North West‘s adorable new puppy is taking after her famous family and breaking the internet, but there’s another purpose for the pet.
A source close to Keeping Up With the Kardashians tells PEOPLE that Kim Kardashian West hopes bringing the still unnamed dog into the family will teach her daughter about responsibility.
“North has been asking for a puppy for a long time,” the source says. “Kim thought it was a good idea for North to take care of a puppy. It could prepare her for baby sibling too.”
“She really misses having a baby in the family,” a source close to the reality star tells PEOPLE. “They looked for a while before they found the perfect surrogate.”
On Thursday, Khloé Kardashian shared a new photo to Instagram that stretches the limits of adorable starring North and her fluffy friend.
“My little Northie! This face 😍😍,” “Auntie KoKo” — captioned the super-cute moment.
