Chad Michael Murray posted a touching tribute to his late dog Joe on Monday.
"My best bud & 1st born son Joe, Thank you for everything you've ever done for me. You've been my kindred spirit, my unconditional friend, " he captioned the Instagram photo collage. "Thank you for carrying the weight that I could not. You taught me more about selflessness and compassion than I thought a dog could know. Thank you for always keeping the status Quo. Even the dogs at the dog park thank you for keeping the peace. Almost 15 years of adventures Joe and I'm so grateful for every minute. Rest easy now bud. Check in on us once and while would ya... You're missed and always will be. Thx for waiting to meet my son. This family won't be the same without you but so much stronger because of you. Rest in peace Joey. We Love You, Chad, Sarah & Baby Murray."
The One Tree Hill actor and his wife, Sarah Roemer, welcomed a baby boy on May 31 of this year.
Chad's "1st born son" and the new baby were able to cross paths briefly before the dog passed away.
The 33-year-old actor mourns the end of his beloved pet's life, but he also has much to celebrate with the new family member.
He told Bello magazine about becoming a dad, "the greatest thing in the whole world. I'm going to sit back and enjoy this new chapter."
