What is the breed of fran dressner's (the nanny) pet dog

pomeranian

Fran Drescher has a chocolate brown Pomeranian named "Little Esther."

The dog's name is Chester. He was a red Pomeranian. It was her real life dog too. She adopted him from a pet store and took him to work, before he knew it, he was no longer just a pet, he had became a working dog and a celebrity loved by many. Fran had to have him put to sleep after 18 years of them being together due to the effects of old age on Chester. I hope that is helpful.
