Khloe Kardashian's dog has passed away.

The 'Keeping Up With The Kardashians' star is ''devastated'' by the passing of her canine friend, a black Labrador called Gabbana, who she says has stuck by her side through absolutely everything.

She wrote on Instagram: ''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 loosing 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! (sic)''

Following the post, the 33-year-old television personality - who is expecting her first child with her partner Tristan Thompson - took to Twitter to thank her fans for their kind messages of support.

She added in the tweet: ''Thank you for being so loving and kind in regards to Gabbana! It's been such a sad night and an even sadder day. Thank you for the love.''

Meanwhile, it has been a tough time for Khloe as she previously admitted that her pregnancy is both ''physically and mentally trying''.

She explained: ''Having a partner that is equally as excited as you are, and is such a support system, is crucial!

''Tristan has been an angel to me! This process is trying - physically and mentally - but Tristan has made everything as easy and beautiful as it can be! More than I could have imagined.''
