Regarding the dentition of a Longhair, the Association Breeding Regulations (VFR) of the German Longhair Club states, "Longhairs that have missing teeth/teeth, an overbite, an underbite, or a crossbite shall not be bred with. (Double bindings are not considered defective)." Thus, where Longhairs with missing teeth may not be bred, on the other hand, Longhairs with double bonds (for example, regularly occurring: a double P1) may be bred. Missing teeth do not include teeth that have been removed for medical reasons, such as in old dogs. In the latter case, however, a statement from a veterinarian is necessary. So bring that statement with you when you come to an exterior inspection!
Teeth of a Longhair according to the FCI breed standard
The dentition of a German Longhair is described in the FCI breed standard (No. 117) as follows:
"Jaw/Teeth: Jaw not excessively fine. Complete, well-developed teeth with 42 teeth [and molars]. Upper incisors should close scissor-like over lower incisors."
Tooth formula:
3142
-- x 2 = 42
3143
The formula means regarding the teeth of a Longhair, that in the upper jaw there are (on both sides): 3 incisors, 1 canine, 4 premolars and 2 molars and in the lower jaw (on both sides): 3 incisors, 1 canine, 4 premolars and 3 molars. That adds up to: ((3+1+4+2) + (3+1+4+3)) x 2 = 42.
