true meaning of show ratings i.e. EZ an U ratings - Page 1

I was wondering if anyone can shed some light on the true meanings of the above ratings. I understand that some breeders opt for a vet certificate in order to get the dog off and get an EZ rating instead of a U rating. But when exactly do they resort to this trickery? Do they get a hint in the first day of the show that the dog wont place very high and therefore rather than accept a low rating they opt for the EZ option? And when exactly does a dog end up with a U rating , which presumably (i might be wrong here!) lowers the status of the dog further. Any clarifications/opinions on the true going ons would be helpful. Thanks

Dogs who get Ungenügend are dogs from owners who dont go to the Vet but dont show up after the stance when they think its too low, they cant bring the dog on a show in Germany for a half year. they who go to the Vet are for 99 % the same but dont get a 6 month ban

I got E.Z. with Pallo when he was injured in protection in '98. (Knocked out cold: horrid helper work) We did go to the official vet ($$) and pulled with his (and Messler's) recommendation (more $$) so there was no 6 mos. penalty, but my dog was so bruised that he couldn't compete in anything for months anyway. I have never been so down and disappointed in my life as I was that night. :((( SS

Slept in the campground with my arms around my aching dog, suitably soused on pitchers of good wishes from my friends, just happy Pallo had lived through that awful day. SS

A dogs reputation does not suffer by receiving U. No one notices. Being passed by many dogs is certainly more damageing. To withdraw is certainly unsportsmanlike, but is hardly different than avoiding shows where the competition is tough or attending all of the small shows and those with soft competition to rack up the V1 placeings.

I am sorry I am ignorant in show etiquette/rules and procedures, but does the handler/owner get a preliminary rating on the first day of the show? Does he then decide whether it's high enough to proceed to the 2nd day?
