The entire relationship between Lady and Tramp is archetypical female fantasy relationship fodder:

Lady, the virtuous, innocent female, is whisked off her feet by the bad-boy street-savvy Tramp, falls in love with him, rescues him, tames him, and they live happily ever after.

Ah the 50's. Except that's not how reality works.
The funny (read: sad) thing about this is now (65yrs later) there are no virtuous innocent females to complete this trope. RIP society and RIP Disney.
