In this adventure of Loula, she overhears her mother say, “I can’t live with that MONSTER anymore!” and Loula immediately assumes she is talking about Loula’s dog, Mister, a Great Dane.  Loula knows Mister is a little too undisciplined most of the time and is determined to change his behavior – and quickly!  She enlists the help of Gilbert, the family chauffeur, and they take Mister through a series of lessons so Mother will allow him to stay.  Villeneuve’s water color and ink illustrations are amusing as they show each attempt and failure of trying to teach Mister some manners.  When they wearily return home, they discover Mother carrying a monstrous Venus Fly Trap out of the house!
