Evaluating Shelter GSD?
I'm new to the forum, but not to GSDs, having previously found/adopted a byb GSD with multiple temperament issues (separation anxiety, and similar, but nothing big). Turned out to be a great dog with a little work. He died happy at 13+.
I may be in position to consider a shelter GSD. What kinds of tests can I do in that limited environment to suss out behavioral issues? I know the shelter wouldn't offer him unless he passed some minimal testing, but I'd like to focus our time together on evaluating him for typical GSD issues to determine how big a project he might be. I understand even a good GSD may be aloof and untrusting during an initial interview, so I need to dig a little deeper than that.
Thanks for any help.
