I believe that you are describing what was known as Looney Zoo which was filed live on Saturday mornings in the old WMC studio before they moved to Union Ave. Then they were known as WMC-TV channel 5. There was a companion that was with him whose name was Tiny the Clown not Tramp as I remembered.
Also there was a show that aired on Channel 13 located on Highland Ave known as the Hart's Adventure Time as sponsored by Hart Bread which featured the adventures of "Buck Rogers in B&W.
