Wertmessziffer • DDR Rating System This is the best rating system ever put together in my opinion. With these numbers we can determine much about the dog without video or picture. Young dogs between one and two were evaluated using the ZTP or Zucht Tauchlichkeits Pruefung, like a Prelim test. Dogs over two were evaluated at the Koerung or approval process for entering the breeding program. Much like a license it had an expiration date, two years. It also could be fixed (final permanent) by the administrators after 3 tests and examinations by age five. Occasionally an exceptional dog was given the more permanent Kor after just two presentations to the committee. The system used number as follows: first number was body type. Second number was power/structure/constitution. Third number was body issues, such as low-station, hock issues or anything else. Fourth number was temperament. The fifth number was degree of sharpness (not to be confused with fear, but the thresholds before a dog exhibits aggression. So a dog with good nerves was not a sharp dog). The next number was the degree of courage and hardness: ability to take pressure.

Here's video on my channel where I discuss it to some degree: kzfaq.info/get/bejne/fKmpZr1n3ZjMfn0.htmlsi=h1UODkz_8JeIyJ3F

Thank you very much for your kind words.

Thanks for the comment and subscribing to my channel. Linebreeding in my opinion is not breeding in the immediate family, i.e; half siblings or full sibling mating, parent to child or grandparent to grand-child is inbreeding. By contrast, first cousin, second cousin and third cousin mating is linebreeding. Aunt to nephew or Uncle to Niece is also line breeding. The COI is a measure of risk. in half sibling mating, the Coefficient of relationship is 50% and the COI Is 12.5%. By moving the common ancestor one generation further back in time, to be a common grand-parent as opposed to parent, makes them first cousins and the COR is 25% and the COI is 6.25%. The question is what is the "sweet spot' between locking in desirable traits, versus locking in deleterious traits and disease. Many feel that anything above 6.25% is unsafe. So a 3% COI or a 5% is considered safe. An uncle to niece mating at 9.63% COI is pushing it. A half sibling mating at 12.5% is risky. So you have already accomplished pre-potency in the half sibling mating. I don't think you need to go further. In your specific example, you have a very high COI so i would outcross, or go back to a common relative far back in time, in the 5th generation, not closer. The outcross should have a similar phenotype to your current dogs, but be from a different genetic tree and should compliment your current dogs. The responsibility of breeders is to breed healthy dogs (free of hereditary diseases), with good temperament and good structure, therefore, when planning a cross, pedigrees provide useful information. So further inbreeding for its own sake is not useful further in your case.

Hi Kyle, play and prey drive and aggression and guarding insticts are indeed genotype expression, not phenotype. So breeding dogs that exhibit certain characteristics to each other, you'll get those characteristics in their offspring. Just like friendliness and a good full mouthed grip is also genetic. In herding sheep, a good genetic, calm grip is very important, to hold the sheep and not hurt it. This characteristic is also useful in police work, in holding down a suspect and not chewing him to pieces. You don't want the dog to maul somebody, but hold and apprehend. So genetic selection for a good grip was important, along with other characteristics. However, keep in mind that most genes are polygenetic traits, not single traits. In the GSD, color is a simple Punette square calculation of color genes. But behavioral characteristics is a complex combo of genes, not a single trait. Most genes are polygenetic.

My pleasure!

I loved my time on the NWA corso podcast. I have been invited back. Your questions are easiest to answer in a podcast

​@@VonGontaHaus yes sure it would be it took me 6 attempts to type it out to make it understandable, would be great to hear the answer on the future show with Joe

thank you for the compliment! It was a gorgeous, well structured litter, with very nice temperaments!

In 1907, Charles and Gertrude Davenport developed a model for the genetics of eye color. They suggested that brown eye color is always dominant over blue eye color. This would mean that two blue-eyed parents would always produce blue-eyed children, never ones with brown eyes. For most of the past 100 years, this version of eye color genetics has been taught in classrooms around the world. It’s one of the few genetic concepts that adults often recall from their high school or college biology classes. Unfortunately, this model is overly simplistic and incorrect - eye color is actually controlled by several genes, 8 of them. My example was a quick memory thing from my high school biology class, based on what I learned from this 1907 book. Brown is usually dominant over blue and this model of a single genes controlling color was taught in schools when teaching Punnette sqaure. I finished high school in 1985! So my memory is from something I learned almost 40 years ago. One gene, OCA2, controls nearly three-fourths of the blue-brown color spectrum. However, other genes can override the OCA2 instruction, albeit rarely. This multifactorial model for eye color explains most of the genetic factors that influence eye color. I suggest you google the answer, as my explanation was simply meant to show how dominant and recessive genes combined when a single gene is involved. We have since learned in humans, that 8 genes are actually involved.

