Answer
A case construct can be implemented to handle different scenarios based on the input received, for example: handling the charging mechanism based on the duration of the walk. For instance:
if num_of_dogs > 1:
# Do not charge extra
else:
# Charge accordingly
This logical structure helps in applying the correct rules for charging based on the number of dogs walked.
