Hey everyone I've been looking into getting a Working Line GSD more and more so I'm educating myself on lines, temperaments, training, exercise etc. Though this is a working breed and they require lots of consistent training and exercise throughout their lifetime, what's a day in the life like with your DDR? What do you guys do training wise to get them mentally stimulated so they're satisfied? What about how much exercise you give your DDR to the point where they're content enough to settle and be happy? This dog would be a Service Dog prospect (though it's not the best choice for some people GSD's fit me well I'm just looking into working lines more instead of show), we'd also possibly get into other sports like obedience, rally and many others out there. I have experience working with many breeds but haven't had the pleasure of working with specifically purpose bred working lines. There's only a certain amount of information I can find on the internet with articles so if you could refer me to any that'd be greatly appreciated!
