Bingo's illness in Bluey, shown in "Bumpy and the Wise Old Wolfhound," isn't explicitly named but heavily hints at celiac disease or a severe gluten intolerance, suggested by gluten-free lunches in other episodes and a doctor checking her breathing, leading to a hospital stay. While some theories point to asthma (due to breathing checks) or other conditions, creators intended it to be relatable and open to interpretation, representing various childhood illnesses or hospital experiences.

Additionally, the way Bingo often mutters and sings to herself (which is shown more prominently in the bonus shorts) can be read as stimming.
