It wasn't anything you did-- the shunts that we find in yorkies are hereditary. That doesn't mean that every dog that came from the breeder will have a shunt. My own dog was one of a litter of two pups. Her brother had a shunt that required surgical correction, but my Penny is 100% okay.
You may want to have a BAT run on Simone just to make certain that everything is as it should be. Not all shunt cases are extreme enough to warrant surgery-- some dogs can be treated by changes to diet and some medications-- and sometimes shunts can go undetected for quite a long time if the dog isn't presenting many symptoms. The BAT isn't too expensive, and might offer you some peace of mind.
I think it is pretty mean of the breeder to suggest that it was your fault-- if she honestly believes that to be the case, it displays a severe lack of knowledge of the breed's hereditary issues to say the least.
