As for what Kim's issue with Kyle is, a source recently claimed her biggest problem is Kyle's behavior in regard to her dog attacking her daughter, Alexia Umansky, which left the child hospitalized and in need of multiple surgeries.

“Kyle's mad because she thinks Kim doesn’t back her up, and Kyle thinks she is always backing Kim up," a second source added.
