Mrs. Canfield is a character in Diary of a Wimpy Kid: Dog Days. She appears when Greg imitates Gramma in order to give her a reference. She later reappears when Greg begins his lawn-mowing business. However, there were dog poop piles around her lawn, and he steered around them. As a result, she becomes upset that her lawn wasn't fully mowed and sends Greg home with out paying, which infuriates him and later causes him to think that she is bad-mouthing him.
