You could advertise your dog as: 

AST I-III    - Almost Schutzhund Trained 
    (" ...Oh, Nico? He's a I, and we're working towards his II!") 

WHB I-III    - Wish He could Bite 
    (" well, he scored 21 in the bite last week, but the helper jammed him...") 
    ( * this one's neat - it's SO similar to a WH!) 

HCJ I-III    - He Can Jump 
    ( fails tracking, won't retrieve, but HE CAN JUMP! ) 

TLT I-V      - Tracks Like a Train 
    ( using a weight scale attached to the tracking line, determine how many pounds of pull the dog exerts while tracking (balls and food are allowed on the track) - multiply by the dog's body weight, add 2 (for Gene  England) and there you have it. (Use higher numbers if necessary, but I  thru V are most impressive.)) 

V1 thru V20   - Very good looking dog 
    ( depends on how you feel today. V1 indicates you think he's EXCEPTIONALLY good looking today, V10 and so on, he might need a bath, or grooming. If you rate him V20, he's probably in the sh*thouse.) 

SG1 thru SG20  - Saw Gene 
    ( this one describes in which order Gene worked your dog at his last seminar. SG1 indicates he Saw Gene first; ie; before any other dog. You COULD use SG20 (legally) if there were less than 20 dogs at the seminar, but you left your dog at home.) 

VB             - Very Beautiful 
    ( generally for the bitches, indicates you believe wholeheartedly in the show quality appearance of your dog. Your opinion need not be shared by any judges, or anyone else, as long as YOU believe it.) 

TLT            - Too Lazy to Train 
    ( this applies to both the dog and the handler. It's a valid title for anyone who needs a little something extra after the dog's name, and hasn't yet done anything about it. Very popular with Rottweilers and Shilohs over 140 pounds.) 

TDT            - Too Dumb to Train 
    ( also applies to the dog and handler. Used frequently when the handler can't seem to get his message across to the dog. Very rarely seen with the REAL working breeds - and never with a GSD.) 

RTO I-III      - Refuses To Out 
    ( super advertising gambit. Goes exceptionally well with " Are you man enough to own a Fido puppy? " type sales pitch. Really determined owners will brag how NO man in the US can get the dog to out.) 

WBA I-xx       - We Bred (him/her) Anyway 
    ( this one's for the owner who's a little lazy about training, ADs,KoerKlasses, Schutzhund degrees, and all that stuff. It indicates how many times the dog has been bred anyway. Very popular stud dogs can brag WBAs in the 20-40 range. Use Roman numerals, as they look much more impressive.) 

RH= Rodent Harasser (works for squirrly-men, bunnies >>they're really lagamorphs.. but I won't tell, coons, possums, skunks) If the dog is *really* good= RHX (Rodent Harasser Excellent) This would be for the dog that doesn't need a vet or a tomato juice bath afterwards... 

CP= Car protector. 

SS= Seat Saver.... for the dog that takes your spot on the couch & saves it until you return 

RD= Recycling Dog.  A dog that sorts through garbage would qualify... as would a dog that eats table scraps... so would a dog who plays with empty milkjugs or a dog that shreds paper. I think the RD would use a I, II & III  for the more "advanced" dogs. Does not apply for the dogs that recycle organic materials in the yard. 
  
FD- Flashlight Dog 
PC- Playground Certified... certified not to poop in a playground while anyone is watching. Can do varying levels- PC1 described above, PC2= will only poop in an inobtrusive spot, PC3= will not poop there at all- I save it for the neighbor's yard 

CBPD- Coulda been a police dog if I really wanted to, but I hate blue uniforms and hats. 
  
CP - Couch Potato, the most coverted award 
 
  

GCAP - Garbage Can Alien Protector for the dog that makes sure your trash cn does not contain alien life forms.. No trash hits the ground. The dog is silent but deadly in its pursuit. 

These titles are not meant to minimize the work done by others... 

The Shepherd is truly a breed that should be worked - balance often means a title at both ends.
