Kim Kardashian has resorted to the help of 'The Dog Whisperer' to preserve her sanity

In scenes from the latest episode of 'Keeping Up With the Kardashians', Kim told Cesar: "For my sanity, all I wanted was a really calm dog."

The renowned animal trainer - who has helped celebrity clients including Jada Pinkett Smith, 'Frasier' star Kelsey Grammer and the late 'Playboy' tycoon Hugh Hefner - watched Kim and North playing with Sushi and quickly spotted the mistakes they were making.

Cesar told Kim that Sushi's bad behaviour was down to lack of structure and boundaries, pointing out they were rewarding the pup's misdemeanours and letting the pet have free rein of the house.

He taught Kim, 37, a number of different techniques to calm the puppy down.

She said: "It's really exciting to know that Sushi's issues are fixable, and she's just a part of the family now, so we gotta work on it."

Kim - who has son Saint, 23 months with husband Kanye West and is expecting a third child via a surrogate - previously tried to switch Sushi with her five-year-old niece Penelope Disick's dog Honey.

But her sister Kourtney Kardashian - Penelope's mother - ended up chasing Kim around her kitchen in a bid to retrieve Honey.

Kim insisted: "I swear she likes me better now. She's like, adjusted. Look how calm she is."

Kim eventually admitted defeat after Kourtney pointed out that her young daughter would be devastated if she lost her furry friend.
