a gsd can do everything a corgi can but a corgi cant do everything a gsd can. throw a frisbee for your dog to catch mid air and then turn to the corgi and say your turn! then throw a ball in the lake and when your dog brings it back turn and say your turn! now if your gsd cant do basic "big dog" things like that then i guess you'll have to accept all the jabs towards your dog. btw pretty dog!
no matter what kind of dog you have, nothing shuts up people quicker than a well trained dog.
