No, NEVER. And I worked for a GSD handler at one time, they NEVER trimmed whiskers.
Bunny has no front dew claws. Her breeder (NOT Julia/von Sontausen, Bunny was a stud fee puppy) removed them. I didn't even know until I went to clip nails and there was just a bump where the nail should be. Grabbed my cell phone and called Julia and said "They took off her dew claws!" There was several seconds of stunned silence followed by "YOU'RE *BLEEPING* ME!" Neither of us ever THOUGHT that an experienced breeder would remove front dew claws?! Bunny (a red sable) has a dark spot where each dew claw should be, so she was about 11 weeks old before we noticed.
