Bob’s beloved “wonderfully mushy” blanket symbolizes Bob’s very coddled and comfortable life. In contrast to Boss’s life as a stray, Bob gets private walks, treats, belly rubs, and ear scratches.

The “beds” that the dogs are given more broadly symbolize the level of comfort, safety, and security of each dog through their very different lives: In contrast to Bob’s soft and comfortable blanket, Boss is grateful for the towel in the cage at the shelter. Bob notices this disparity and is ashamed of his privileged comforts as he feels undeserving of them. He resolves this guilt when Boss accepts his comes to live with him and when he provides the same happy home for Boss’s son Rowdy.

Bob cringes as he walks past the shelter and hears the desperate barks within. These dogs signify to Bob all the dogs who live without a loving, safe home. In particular, it reminds him of dogs from his past: Boss, his long-lost sister, and the neglected Droolius, who doted on an abusive and indifferent owner. The shelter makes Bob reflect on the fact that he has a home, but “the gang in there doesn’t” (76).
