Diane Keaton's final Instagram post was all about wishing her followers a happy National Pet Day. The post, from April 11, was made in collaboration with Hudson Grace, the home decor company which sold Keaton's collection. "Proof our pets have great taste too!" the company wrote in the caption, alongside a photo of Keaton with her golden retriever, Reggie, and some of the products from her line. "Happy National Pet Day from HG & Diane Keaton." The post also included photos of Reggie modeling one of the dog beds that are part of Keaton's Hudson Grace collection.
