Perdita: The twilight bark? But dear, that's only a gossip chain.
Pongo: Darling, it's the very fastest way to send news. And if our puppies are anywhere in the city, the London dogs will know. Now we'll send the word tonight when our pets take us for a walk in the park.
How every dog in the city immediately looks concerned upon hearing the alert and stops what they're doing to bark and spread the news.
It's hard to tell whose adoption of the other 84 puppies was more heartwarming, the dogs or the humans.
"...But whaddabout the others? What'll they do?" Pongo and Perdita definitely raised their kids right.
"We'll take them with us. All of them." Just the way Pongo says it—it's beyond argument. The firmness of the statement is probably meant to reassure the other, non-Pongo puppies, who are looking horribly scared and vulnerable waiting for his answer.
Pongo is certain that Roger and Anita would never shut the other puppies out. And he's right, though it becomes a Crowning Moment of Funny later when Roger just assumes that the large amount of puppies is attributed to Pongo's, er, prowess.
At the very beginning, Pongo being worried enough about his Roger that he starts scouring the street below for potential "mates" for him (and admittedly, for himself). And succeeds!

Deleted scenes reveal that the last day shown in the movie in which the dogs make it back to London is in fact supposed to be Christmas Eve.
The scene after Cruella leaves the house for the first time, where Roger comes downstairs still singing and proceeds to waltz with Anita while she semi-seriously remonstrates him for being so flippant, ending with a sweetly passionate kiss. A perfect little vignette of newlywed love.
Even while they're tied up in a dog leash, Roger will take off his hat and say "I beg your pardon!" to Anita. He may be a bit scatterbrained, but he's also a gentleman.
