The 'Keeping Up With The Kardashians' star was gifted the dog, which she named Penny, by her best friend Jordy Woods and couldn't help but gush about the new addition to her family.

Sharing a snap of her new pooch on Instagram, she captioned it: "Mom duty."

She also posted a number of videos on Snapchat where she filmed herself showing Penny - which was a gift for her 19th birthday next month - around her new home.

And Scott Disick recently admitted he is unsure what to buy the 18-year-old television personality - who also has a dachshund called Ernie and three Italian greyhounds, Norman, Bambi and Sophie - for her birthday as she has "everything".

He shared previously: "She's got everything. Honestly, in our family it's not so much about materialistic items anymore because everybody does have it. Really, it's the love and support and being present for everybody. That's what's most important to me, and I think that's what's most important to everybody now."

Meanwhile, it is likely that Kylie will spend her 19th birthday with Tyga after the pair rekindled their romance.

A source said: "Kylie and Tyga are giving things another shot. They are taking things a lot slower this time around, though, and are using their former arguments and fights as a learning curve and as a reference point for a healthier future.

"She can't resist him and he can't resist her. They are still so in love, so getting back together was relatively inevitable. They both knew that but needed their space to decompress and regroup and grow."
