How does the childrens picture of Tim Johnson compare with calpurnias description of the dog when she calls mrfinch and misseula may?

In "To Kill a Mockingbird," the children see Tim Johnson as a dangerous, rabid dog that needs to be put down. Calpurnia's description to Atticus and Miss Maudie is more matter-of-fact, emphasizing the imminent danger and the need for action before the dog harms anyone. Both the children and Calpurnia understand the seriousness of the situation but perceive it from slightly different perspectives.
