However, Kim's plan turned sour when her dog, Sushi, turned out to be something of a persistent yapper, while Kourtney's new pup, Honey, was calm as could be.
Kim first tried to pull off an ill-conceived (and kind of mean) clandestine dog swap -- in which she brought Sushi over play with Honey at her sister's house and then "accidentally" took Honey home instead.
"For my sanity, all I wanted was a really calm dog," Kim told Cesar, who explained that the dog's behavior was all due to a lack of structure and boundaries.
As Cesar observed Sushi playing with North and Kim, he soon came to realize just how many bad habits the little pup was picking up and how many training mistakes the mother and daughter were making -- including rewarding bad behavior and providing an environment where Sushi was allowed to run all over without being reined in.
However, after an afternoon with the Dog Whisperer, Kim had already learned a number of different techniques for calming her new dog, and was looking forward to spending time together.
"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 said in a solo interview.
