At the end of the episode, Karen didn’t seem totally sold on the idea. But she also didn’t outright say no to getting a dog. On Instagram, however, it doesn’t look like the Couples’ Cam pair have adopted a dog just yet. In a Q&A, Karen mentioned having a lot going on in their lives.
So for now, they may still not have enough free time to dedicate to a puppy. If Miles remains persistent, though, he might eventually get his way.
