Hello, Mihas, you wrote: M>>> Me the formal moment interests. The aforementioned exception to the rules concerns breed or to the specific individual who at present are in the service? SK>> it is formal, to the specific individual (appropriate breeds), transited a course, being near to and under control of the master (on a lead but as a muzzle and it is not mandatory). M> And thus, to this specific trained individual the requirement to be on service is not shown? For example, to be a police dog and to participate in patrol. No. There is Enough requirement on breeds. Now 100 % of dogs - are specially selected. At the auxiliary breeds including on adequacy to environmental conditions. If the guard dog behaves not adequately, it practically does not have chances to give descendants and to transfer the defective gene of "disobedience". At decorative dogs opposite, 99 % of selection go on the basis of an exterior, on it beautifully looking doggie can carry in itself ANY surprise, can on a pillow to the master, bite off a nose eye ears, be written in , gnaw furniture, tear up sofas, destroy footwear, yelp to bite and thus it is mandatory "tie" (and you thought why "factory owners" hold dogs in cells, in country nurseries, far away from eyes of potential buyers?) . By all means "tie", that there were beautiful descendants, with such form of a curl of a tail which can be sold EXPENSIVELY. And on complaints of owners of puppies always it is possible "you be not able to bring up dogs". And still a heap of money for and if it does not turn out all the same the master "late is guilty addressed", "spoiled". M> I.e. any citizen can get a dog of certain breed, to train and easy to walk without a lead and a muzzle? Correctly so: Any citizen wishing to get a dog of ANY breed, SHOULD will be trained itself, then to transit course together with a dog, and AFTER can easy walk. (Some breeds, after the additional expanded course, it is possible without a muzzle and sometimes without a lead).
