Interesting article in a French canine magazine this month. It's about selection in breeds. There is a tremendous loss of genetic diversity in dog breeds.They studied 10 breeds over 6 generations and the loss of genetic diversity can reach 90%. There is "artificial "selection, restricted numbers of studs and bitches being used.
Closer to home:
Just take a look at how many dogs get used and re-used in the same year and often in the same country.
In some countries, a stud can be used up at age 2.
An Australian study, hardly 10% of the dog population will reproduce...
They also talk about illnesses...
Then, it is said that some " show-champions" can father up to 30% of SCC LOF registered dogs.
How some healthy dogs are never used and everyone runs to the "champions" is not a novelty. And we all know champions are not always the best dogs. Look at the Barbet.
It's always, of course, also a question of ethics.http://www.avarefuge76.com/_media/files/Selection_letat_des_lieux_alarmant_dresse_par_les_scientifiques_et_les_solutions_a_apporter.pdf
