Khloe, 35, made the difficult decision to put Gabbana down in January 2018.
"I will never forget you! I could never forget you! I miss you Goober," Khloe gushed on her Instagram Story, using the dog's nickname.
She continued, "I think about you always and how much you and baby True would be in love with one another."
"Last night my sweet Gabbana passed away. She was more than a pet. She was my first child, my companion and my friend. She was incredible! She made sure I was never lonely even during lonely times. The house will never be the same. I never thought I would be this devastated over losing a dog but 14 years is a long time together. She filled a significant role in my life and I'm forever grateful. I love you Goober!! I'll remember you always!" she wrote on social media.
