So far there's no luck until Pongo sees mates that will suit both him and Roger. Pongo gets Roger to follow them into the park. Pongo tries to get there attention but it ends in a terrible. Although it seemed terrible the two Roger and Anita falls in love as does Pongo and Anita's dog Perdita. Years later the happy couples move into a small hame and Perdita becomes pregnant. The family is then visited by the villainous Cruella De Vil. She comes in the house smoking and she frightens Perdita and that gets Pongo truly upset. On a stormy night in October the puppies arrive, fifteen to be exact. Cruella De Vil comes once again requesting the puppies, but due to Roger's braveness, Cruella is sent away. She gets her henchman Jasper and Horace to kidnap the puppies although they do not like the idea. Pongo and Perdita then go on a journey to find their puppies and reunite with their families. He and Perdita rescue the puppies and reunite with their families just in time for Christmas.

Pongo reappears in the film's sequel along with everyone else. Pongo is accidentally the true reason his son Patch felt as if he was nothing more than a dalmatian puppy. Pongo is shocked at the fact that one of his own has once again disappeared. He blames himself for Patch being missing, because he lost count. He along with Perdita, Roger, and Anita head back to London to look for him. When they do, he tells his son how much they missed him.
