Thank you babe, but not this one
This one is new, if I'm not mistaken it's only one or two chapter ┗( T﹏T )┛
It's ok I find it already, its MOONLIGHT HOWLING
I'm looking for manga, I forgot the title, it's about a vet who dreamed about having sex with a guy, and one day he saw a guy went to the clinic where he work and he accidentally saw the guy turn into Wolf, something like that
