Saying goodbye to a pet is one of the hardest things in the world, but it’s even worse to lose two pets in a short amount of time.

Recently, country star Miranda Lambert announced the heartbreaking deaths of two of her rescue dogs, who died within 6 weeks of each other.

But in her grief, she used the opportunity to advocate for rescuing dogs — read on to see her heartfelt tribute:

The “House that Built Me” singer, 40, announced in a two-part social media post that she recently said goodbye to two of her rescue pets: her Chihuahua-pug mix Delta Dawn and her Great Pyrenees Louise.

Rest in peace, Delta Dawn and Louise

“In the last 6 weeks, two of the best and most loyal friends I have ever had have left this earth,” Lambert wrote in an Instagram post.

Describing Delta Dawn as “one of those dogs that you only get once in a lifetime,” she recalled finding her at a Sonic in Oklahoma in 2009. “She was homeless and hungry but still full of personality,” Lambert recalled.

“I opened my car door and she jumped in. Little did I know when I was trying to just get a cherry limeade, I would meet one of the most amazing dogs I would ever know. I had about 16 years with her and she was on almost every tour I’ve ever been on. I’m honored to have met her and learned so much from her.”

She wrote that Delta Dawn passed away on April 22. Just weeks after that loss, Lambert said goodbye to another one of her rescue dogs, Louise.

Lambert adopted Louise and her sister Thelma from a shelter in 2016, and took them to live on her farm in Nashville, where they quickly made themselves at home and became the farm’s protector dogs.

“The first day I ever brought them to the farm … they were right at home,” Lambert wrote. “I have mini horses, chickens and goats and I needed them for protection for the critters. And boy did they do the job.”
