I'm looking for a bichon puppy

Does anyone know where I can find a Bichon puppy?

Our dog, Nestle, died awhile ago. She was a beautiful mix of Brittany Spaniel and German Shorthair Pointer - brown and white and spots on her belly- chocolate chip drops I think. She was 12 when she died and I really miss her. She was a shelter dog.
I have allergies and was just lucky that she never bothered me- I've read about all kinds of dogs and the Bichon is small and has hair not fur - and is supposed to be allergy friendly. I've read that even though they are small - they are sturdy. With 6 grandsons I need a pet that is playful but not threatening.
I live in northern NY on the Canadian border, but I'd be willing to travel to find one.
I'm terrified of puppy mills and would not consider a dog that wasn't family raised.
I saw a beautiful puppy online ( 2 actually ) from a place in Knoxville, Tn. but that's quite a drive all the way from here : ) - and I'm not sure about buying a puppy online....how would you know if it's healthy and from a good breeder....
Anyone have any ideas ?
