A Story of Dogs

I had the pleasure to find the first part (the Lady and the Tramp half) on the internet. Very insightful, and although it's a condensed version of how the actual process might have undergone, it's still a very welcomed behind-the-scenes bit.

One of the main highlights of the episode is when they show off all the different versions of the Tramp and how they brainstorm about animating him in certain situations. But I was surprised that they did not mention his origins; Happy Dan the Cynical Dog by Ward Greene (they DO mention it in the 2006 Platinum Edition re-release of the movie).

If you try hard enough, you might find some lost bits on the internet about how the Siamese Cat Song and He's a Tramp got to be made, the former being more in depth, even showing the writing and recording process.
