The Ellendonk Kennel produced MANY outstanding working (and show/sieger) dobermann.  Their foundation bitch, Dixie v.Krakau (brown) won the D.V.Meisterschaft in 1964 and was dam to two D.V. Meisterschaft winner (Gerra & Imo v.Ellendonk)! 
Their most famous dobermann was BINGO v. ELLENDONK.  Bingo is credited with improving the character of the dobermann in Europe.  He won the D.V. Meisterschaft (1977) at 2 years of age and many other schutzhund trials (& the only dobermann to score 100/100/100 in schutzhund).  Of course he passed the koerung for life with highest ratings for hardness & working drives.
In the words of Ottmar Vogel: "Bingo, at the age of 2, had by 1977 already become D.V. Leistungssieger and has since than an unbroken succession where he has rarely been knocked out of anything less than second place.  This dog was titled SchH.3 over 30 times and always achieved victory through consistant work.  He was taken to numerous FCI European Master trials and constantly impressed everyone with his enormous fighting drive and his steady and strong nerves." 

Bingo v. Ellendonk is the son of Jago v. Beelen & Palma v. Ellendonk.
Jago (brown) won the Bundessieger title, Dutch Champion & D.V Sieger.  He also passed the koerung for life with highest rating for hardness and working drives.. 
Palma (black)won the D.V.Meisterschaft (1975) and passed the koerung for life with highest rating for hardness & working drives.  Palma is Dixie v. Krakau granddaughter.
Bingo was born in 1975.  He was the only male (black).  He had 2 brown sisters (Barka & Bora).

He was also a German show Champion. 
MUSE v. Kirchbuhl  passed the koerung and competed in the D.V. Meisterschaft.

Out of the breeding  with the Leistungsruden "Astor v.d. SchmimmelSchulzHeide" SchH3 (much-titled with the DV Leistungsprufungen) came the Leistungssieger of 1966 {Winner of the D.V. Meisterschaft} Gerra v. Ellendonk and the Leistungsrude, Gero v. Ellendonk." (SchH3 brown).   Both dogs strengthened (or consolidated)  the Leistungsposition {working trial reputation}of this line and consistently were rated excellent. 
 "Gerra" was then bred with BDSG Arugus v. Neroberg SchH3.  Out of this important (noteworthy)  "J-litter" came some very beautiful and very good working dogs; such as: Jenny v.. Ellendonk (brown, SchH3, often V1 rated in conformation; the foundation bitch of the Kennel  v. d. Rauberhohle, Owner: Gero Muller of Goppingen. 
Out of the "i litter" the BDSG Iris v. Ellendonk (brown, SchH1) should be mentioned, as her breeding with Miko v. Furstenfeld (black SchH1) came the D.V. Leistungssieger {winner of the D.V.Meisterschaft} of  1975,  "Palma v. Ellendonk" (Black SchH. 3 )..  The D.V.  Leistungssieger {winner of the D.V.Meisterschaft} of  1971,  Immo v. Ellendonk (Brown, SchH3), was not used for breeding. 

Many good workingdogs came out of the Von Ellendonk Kennel, that in the Nordrhein region, corrected  the poor (literally: tattered or battered)  working reputation of the breed. 
The Sauermann's also produced some beautiful Siegers such as BDSG (show champion) Kora v. Ellendonk, SchH1 (Argus v. Neroburg.& Gerra v. Ellendonk)      BDSG(show champion) Iris v. Ellendonk,  DVSG (show champion) blue Vesta v. Ellendonk SchH1 (Chico v. Forell & Jessy v. Ellendonk),  the DV Jugendsieger (youth show champion), Ulfas v. Ellendonk brown SchH1, Angekort (Gero v. Elendonk & Afra v. Honenstauf.),  the World youth Sieger, Xyla v. Ellendonk SchH1,Angekort. 
Other noteworthy Leistungsdogs (working trial dogs) were also Satan & Sanko v. Ellendonk, both angekort, {passed the German Koerung} and also the daughter of Sanko & Palma v. Ellendonk = Afra v. Ellendonk (Black SchH3, FH, Angekort for life)   The owner of the Kennel: v. Burg Homeim-Stein, H. Schauer Pegnitz, also often titled at Sieger trials, Trux v. Ellendonk,, multi titleholder DV Siegerprufungen {winner of many shows}. 
The best then and now DV Leistungssieger is  Bingo v. Ellendonk (Sire: Jago v. Beelen SchH1 brown, Angekort, BDSG, Int.Ch. -  Dam: DV LSTG. Angekort - Palma v. Ellendonk )  This dog at the age, of two had by 1977 already become  D.V. Leistungssieger {winner of the D.V.Meisterschaft = National SchH.Championships) and has since then, an unbroken succession where he has rarely been knocked out of anything less than second place.  This dog was titled SchH. 3 over 30 times and always achieved victory through consistent work.
He was taken to numerous European Masters trials of FCI and  constantly  impressed  everyone with his enormous fighting drive and his steady and strong nerves. 
In terms of breeding this dog is very interesting. One can say that his temperament traits are found on two sides - in his ancestry and in what it produced ("BluLinienplan").
One is very happy that he has already left a strong working mark on his progeny and hope that he continues to be intelligently  bred.
As is often the case, this dog of course, also had faults that, with particular matings, could become more pronounced.
As a model this dog should be valued as he has already received a conformation rating of Excellent. 
In terms of his utility, one should keep in mind  his somewhat poor stand  to the fore and his back, which is not quite solid. 
With his height of  68 cm, Bingo fits exactly into the medium size range.  It is of course, always difficult to maintain height.  Presently, we are unfortunately vacillating a little too much and we should try to stabilize the correct height for dogs at around 68 to 70 cm.  Too tall or too short will not meet our goal for building our working dog lines.
Bingo's first progeny were successes at the DV Siegerprufungen in 1980 and 1981. 
In 1980, the two year old "Hexe vom Wilden Markgraf" SchH 3, black,  ADPR, (Bingo v. Ellendonk,SchH 3 IPO 3, Ang.. FH & Bina v. Wilden Markgraf, SchH3 Ang.) earned twelfth place with 275 points (SG rating).and 
In 1981 Ilo v. Kirchbuhl. (black SchH.3 and son of Bingo Ellendonk and Cora v. Kirchbuhl) earned 276 points in the D.V. Siegerprufung  & also passed the Koerung), and also in 1981 the D.V. Leistungssiegerin {winner of 1981 & 1982 DV Meisterschaft} Cora v. Papenkamp SchH3 (Bingo v. Ellendonk & Afra v. Papenkamp).
Also interesting, is the fact that both dogs (Hexe and Cora) were similarly bred so that both have the Leistungsruden Falk v. Rotbachtal as a grandfather on their mother's side. Falk's Grandfather in turn, was the three-time Leistungssieger of 1961, 1962 & 1963 - Fred v.d. Blutenstadt Orsoi.   Here you can see with respect to their structure (formation) how such a line is built up (established). {illustrated in photos}
And now back to the Ellendonk Kennel.  After Gatin des Zuchters died, Mr. Sauermann also ended his active work with the dobermann. However, by  preserving, through more breedings, the valuable heritage of this Breeder, it is hoped to consolidate, strengthen and improve this foundation.
