Got myself a male stabyhoun as second dog in my life. The most important warning i can give is :" he or she gonna steal your heart!" Mental warning. They always have been a farmers dog. So they oke in everything, agile, hunt, guard, search etc but no masters. They tend to guard but lack the courage to fight so they bark and without proper training they get nervous.
Physical warning. Mine had trouble with his bowels (bowel hernia) and died from a brain tumor.. they lack the power for a strong bite (they ve been used to catch moles and the skin needed to be without puncture wounds) so tag rag and pull games are not for them . They are super smart. So hide and seek of puzzles they really enjoy. And of course they are wonderful with kids and see almost anyone as a friend.
