like any dog a GSD will chase things, cars, animals, birds, etc.
when they're young you have to train and socialize them around
people and and other animals. when i got my pup i knew
we were going to be in the woods a lot and encountering
horses, joggers, dogs, etc. i made sure we spent a lot
of time around horses. when flocks of birds were along
the creeks bed i would walk my dog through them and all around.
i didn't want him chasing after birds, horses, people cars, etc
so i exposed him to all of these, almost daily.

when you have a dog you have to think ahead to stay
ahead. you want to stop bad behaviour before it starts.
