On the National Geographic channel tonight, Scott and I  watched a program about dogsand the science behind them.
!http://images.fabulously40.com/uploadedimage/9527/thumbx320/bulldog-pup.jpg!The program explores the history of strict, controlled breeding of specific breeds of dog. In some cases, the dogs were bred to purify the genetic coding (much like computer code!). In other instances, the certain breeds of dogs are cross-bred with other breeds in an effort to combine strong, helpful traits such as sense of smell, speed, ease of learning, etc.

They demonstrated a small, hybrid breed of dogs that have the ability to identify 12 different chemicals used in making bombs. They had been bred for their size and sense of smell, and never failed a test. They were amazing!

However, the bloodlines have become so isolated that any recessive genetic flaws are much more pronounced. Like aggression (pit bulls) and nervous conditions (much like humans!). Skin conditions, tumors and deafness are all flaws that specific breeds are known for.

This coin definitely has two sides. Are they weighted evenly, in your opinion? As is often wondered about other practices like this, are the benefits worth the risks?

    • I had an Australian Cattle Dog. She was amazing. This breed ranks in the top three in intelligence. But I know that this dog has been cultivated throughout the years by crossbreeding various breeds together for their characteristics. Some of them worked, some of them didn’t.

      I think that whatever breeders do, it’s their responsibility to be humane about it. I hate reading about puppy mills and some of the horrible injustices done when animals are used as a tool for some human purpose.

    • If one has any knowledge of how the AKC defines “breeds“, you are informed that genetic selective breeding is at the basis of all AKC accepted breeds.

      I am going to walk the fence on this as to whether this should be done or not....facts are, it is. Given that, I do agree with animal science that benefits us humans emotionally as well as reactively. As in any mutation, operation, drug or other treatment....side effects are a given, and usually a necessary component of advancing the science.

      With dogs, if those who “do not make the cut” are placed in loving homes....then I agree with the practice. If they are “destroyed” if not born with the correct genetic disposition, I am not in support.

    • I watched this a while back or something similar. It’s amazing how they have mixed and matched to create a specific breed.

    • Ok my PSA for the day. lol

      I think when we cross breed and try to changge is when the problems arise. My hubby had a pit, i have had many friends with pits, and they were the best dogs ever. It is in their breeding and their training.  

      Just like saying dobies turn, my friend had a dobies her whole life. Not one ever went mean and/or turned on her or anyone.

      I had an austrailian shepard, he was my love. Only me...he would go after anyone getting to close to me. The vet said if had been human he would have been classified a paraniod psycho. ohhhh I had him for 13 years and he had to be put down when he went after my son at 4 yrs old. It was the first time i could not stop him. I held him when they gave him the meds and he let me know it was ok. It was the first and only time he licked me on the face. ok enough...tears...

      Did i ramble...it’s the merlot lol

      What a cute puppy, though!

    • Very interesting. I don’t have an opinion at this time. I would have liked to have seen this program.
