The Medicine Show is a 1933 short animated film by Columbia Pictures.
His second act features a lady wolf being inside a wooden box which Krazy saws into four pieces.
But instead of his assistant being divided, four small lady wolves pop out of each piece.
After doing his acts, Krazy starts retailing his bottles of liquid medicine.
The old beagle, after consuming a bottle, suddenly becomes very able and dances very fluently but also transforms into a small puppy who merrily leaves in a scooter.
