Kelly Osbourne is worried about her sick dog.

The 'Fashion Police' star's Pomeranian, Sid, has been vomiting a lot recently and despite Kelly taking him to the vet three times, the pooch isn't getting any better.

She wrote on twitter: ''sid keeps throwing up he has been to the vet 3 times and its still happening I'm starting to get worried i think my dog is puppy-rexic! (sic)''

Perhaps Sid needs another trip to the spa where earlier this month Kelly treated him to a special day where he was pampered in a fashion which would have been luxurious even by human standards.

She tweeted: ''Sid just came back from the doggy day spa he had a blue berry facial, oatmeal bath, many-pedy & blow dry he looks #scrumdiddlyumptious (sic).''

Dog lover Kelly,27, owns two pooches, Sid and a Doberman she named Blue, who was bought for her by her brother protective younger sibling Jack because he was worried about her living alone.

Kelly said: ''My mum and Jack get nervous because I live alone. So Jack has got me a dog that he'll train for six months to be my little protector. I've already got Sid - who thinks he's much bigger than he is - but let's face it, he won't do much other than bark at an intruder!

''The new dog, Blue, is a beautiful blue Doberman - but don't worry, she's not being trained as a killer! We just want her to be protective.''
