A boy named Junior, who mistreats his dog Elvis, is scolded by his mother. His mother sends him to his room and tells him to think about treating his dog nicer. Junior then decides to take a nap and dreams about being a dog adopted by a loving little girl, who doesn't know that dogs aren't supposed to be washed in a washing machine, bandaged from head-to-toe after being beaten up by a scrappier, smaller dog, or toothbrushed with shaving cream, which gets him caught by animal control who mistake him for a rabid dog. After Junior realizes how horrible being a dog is, he awakes from his dream in shock. Now sensitive to his own dog's feelings, Junior vows to be nicer to him. After Junior leaves the scene, a plot twist is revealed when Elvis tells to the audience that he's not a real dog, but he's also a boy who's stuck in a dream of being a dog, just like Junior himself.
A similar scene from "A Kiddies Kitty" in this cartoon where Junior as a dog is thrown into a washing machine by a little girl and comes out of the machine as a big ball of fur is cut when aired on The WB, due to animal abuse.
According to the Toonheads episode "Ralph Phillips", the little boy bully who owns Spike the dog in one scene from this cartoon is a caricature of Chuck Jones, the creator of the Ralph Phillips character. This may be the reason why this cartoon was paired with Ralph Phillips' two cartoons in the Toonheads episode, "Ralph Phillips".

The department store where Junior (in his dog form) runs into is called Stacy's, which is based on the Macy's department stores. In the Merrie Melodies short, "The Mouse on 57th Street", there's a department store called Lacy's.
