Kyle Richards — Daughter Viciously Attacked By Kim Richards’ Pit Bull

EXCLUSIVE

Kyle Richards‘ daughter was the victim of a vicious pit bull attack … a dog owned by Kyle’s own sister Kim, and the hurt was so severe it required multiple surgeries.

We’re told 18-year-ancient Alexia Umansky spent the weekend at Cedars-Sinai Medical Focal point, undergoing 2 surgeries.  

The attack occurred early Saturday at Kim’s L.A. area home. Kyle, Alexia and other members of their family had been inside the household for a while, when the dog went into attack mode out of nowhere.

The dog bit Alexia numerous times, but the worst was on her right hand. The animal bit through her thumb right to the bone.  She’s had one surgery and will undergo another.

The pit bull has a history of wounding. It attacked it’s trainer on an episode of “Real Housewives of Beverly Hills.” It’s also been very aggressive toward other dogs.

Kim is still keeping the animal at her home. The Dept. of Animal Control was never called. We’re told they wanted to keep it “private.”

We reached out to Kim and Kyle … so far, no word back.
