Lauren Conrad is mourning the loss of the eldest of her three rescue dogs, Chloe, who passed away on Wednesday.

The reality star-turned-designer has had the Lab-Shepherd mix as far back as 2009 when she was still filming MTV's The Hills.

In fact, Lauren's beloved pup has been in her life at least three years longer than her husband William Tell, whom she began dating in 2012.

Conrad received public condolences from L.A.'s Finest actress Jessica Alba as well as The Hills: New Beginnings stars Stephanie Pratt and Mischa Barton.

Throughout the years, the SoCal native enjoyed dressing Chloe up in flower crowns and cute hats as well as Halloween costumes like police officer, lion, and hot dog.

Lauren and the 39-year-old guitarist went on to adopt a small companion called Fitz for Chloe in October 2012.

'With Liam, we didn't decide [on a name] until he was born. We had options, but we liked the idea of meeting our baby first,' Lauren told People earlier this month.

'The biggest thing [with this pregnancy] is that I already have a child this time. I’m definitely more tired. Pregnancy is much more difficult when you have a two-year-old running around.'

The Asking For A Friend podcaster called it 'a huge convenience' to partner up with Amazon's online Baby Registry to get essentials like a $906 self-rocking SNOO Smart Sleeper.
