I have had 3 GSD from Royalair in Grinnell Iowa & LOVE 'em. Sam was over 13 when I had to let her go & was not only long lived but healthy, vigorous, easily trained, terrific personality & rock solid temperament. Phoenix(just shy of 6) & Djibouti (6+yo) are with me now & have never had an unhealthy day. They're sound, active, lovely companions that I'm so grateful to have.
Royalair isn't popular on the board. Most of her dogs are over sized. IF you don't want a larger GSD you want to look elsewhere. IF SchH/IPO titles are important to you then you should look elsewhere. IF not then she's absolutely worth considering.
The vast majority of people who have Royalair GSDs & live with them, actually KNOW them, love them. Many return to Royalair again & again for their 2nd, 3rd & 4th GSD. Personally, that info is more important to me than rumour & speculation from people that don't have any 1st hand experience with the breeder or her dogs.
Wherever you go be certain to make a reasoned decision that is *your* decision & one you'll be happy with for 12, 13 yrs.
