Pongo

Pongo is a character on ABC's Once Upon a Time. He makes his début in the first episode of the first season. He is Archie Hopper's Dalmatian dog.

During the Curse
He is almost always seen with his master. Pongo is extremely loyal and always listens to Archie. He has a very good sense of smell, as he could smell Henry, who at the time was hundreds of feet below him.

After the Curse
Pongo is the only witness to Archie's simulated murder created by Cora. Using the dream catcher given to her by Mr. Gold, Emma is able to see the false events that have been perceived by the dog. ("The Cricket Game")

Pongo attends Archie's false funeral and afterwards Marco and Emma decide that now that Archie is gone it would be good for Henry to keep him. Henry is thrilled at this and takes Pongo outside to clean him up. Later on, Emma and Henry notice that Pongo is acting strangely. Soon afterwards Archie is at the door. He tells them the true events of what happened, how Cora was the one who kidnapped him. ("The Outsider")
