IDENTIFICATION OF BREEDS

"Identification of individual dogs is possible on the basis of inherent and aquired markings, the possibility of error can never be excluded. Unmistakable indentification is possible on the basis of definition of blood groups respectively polymorphuous protien and enzyme systems (Schleger and Stur 1986), on the basis of DNA- fingerprints (Jeffreys and Morton1987 Georges et al., 1988) as well as with microchip identification (N.N.,1993)

Based on blood groups, polymorphuous protien- and enzyme systems as well as DNA -fingerprints respectively canine micro satellites, the verification of an indicated lineage of two specific parent dogs is possible in an individual dog (Morton et al., 1987; Binns et al., 1995; Fredholm and Wintero, 1996; ZAJC and Sampson, 1996).

Identification of a paticular breed affiliation is nevertheless only possible based on exterior markings which are defined in the breed standards, however in an individual case the undoubted affiliation of a dog to a breed is only partially possible.

Of course, based on canine DNA markers one can execute genealogical studies about the genetic distance between breeds or populations (Fredholm and Wintero, 1995; Okumara et al., 1996; Pihkanen et al., 1996; ZAJC et al., 1997) but affiliation of a single dog to a certain breed or the determination of lineage of a mixed breed dog of certain breeds based on canine markers is not possible according to current scientific standings (Templeton, 1990)." (Stur 2001)
