First off, has anyone ever heard of an Affenpinscher? Its a kinda rare breed of dog that originate from Germany. They have the nickname monkey dog -----> here is a pic http://www.breederretriever.com/photopost/data/751... (you can see why they have that nick name) ANYWAYS i have one, her name is Izzie shes great but shes a little bigger than usual. The breed is supposed to be 12 to 15 pounds and Izzie is 30. Shes not fat or anything, shes tall and long. Does anyone know enough about this breed to know why shes so big?

Thanks!
