Kim Richards -- She's Gotta Pay Up for Pit Bull Attack

One of Kim Richards' best friends just won her lawsuit over a ferocious pit bull attack from Kim's dog last year.

Kay Rozario filed suit, claiming Kim refused to pay her medical bills after Kingsley chomped on her hand in March 2014 ... and bit clear down to the bone.

On Thursday, a judge ruled in Rozario's favor ... but severely limited the amount of damages Kim will have to pay. Rozario was looking for more than a million dollars, but according to court docs ... she was only awarded $8,083.53.

The judge pointed out ... Rozario's medical bills were only $4,083.53, but said she deserved some more cash for emotional distress and trauma after the attack.

Of course, Kim's dog also attacked Kyle Richards' daughter Alexia in November of last year. The dog is currently at a private training facility.

Kim never responded to the lawsuit ... so the judge entered a default judgment.
