Brandi Glanville has fired her assistant for losing her dog.

The 'Real Housewives of Beverly Hills' star is blaming her 23-year-old former associate after her beloved Chihuahua, Chica, was snatched from her home in Los Angeles during an alleged break-in last week, while she was in Palm Springs, California.

The assistant - who has asked not to be named - told ''I no longer work for Brandi. She texted me [last Saturday] saying that I didn't do my job by losing the dog.''

The personal helper claims the 40-year-old star still owes her for two weeks work, totalling up to more than $1,000.

However, Brandi seems unsympathetic towards her former worker, saying: ''I did what I had to do. If I can't trust her with my dogs, how can I trust her with my kids?''

The blonde beauty - who has sons Mason, nine, and Jake, five, with her former husband Eddie Cibrian - has offered a generous $10,000 reward if her brown pooch is found, but in the meantime has welcomed a new dog named Chico into her home whilst the search for Chica continues.

She wrote on Twitter on Sunday: ''We have a new family member until Chica comes back to us. His name is Chico. (sic)''
