Recently, a study was published with commentary stating that a dog's breed had nothing to do with its temperament. That is such a dangerous statement on so many levels. So a border collie who is high energy and motivated to herd and spin and bow, All By Nature, not nurture, has natural ...tendencies that were bred into it for hundreds or even thousands of years. A Basenji does not bark but rather yodels oh, so can we all teach our dogs to yodel instead of barking? A German Shepherd has been bred for hundreds and hundreds of years to be a protector and guard dog, and there can be some that are so gentle and magical, but for the most part, they are very sharp and smart and quick to react. Perhaps a very tightly wrapped dog breed is not the best choice for a family with toddlers? What do you think? Every Rhodesian Ridgeback I've ever seen, loves to lay on the couch, go through your legs, doesn't bark a whole lot, hates its toenails done, and thinks it knows better than its owner does although that probably is true very often LOL. Beagles tend to bark more than a Shiba Inu, and Golden Retrievers tend to be more gentle, much more gentle, than a Cane Corso. To even begin to say that breed does not impact personality or traits of a breed, is to say that we should remove all the groups from dog shows and not group hounds with hounds, or working dogs with working dogs, or herding dogs with herding dogs etcetera. This is absolutely ludicrous to claim that dogs or any type of animal selectively chosen for traits that become a breed over hundreds or thousands of years, have no differences at all. So apparently, a Chihuahua is a super confident 50 lb dog and a golden retriever is a super confident 50 lb dog, and a Tibetan Mastiff is a super confident 50 lb dog, and a Maltese is a super confident 50 lb dog and an Italian greyhound is a super confident 50 lb dog. It is so absolutely ridiculous. The same way that breeds of horses have different traits, longevity, speed and endurance, that showcase the differences between a thoroughbred, a Standardbred, a quarter horse, a Reining Horse, a roping horse, a Lipizzan and an Arabian just to mention a few, and let's throw in a little Connemara Pony just for laughs and giggles, are we to believe that Secretariat, or pretty much any Thoroughbred could not outrun a Shetland pony and that a standardbred who paces or trots and is actually disqualified if it crosses the finish line cantering or galloping, is just expressing its individual personality? The commentary on this article is quite dangerous. It is dangerous because it is misinforming people. It is dangerous because it is ridiculous to think that there are no differences between breeds. Every breeder of grand champion show dogs, or field dogs or greyhounds or thoroughbred race horses, will disagree vehemently that breeding doesn't matter. The breed is one of the most important factors in choosing a dog for one's family, for the show ring, for hiking or agility, for lure coursing, for hunting, for herding, for working, for Iditarod, for lounging on the couch, for being lazy, or for being hyper. It is everything. It does not mean that there cannot be individuals who are very atypical for the breed or breeds of which they are comprised. But what it does mean, is that traits selected for hundreds or thousands of years, by experts in that breed, have continued to be selected for and that becomes a trait that does define the breeds. I guess we need to all just cancel the AKC Meet the Breeds days and we should just say, hey guys come meet these four-legged mammals. They're all the same. Just ridiculous. Love your dog because it is your dog. But choose your future dog with intelligence and planning and forethought. Do not assume that you can purchase a Presa Canario and turn it into a Cavalier King Charles Spaniel. Do not purchase a Hound if you don't like to occasionally or more than occasionally hear howling. And by all means do not purchase a Great Dane if you're looking for a 10 lb toy poodle. They call them Great Danes for a reason. Not tiny Danes. Choose wisely our friends!
