Vicious Dog Bite! Kyle Richards' Daughter Alexia Umansky Left College, Nearly Lost Finger After Attack By Kim Richards' Pet

As Kyle Richards' daughter Alexia Umansky recovers from a bite from Kim Richards' dog, RadarOnline.com has exclusively learned that she left college after the vicious attack.

Umansky's recovery from the dog bite she received last year has been far worse than has been previously reported, and not only did she have to leave college for treatment, insiders said that "the recovery is an intense, long road."

The vicious attack by Kim Richards' dog on her niece has been a focal point on The Real Housewives of Beverly Hills this season, and a source told RadarOnline.com that Kyle feels that her sister has let her down in dealing with the situation.

"Kim is being a hypocrite," the source said, after RadarOnline.com's extensively reporting that she refuses to have the dog put down -- and that the "rehab" the animal received has not been helpful. "If it were one of her kids, she'd be p*ssed."

The source also revealed to RadarOnline.com that Umansky moved home, and is living in Los Angeles to heal.

"She is missing an entire year of college because of it now, and she may have to reapply and go somewhere else -- it was BAD."

For the first time, RadarOnline.com is revealing the extent of her injuries.

"It was really serious, and a few millimeters deeper, she would have lost a finger or need amputation," the source explained. "Alexia had to get physical therapy and reconstructive surgery.

"This changed the whole course of her education and really her life … she may still need future treatment."

However, the source said her caring mother has been monitoring her progress.

"The recovery is an intense long road -- she's healing though, and naturally, Kyle had the top plastic surgeons treat her."

As RadarOnline.com previously reported, an insider revealed: "Kim accepts absolutely no responsibility for the dog biting incident, which makes Kyle absolutely nuts.
