"(Yawn!) I'd better get up and chase the mice out for the day!"
Storyline
Jerry and Tuffy believe they've found an ally to keep Tom at bay in the form of a large mean hound dog, but they soon realize that the angry hound immediately turns nice and docile whenever a pat on the head or a kind word starts his tail wagging. The cat and mice wage a wagging-war, with Tom patting and complimenting the dog to start his tail wagging, and Jerry and Tuffy doing anything they can to stop it.
Story Notes
This could very easily have been the plot for a classic-era Tom and Jerry theatrical short, with no Tuffy and the dog being the only character that speaks (probably voiced by an uncredited Daws Butler, and with composer Scott Bradley's music score suddenly shifting comedically back and forth from "loud-and-angry" to "soft-and-placid"). Harvey Eisenberg's lively pencil art gives the story the feel of such a fully-animated short.
