13 Reasons Why has become one of the most talked about TV shows on Netflix. Anyone who has watched the show knows that the show deals with a lot of gut-wrenching, touching, and serious topics. The show hits on issues such as teen suicide rate and bullying. For someone watching the show, it can be extremely tough. But it was also overwhelming for the cast and crew.

In fact,  in a recent PopSugar interview with Katherine Langford, the actress who plays Hannah Baker, revealed “There’s a scene we do in episode 12 that is physically hard to do, just as a human being,” she told PopSugar in the same interview. “It’s only been after the show and after wrapping that I’ve gone, ‘Wow, we really did handle some really heavy stuff.’ I’m really proud of how we handle it, because as you said, we don’t shy away from them.”

Since the show was so emotional, producers hired a group of acute therapy dogs that they can cuddle up with between scenes.

“There was a puppy per hour,” Dylan Minnette, who plays Clay Jensen, told PopSugar. “They really tried to help out. The puppies helped.”

Catherine also revealed there was a lot of support for the cast on the set. It was all thanks in part due to the executive producer Selena Gomez.

“I don’t think I can emphasize how generous she is and how genuinely she cares,” the actress explained of Gomez.

As for Dylan, he noted that Selena “makes us feel very loved and welcome,” which is great for any job, but especially for an acting job.
