The young pups cast as Rollo for “Outlander” season 4 made quite a wave when their pictures were released in May last year. These pups were first cast for next season because the producers wanted them to get used to the actors, hence allowing the shoots to go smoothly. Now, leaked pictures from the production set show the pups all grown up, ready to play the important character.

The pictures posted on YouTube show a grey-brown dog. The identical pups playing the same character have come a long way. The pictures show the dogs all on their own, playing at the filming location. None of the cast members was seen working with the dogs. Fans who have read Diana Gabaldon’s books will know that John Bell (Young Ian) will be the one to interact with the dogs the most.

Bell has been filming his scenes with Sam Heughan (Jamie) and Caitriona Balfe (Claire). Previously leaked pictures from the set showed the actor in action.

This is not the first time a dog is playing an important role in the TV series. Fans loved Mother Hildegarde’s (Frances de la Tour) little dog called Bouton. The dog was very helpful to Claire at L'Hôpital des Anges in Paris, France, thanks to its ability to sniff sickness.

It will be interesting to see how Rollo manages to win the hearts of fans in “Outlander” season 4. Filming is currently ongoing, and the show is set to premiere sometime later this year.
