Also, Hijinks is not used to have a little sister around her. However, she looked excited to learn the ropes. “She started looking to us for cues on what to do,” Hijinks’ owner, Reddit user Rally8889, said. “She’s careful and quiet around the baby.”
Clearly, when it comes to making Mercury cheerful, Hijinks knows that practice makes perfect. The day after, while she rocked Mercury in a rocker seat, Rally8889 noticed Hijinks watching interestingly. Apparently, the dog was taking notes.
