We recently adopted a puppy from someone that bought her from a very reputable breeder. She comes from a strong lineage of Schutzhund/IPO dogs. Unfortunately, her energy level and drive made it very difficult for the previous owner to incorporate her into his family, and after having her for 3 months now we feel that she's going to need to be involved in either a sport or service to be truly happy. In other words, we just don't feel that she's the type of dog that will ever be satisfied with "chilling" most of the day like our other 2 GSD. She's now 7 months old and still needs a lot of work on obedience/manners. We're in the process of finding a new trainer for that since the current situation doesn't seem to be a good fit. But we've also never been involved in Schutzhund/IPO or any other sport/service for that matter so we are complete newbies and need some advice on where to start. Any suggestions would be greatly appreciated!
