Just Dogs 1932

Pluto's cage-mate at the dog pound breaks out and lets all the other dogs out as well. In the park, that terrier keeps following Pluto too closely for Pluto's tastes, until he digs up a huge bone and gives it to Pluto (who doesn't particularly want to share). But soon all the other escaped dogs are chasing after the bone.
