Is aggression/protection typical for GSD?
Hi everyone. I just introduced myself into the introduction area but I will fill you in if you didn't see. We are adopting a 9 month old GSD next week who was bred and trained (just basic training) by the lady in my city who trains dogs for the sheriff and police department. We met him and spent 5 hours with him, and observed him acting very AWESOME around kids (including my 2 year old) and even him acting playful around other dogs. This all took place at a public park so he did not know the kids or other dogs.
When I told my family what breed of dog we were adopting, they immediatly began warning us of aggression and protective issues common with GSD. He seems like such a sweet/loving/fun dog that its hard for me to imagine him acting aggressive based on what I observed. My family member told me their GSD was this way as a pup, but did develop aggression after a year old.
What should I expect?
