With or without pedigree ..? (en)

Until very recently, the jack russell could have no pedigree: then, why should interest us a piece of paper "that will probably increase the price of the puppy, if we do not care to go on display? We do, however, two considerations: instead identifies the pedigree of purebred dog. If until now you could call any jack russell terrier short leg (also of dubious origin), there is now a standard that includes specific characteristics, and can no longer be "cheating", a jack russell undocumented (although it looks beautiful) can no longer be defined jack russell, which means he can not participate in any official dog show and also meet with serious difficulties in finding a partner. Dog owners recognized, for the good of the race,

do not mate with more subjects without a pedigree, because even the puppies there are none (as opposed to what some believe, that there is not enough to have only one parent) and have a lower value. In addition, the coupling of non-recognition does not carry the start of a real selection of characters physically and mentally, which will have as its purpose the establishment of the best features and thus should be the goal of every true lover of the breed.

For these reasons, having to choose a puppy now, you should move towards the sons of dogs recognized, and then with pedigree.
Remains possible, even for some time to get the pedigree of the dog into adulthood (after 9 months) has freight in national and international exposure in which the judge issues the certificate of typicality. But why risk it if we want a jack russell doc?

Better to take a puppy whose parents have already been recognized, and therefore undoubtedly typical. [Adapted from "The Jack Russell Terrier" by G. Bauchal and R. Vincent ]
