The first description of the breed was written in German. The phenotype (looks) of the dogs rather than the hunting application, became slowly more important in dictating the breed. The German Dachshund Club (Deutscher Teckelklub or DTK) was founded by Klaus Graf Hahn and Major Emil Ilgner in 1888. Two years later (1890) 54 shorthair Teckels were registered in the very first German pedigree book. These dogs could be considered as the foundation for the entire breed. It was not until 1925 that the official German breedstandard was published.
"Der Hund in seinen Haupt- und Nebenrassen", Dr. H.G. Reichenbach (1836) first described the breed's external characteristics close to the modern Dachshund or Teckel. Louis Ziegler praised in "Haarwild-Jagd und die Naturgeschichte der jagdbaren Säugethiere. Zur Belehrung und Unterhaltung für Jagdfreunde" (1848) the excellent nose and versatility of the Dachshund used in hunting. Ziegler also mentioned that due to its great nose, this courageous dog has very little problems to work on a leash as a blood tracking dog. He recommends also the use of the 'mongrels' of the Schweißhunde with the Dachshunds. Apparently at that time, the mixing of these 2 "breeds" already took place.
Johann Friedrich Freiherr von Fleming published "Der vollkommene teutsche Jäger", a book containing drawings of the "Tachs Kriecher" with crooked front legs and "Tachs Krieger" with straight legs, that exhibit more likeness. Von Fleming wrote these dogs were traling and chasing the game while giving tongue, indicating the hidden game with diligence and zeal to the hunter,which separates these dogs from other hunting dogs.
Carl von Heppe (1751) commented in his book "Aufrichtiger Lehrprinz oder Praktische Abhandlung von dem Leithund, als dem Fundament der edlen hirschgerechten Jägeren" that there are Dachshunds with long and short legs, and others with straight and with crooked legs like seen in the Leithunde. This underlined that in those days, dogs were not selected and classified on the basis of phenotype but according to similarities in traits or functions. There were no breeds as we know now.
German foresters who were in charge of maintaining the hunting grounds for the royalty, selected and bred the smallest and most tenacious Bracken to reduce the number of foxes and badgers in underground dens. The meat of small game that were prey to these predators were favored and at that time less expensive than beef or lamb. Prior to this period, there were drawings of small dogs
used in badger, fox and otter hunting, and even in hunting beavers for the medicinal castoreum (anal sac oil) but these dogs only show vague resemblance to today's Teckel.
