The posting said that her beloved pet has "been there" with her "through it all." The Hollywood celebrity added that Hank was "the best dog ever" and that he had been "part of the family."
With that thought expressed, Richards also put up an Instagram photo of the sturdy little black dog who obviously had been a big part of Denise's life for a long and often stressful time.
In response to her heartbreak over the passing of her old pal Hank, hundreds of Twitter followers came to her aid by expressing their sorrow, too.
Some of these mourners were other celebrities who could relate. For instance, Holly Robinson Peet told Denise via Twitter that she was sorry about the tragedy and that she empathized, saying "how hard" it is to lose such a close friend.
Even the animal rights organization called PETA (which stands for People for the Ethical Treatment of Animals) reached out to Richards on the social media site, saying, "So sorry for your loss. Lots of love to [you and] your [family] during this difficult time." This thoughtful sentiment ended with the symbol of a tiny heart.
By way of background, Hank wasn't just a passing fancy for Denise Richards. During his life, his owner was married to and divorced from Charlie Sheen, had two daughters, and, later, adopted another two as well adopting a number of other pets that she also cherishes.
The French bulldog was also there when the former Bond girl went out with Richie Sambora after she split from Sheen. This was a move that came with considerable drama concerning the singer's ex-wife and Richards' Tinseltown neighbor, Heather Locklear.
And so, standing by while going through all of this turmoil that transpired in the life of Denise Richards life, her faithful dog, Hank, was there to comfort the troubled star whenever she was in need.
Indeed, the proverbial thought that "dogs are a man's best friend" applies but should be amended because, in this case, and in a whole lot of other cases as well, this dog was definitely a women's best friend. Right, Denise Richards?
