I agree with a GSD breed. if your considering this breed do yourself a favor and make sure you research reputable breeders and linage. it will also help if you where to visit a schutzhund park and talk with owners and breeders. DON'T just go pick out a GSD(not to say you can't get lucky that way)make sure you research the bloodline, also it will help if you look for german working lines not show lines(not that there's nothing wrong with show lines)Most important when you've found the right one for yourself and family from looking at parents ,bloodline and all pertaining factors, you have to stay on top of this breed. As soon as you arrive home with your new family addition you have?need to set order(training and discipline are a must). you will need to spend as much free time as you can with this breed otherwise your instore for a migraine.
