A cliché gamer Fic about a dude traveling worlds as a dog

A dude that has no vivid memories about his past gets the gamer system but is reincarnated as a dog as a result of a gacha. (This will be a lot of fun...For me anyway) (Was bored browsing Webnovel and then looked at some random picture of a dog in spartan armor and got an idea for a fic. So don't expect too much from this.) (Chapter length will vary.)
