The Surprising Connection Between 'Severance' and 'Succession' You Probably Never Noticed
Ditto the dog played Irving's dog, Radar, in Severance, and Shiv and Tom's dog, Mondale, in Succession.

There have been many TV shows about business dynasties in recent years, from the Roys in Succession to the Eagans in Severance, and, curiously enough, one actor has managed to be on both these shows. This isn't a human actor, however, but a canine one: Ditto the Dog. This was revealed on X by Severance director Ben Stiller himself and later confirmed by Sarah Snook, who worked with Ditto the most in Succession, because he plays Shiv Roy's and Tom Wambsgans' (Matthew Macfadyen) pet, Mondale. In Severance, however, Ditto is not an Eagan, instead playing Irving Bailiff's (John Turturro) loyal companion, Radar, in both seasons.
