Westminster to me was fairly perdictable. While it use to be a show I respected and marked my calendar for, its turned into one big political show. Basically the #1 dogs in each breed go up for breed, and if not something of "course" was wrong with breed judging. Groups is always perdicitble with: who has the best handler. I did think it was a awesome win for the akita and the bouv. BIS winner was not my cup of tea, but he also won Eukanuba in Dec. so again, fairly perdictiable.
As for Vivi, there are some breeds that will breed a dog before they are 2, beagles, pugs, bulldogs, even some ACDs to just name a few. And the people that do this are not some backyard puppymillers, they are well respected breeders who have some of the finest dogs in the country.
As for her being alive, I think there have been sightings, and somewhere in the net I think it was that she had been seen and looked liek she was nursing puppies. But who knows.
