This tweet from Devo's owner, WilcoFour, does raise some obvious questions: Namely, how did lasagna end up in a cemetery bush in the first place? But despite having never found more, Devo keeps looking.
“He knows it’s there somewhere. He knows he is right and I’m wrong when I drag him away. That’s why he will be back there again next time. To eventually prove himself right,” WilcoFour told The Dodo. “I think his optimism is a beautiful thing!”
But Devo isn't the only hopeful pup. While dogs often conveniently forget certain commands, or how to go about those less pleasant daily routines, they can be persistent to a fault when they think they might gain something tasty. (Apparently, the word "dogged" came about for a reason).
