Page Six (one of the "attacked" offenders) reports that Rachael was walking her pit bull, Isaboo, in Central Park when a dog without an owner approached. Rachael and others shooed the dog away. Then the dog came back and attacked Isaboo. Rachael jumped into the middle of the fight to defend Isaboo and was bitten in the process. A nurse on the scene checked her and and she's just fine.
So, Rachael was not attacked by a dog in Central Park. Her dog was attacked by a dog in Central Park and she got bitten while breaking up the fight. Isaboo is lucky she has such a brave owner.
Check out some pictures of Isaboo in the Isaboo's Spot section of Rachael's talk show website.
