100 Years of Breeding Ruined These 10 Popular Dog Breeds

Bull Terrier:

Science and Dogs

Science and Dogs

One hundred years ago, the Bull Terrier was quite different in appearance from today’s breed standard. Muscular and athletic, but slender at the waist, with a flat, wide, gently sloping skull, Bull Terriers were the embodiment of agility, grace, and determination, and were considered one of the easiest breeds to train and control.

Today’s Bull Terrier has a very distinct egg-shaped head and a thicker, no longer slender, abdomen. They commonly suffer from musculoskeletal issues like patellar luxation, heart and allergy complications, and, most commonly, compulsive behaviors.

    Double merle is NOT lethal! It can cause deafness and blindness, but no other “serious health issues” are attributed to the coat pattern. It is wrong to breed merle to merle, but do not pass on myths and misinformation!

    Sadly, they didn’t include what they have done to the Collie either. It is shameful as they only slightly resemble what they are meant to be!

    You didn’t even mention the catastrophic health problems of Goldens and Dobermans. Once Victorian ideas of racial purity led to the concept of ‘pure breeds’ and closed breeding books, all current registered pure breeds became inevitably doomed to genetic collapse due the mathematical certainty of loss of genetic diversity. Drastically selective breeding that created such disasters as the modern English Bulldog hasten the process, but the overall result is determined by principles of population genetics discovered almost a hundred years ago. It doesn’t matter how many dogs there are in a breed if they are all essentially cousins.

    We’ve got a Dogue de Bordeaux..and thankfully they’ve not changed much since the 1800s revival of the breed.

    I have raised, trained and shown Shetland Sheepdogs for more than 40 years and the breed has improved immensely. When I first started it was very common for shelties to spin and twirl on a leash and spook at every loud sound. We have bred away from that kind of temperament and the modern sheltie is friendly and stable. Health testing for the “problems” you mention have removed those problems from the breed in general but we keep testing to make sure they don’t come back. The same problems can occur in shelter mixed breed dogs but nobody tests them. Double merles have always been around and are NOT the creation of modern breeding. Quite the contrary – blue to blue breedings that can result in a double merle are seldom EVER done anymore. I would strongly suggest anyone interested in a sheltie check out the website of our parent club – the American Shetland Sheepdog Association (ASSA) for the TRUTH about our beautiful breed and not believe the half-baked outdated ideas in this article

    I had a beautiful German Shepherd of the old kind. This was over 30 years ago. He was very fast, smart, loyal, agile, great health, and ran like a greyhound. I do not care for any of these new unattractive versions. I live in a high end neighborhood that is full of these new breeds. I dare say most are very unattractive to down right ugly. Unfortunately, the changes match the owners obsessions with small upturned noses, over blown cheekbones, and other new deformations that do not match the classic beauties. I suggest everyone visit the shelters for some beautiful dogs and cats and show them what real beauty is.

    Sharpei. Look up the original. Bone Mouth Sharpei. Todays are mostly known with out their true tile which is Meat Mouth Sharpei. The original came from China, a Long time ago. The breeding has given them skin allergies, along with sight issues due to the amount of skin on their face. More skin more sight issues. The original Bone Mouth was like a Hot Rod , compared to the Meat Mouth, which is more like a Bulldozer. I have my second one. He has the Bone Mouth head but the Meat Mouth body. Nice looking Bulldozer.

    Of the 200 dogs we have assisted with “loaner” wheel chairs through Red Flyer, The Handicapped Pets Community – FB, 85 are represented by these 10 breeds or approximately 43%.
