Taylor Kinney & Jesse Spencer: 'Chicago Fire' Casts a Puppy!

Taylor Kinney and Jesse Spencer walk around the set of their show Chicago Fire on Tuesday (January 29) in Chicago, Ill.

The guys were joined on the set by their co-stars David Eigenberg, Monica Raymund, and Christian Stolte to film scenes for the NBC drama.

During this week’s episode, a new dog named Pouch was introduced to the series and he will grow up on the show!

“All firehouses have a million stories to tell about a firehouse dog, and we thought he would make a great addition,” executive producer Derek Haas said in a statement. “Pouch will literally grow up before our eyes. Plus, pets are great stress relievers, and firefighters and rescue squads are under tremendous pressure every day, so they will appreciate her presence as a working dog.”
