Scotland Yard said the woman was assaulted by two men wearing caps with the word “Police” on the front in Arabella Drive, Roehampton.
The victim, in her 30s, suffered cuts and bruises after she was attacked when she refused them entry after they claimed they were there for a drugs search at 10am on Monday.
The pair searched the home making off with her two-month old female American XL bulldog puppy, which is described as ‘blue merle’.
Cash and a bag containing Christmas gifts were also stolen.
The victim was treated at hospital for injuries before being discharged.
There have been no arrests. Enquiries continue.
