Kaley Cuoco recently shared a photo with one of her rescued dogs, Rex, who accompanied her to the set of “The Big Bang Theory.” On her Instagram account, the actress shared that Rex usually goes to set with her. In the black and white photo, Cuoco wears a black thermal jacket as she holds Rex to her chest.

One of the actress’ followers said that Cuoco’s Penny and Johnny Galecki’s Leonard should get themselves a dog, so Rex could also be part of “Big Bang Theory.” After all, Leonard and Penny are now living together, and they still don’t have a baby to take care of.

Meanwhile, a new episode of “Big Bang Theory” Season 10 aired on Thursday night. One of the scenes was centered on Penny and Leonard choosing, cutting down and bringing home their Christmas tree. Before “The Holiday Summation” aired on CBS, Cuoco shared a photo of Penny taking a picture of Leonard while the latter was lying on the ground with the huge tree on top of him.

In other news, Cuoco and Galecki will have a major storyline in “Big Bang Theory” Season 10, episode 13. In “The Romance Recalibration,” Penny thinks that Leonard is taking her for granted just after a few months since they got married. As a result, Penny will temporarily distance herself from Leonard by inviting Amy (Mayim Bialik) to go on a spa date with her. When Leonard realizes that Penny is upset, he will most likely come up with a plan to make it up to her.

Elsewhere, Bernadette (Melissa Rauch) and Howard (Simon Helberg) will continue to deal with Hallie’s nonstop crying. Despite their struggles as new parents, however, the couple will receive support from all of their friends.

“Big Bang Theory” Season 10 airs Thursdays at 8 p.m. EST on CBS.
