Baxter is a character in Back at the Barnyard. He is Duke's arch-nemesis.
In his debut episode "Doggleganger," Baxter disguised as Duke with the help of black spray paint to give him spots and markings like Duke's. Although Baxter seemed to be a stray, he might have had an owner in order to be able to afford medical care. He made 2 more appearances, first as Duke's replacement on the Barnyard, and then tried to marry Duke's sister Stamps, only for the fact she was second in line to a relative's priceless bone collection.
Baxter is a small white dog with pointed ears.
