Carrie Underwood is sending love to her friend and fellow country music star, Miranda Lambert, after the death of her dog Waylon.

Lambert turned to Instagram on Thursday (October 22), to share the heartbreaking news that her dog Waylon died after almost 13 years with her. "Today I lost one of my best friends. My old pal Waylon," she wrote next to a series of pictures of the golden retriever.

"I found him and his sister on the side of the road in Oklahoma in January 2008," she recalled. "They were abandoned , starving and freezing nearly to death. I was listening to Jessi Colter and Waylon Jennings at the time me and mom saw them and pulled over to pick them up. I took them straight to the vet and she told me that the little boy was not doing too well (malnourished and dehydrated ) because whatever they had found to eat while they were homeless, he always let her eat first."

"He did that nearly his whole life," Lambert continued. "She said he probably wouldn’t make it but he did. For almost 13 years. He was a rock in our family and always held down the fort. He lived his life with no fences. The way we all want to live. He was a farm dog through and through and retired to Nashville life riding on the bus with mama to go home to Texas for Christmas every year. I’m so thankful for the time we had with him and I’m thankful for the rest of the time we have with his sister Jessi."

"Im so glad my husband @brendanjmcloughlin got to know him in his final years.💙 We are heartbroken but happy that he is running across the rainbow bridge right now and will be waiting for us when we get there. 🌈 Dogs change your life," the "Bluebird" singer wrote. "The bond is something that can’t be described unless you have lived it. Thank you @sarahananney @julianentwig and @t_man_photo for being his other moms and dad and taking such care of him when I was gone."

Messages of support from fans and several fellow country stars including Underwood poured in. "😢...sending lots of love and hugs," Underwood commented under the post," while Randy Houser wrote, "Sorry buddy. I don't wanna even think about losing our boy. Love to you all."

Ashley Monroe of the Pistol Annies also chimed in writing, "Big handsome boy, he took care of everybody so well for so long." Jason Aldean's wife, Brittany Aldean, also shared some love writing, "Nothing like the love of a dog😔 so sorry, girl💔 praying for y’all."
