In the video, which Cox shared on her Instagram account on Saturday, July 18, one of the ladies' pups is shown with a protective face mask in its mouth.
"Just put it on," the closed captioning reads over the first dog. The camera pans to a second dog who answers, with the help of closed captioning, "No!!"
The mask-carrying dog pleads, "I'll make it worth your while. Come on now." Convinced, the other dog takes the mask and the original mask-wearing pup commends the dog, "I've never been more attracted to you."
The video, which features the song "What Can We Do?" by Anderson Park featuring Nate Dogg, ends with Aniston and Cox snuggled up on the couch with the two dogs. Both ladies wear blue tie-dyed masks, while the dogs opt for white disposable ones.
Cox simply captioned the video with two pink hearts.
This is not the first time Aniston has promoted mask wearing on social media. On June 30, the actress posted a selfie showing herself wearing a black mouth and nose covering.
"I understand masks are inconvenient and uncomfortable. But don't you feel that it's worse that businesses are shutting down… jobs are being lost… health care workers are hitting absolute exhaustion. And so many lives have been taken by this virus because we aren't doing enough," the 51-year-old wrote on Instagram.
"I really do believe in the basic goodness of people so I know we can all do this. BUT still, there are many people in our country refusing to take the necessary steps to flatten the curve, and keep each other safe. People seem worried about their "rights being taken away" by being asked to wear a mask. This simple and effective recommendation is being politicized at the expense of peoples' lives. And it really shouldn't be a debate. If you care about human life, please… just #wearadamnmask and encourage those around you to do the same."
