In the first photo Aniston posted to her Instagram Story, Lord Chesterfield is lying on top of her yoga mat. The actor captioned the pic, “My workout buddy.“ae0fcc31ae342fd3a1346ebb1f342fcb While Lord Chesterfield looks pretty big, he’s still a young guy. Aniston shared that she adopted him in Oct. 2020. He was tiny at the time, but as shown in this pic of her pup from Thanksgiving, Lord Chesterfield grew a lot in a very short period.

She captioned this one, “Well, that’s KIND of the idea…” Maybe he wasn’t that into working out, or maybe he just really loves bones. When she first got him, Aniston posted a video of Lord Chesterfield sleeping mid-chew. “Chesterfield, have you fallen asleep with your bone in your mouth?” Aniston whispers in the clip. “I think you have.” In addition to Lord Chesterfield, Aniston has two more dogs, Clyde and Sophie. The 52-year-old actor has also shared photos of them on social media. For instance, she posted pictures of “bring Clyde to work day” in Nov. 2019, and in early 2020, she posted about Sophie’s taste in TV (she loves The Bachelor). Aniston previously shared the two pets with her ex-husband Justin Theroux. They also had a third dog named Dolly, who passed away in 2019.

Before Dolly, Sophie, Clyde, and Lord Chesterfield, there was Norman, Aniston’s dog who died in 2011. In his honor, she got his named tattooed on her foot. During an interview with Inside the Actors Studio in 2011, Aniston was asked her favorite word and said, “Norman.” She also explained that her love for the pup helped her get into character when she was working on the 2008 film Marley & Me about a family and their dog.
