Who Plays Wags on Billions
The short answer is that the dog playing Wags is handled by professional animal trainer Annie Lail Davis, who works with the mixed-breed performer off-camera. On television, the character is credited simply as "Wags, played by a dog," with the real recognition going to the team that trains, cares for, and directs the pup on set.
In high-pressure shows like Billions, animal scenes must feel unplanned yet safe, which is why the production leans on a skilled trainer who understands canine behavior and can deliver reliable cues without forcing the performance.
Animal Training Process Behind the Scenes
Creating natural dog reactions for a financially tense drama requires careful choreography and a lot of repetition. The trainer builds specific behaviors like sitting, walking alongside chairs, and looking at treats hidden in pockets, then layers those into longer takes that match the scripted rhythm.
Because Billions often films in sophisticated, low-light interiors, the team adjusts training methods, uses subtle markers and rewards, and ensures the dog remains comfortable with lighting rigs, cameras, and constant crew movement while maintaining relaxed body language.
Role of the Dog in Storytelling
Wags functions as both a grounding presence and a symbol of normal life amid intense dealmaking and personal conflicts. The dog’s reactions, pauses, and movement are used by editors and directors to modulate pacing, break tension, and offer brief emotional connection for the audience.
Because the trainer and owners understand the character’s narrative purpose, they emphasize calm, deliberate behaviors that match the scene’s tone, ensuring the dog supports the storytelling rather than distracting from it.
Collaboration Between Cast, Crew, and Trainer
On set, the actor, director, and animal trainer align on precise timing so that looks, entrances, and exits feel organic. Simple techniques like marking desired outcomes, using quiet verbal cues, and managing the dog’s environment help integrate the animal seamlessly into complex scenes.
This close cooperation also protects the dog’s welfare, balancing work periods, rest, and enrichment so that Wags remains engaged and unstressed throughout long shooting days on a high-profile series.

- Coordinate timing with the director and editor to match the dog’s actions with scene pacing.
