Saw this in a friend’s Facebook post:
The actress is Eleanor Powell, and the scene is from the 1941 musical comedy “Lady Be Good.” Here’s the key to the scene (From YouTube(:
Eleanor Powell trained this dog herself and this scene was shot in her own living room because it was where the dog was used to do all the tricks.
If she trained the dog herself, it sounds like it was her dog. And if this was done in her living room, she must have been rich, because that’s an impressive dance space..
