This Moose Belongs to Me (Jeffers)

Wilfred is a boy with rules. He lives a very orderly life. It's fortunate, then, that he has a pet who abides by rules, such as not making noise while Wilfred educates him on his record collection. There is, however, one rule that Wilfred's pet has difficulty following: Going whichever way Wilfred wants to go. Perhaps this is because Wilfred's pet doesn't quite realize that he belongs to anyone.
