Oh, don't let me scare you. Feeding raw is rather safe for the most part, but there are definitely risks and it's always good to expect the unexpected

As for dentals, do it as much as is necessary. Giselle got her first dental in Feb because it was oral health month and they were handing out promotions. With the exam and bloodwork, it costed a total of about $500. Lucky needs a dental so he'll be getting his soon, but I don't think Ivy will ever get a dental in her life. It's too pricy to do "just because" =P
