So, first time GSD owner. Getting ready to start Schutzhund training next week. Nika is 7 months old - almost 8 months. My wife and I are arguing about whether to train in German or English. I’d like to do the traditional German commands, but my wife says her and the kids won’t know how to instruct her around the house. I do t think it’ll be a problem, but I see her point. Thoughts?
