The following story was in the New York Post in the Page Six section:
March 6, 2007 -- RACHAEL Ray was attacked by a dog in Union Square Park Saturday while bravely defending her pit-bull mix, Isaboo. According to the TV host's rep, "This dog came up - there was no owner in sight - and became aggressive. Rachael and some others shooed it away, but it came back and attacked Isaboo. Other dogs were involved, and Rachael jumped in and was bit by one of the dogs on the leg. A nurse was in the park and checked her out. She's fine."
I wonder where the owner was? Oh, that doesn't matter, it was during the offleash hours.
