Nice Doggy(1952)

The Terry-Bears hear howling and waken their father, who is also frightened. A big dog comes in, and the cubs want to keep it but Papa Bear kicks it outside. The kids get the dog back inside and Papa decides to get rid of it and takes it away in his car. A traffic-cop is knocked down and gives chase. Later, the Terry-Bears are happy when the dog returns on his own, wearing a policeman's cap, while Papa Bear is in court giving an explanation to a judge.
