Wanwan Monogatari: Kanemochi no Inu ni Shite to wa Itta ga, Fenrir ni Shiro to wa Itte Nee!
After being worked quite literally to death, corporate slave Routa Okami's dying wish is to be reborn as the well-loved pet of a rich family. When a compassionate goddess actually grants his wish, Routa commits himself to the lazy, carefree, all-you-can-nap lifestyle of a pampered pup-complete with a beautiful owner and all the delicious food he can eat! But as Routa grows...and grows...and grows...he realizes something is terribly wrong. With his enormous body, razor-sharp teeth, and fierce visage, it's painfully obvious that he was reincarnated not as a dog but as a giant wolf. And not just any wolf-the legendary wolf king Fenrir!
