Dot's dress gets torn when Whyka pulls her out of the quicksand and when they are escaping from the attacking trees yet Dot's dress appears intact throughout the film.
When the Roundies ask Papa Drop what to do with Dot and Whyka, Dot's gag has disappeared but she still cannot talk.
Dot has no verbal communication from any animals from meeting Buster onwards despite previously being able to converse with animals wherever she goes.
When the Roundies capture Dot and Whyka, they wind a rope around Dot's arms. However, when this sequence is shown in long shot, the rope only appears to bind Dot's waist. In the next close-up of Dot, her arms are bound as well.
When Dot is being taken to the 'Prison for Squares' enclosure, she is still tied up. However, when Dot is actually thrown into the enclosure, she is free again.