The goal is to evaluate the dog in front of you and act accordingly. Regardless of lines, the individual puppy needs to be trained. Socializing is very, very critical in German Shepherds. Take him with you everywhere and expose to strange people, environments and surfaces. Leerburg has many good videos

If you are new to breeding, I don't advocate ANY form of inbreeding or line breeding. If you breed dogs with a propensity for heart disease, or cancer, to each other, even if you were not inbreeding, if you breed dogs with genetic predisposition to diseases, you will in fact, get diseases! The inbreeding didn't cause the diseases. You must choose the healthiest animals possible. I'm not advocating full brother to full sister mating. Half sibling mating, another form of inbreeding, is also too tight in my opinion. A 2-3 breeding can create pre-potency. (half uncle to niece). In other words, it's a grandchild of the same dog on one side, and a child of that very same dog on the other side. Genetic testing has to be done and only very good specimens need to be chosen. A dog of same phenotype to same phenotype can be bred without inbreeding as well. You can get a consistent litter by breeding phenotype alone, without genotype. For example, you breed two dogs that are black together that have heavy bone structure: same phenotype. This gives the illusion of a consistent litter, because both parents already start off looking similar, but this will not be a passable characteristic beyond that first litter. By contrast, let's say you start off with similar looking dogs that have a common grandfather, and you breed them together. Now you have both in play, phenotype and genotype. Pre-potency means that the allele pairs are doubled up in one parent (usually the father) and when he is bred to a completely unrelated female, even though technically both parents are 50%/50% of each child, the parent that has tight inbreeding, or loose inbreeding, his characteristics will outpower his partner and the puppies will look more like him, than like her. In other words, you pair an inbred dog or a line bred dog, to a dog with an open pedigree, his genes have been "concentrated" and thus, have a stronger influence over a non-inbred dog. That is what pre-potency means. But you are not just breeding pedigrees. You must selection test the dogs involved. So because some puppy is a grandchild of famous dog X, and another puppy is great-grand-child of famous dog X, and I pair them together, hoping to produce some qualities as dog X, guess what? If they themselves don't have his qualities, he will not be reproduced despite being a grandfather on both sides! .

She's well! Still cleaning up after her brood, but no milk, but they still try to nurse.

embarkvet has a test kit for 125 canine diseases, including epilepsy and DM. OFA hip and elbow X-rays are required. Some disease, like Degenerative Myelopathy are such that it only appears as a recessive trait, masked by a dominant gene. So if both partners are carriers, the offspring will definitely have this disease. Linebreeding and inbreeding doesn't cause bad genes. They are already there. But it exposes bad genes because a carrier of a recessive trait, that meets up another carrier, because you're increasing the allelic frequency of a certain ancestor's genes, will now allow for two carriers to meet up, which otherwise would not have met up and been masked by a dominant gene. Some diseases, like epilepsy, can lie hidden for 30 generations, and only show up many generations later. This was true for a long time for the German Shepherds bred in the United Kingdom in the 1930's-1950's. So certain countries are known to have certain lines of dogs with certain diseases. So you must choose the very best, healthiest dogs, where you know the ancestors as far back as possible before inbreeding. Some diseases appear to be connected to color genetics. For example, the spots on a Dalmation led to incidence of deafness and kidney disease. So we don't breed genes, just for color for instance. Genes are in clusters and other factors are involved, because you're breeding the total animal, not just a color gene. That's why an Irish Setter was mixed in with the Dalmation to fix the issue, but the issue is now back. In German Shepherds, when color gets faded and washed out, this is undesirable and Captain Stephanitz felt that faded color is a sign of genetic weakness. So when the border opened up, and the DDR dogs were available, breeding the sable, and pure black dogs to the West German dogs re-invogorated the gene pool and the dark sable dogs with the racoon eyes increased overall health and vitality in the breed that was getting bottle necked with the black and red dogs that we only saw. In the French Bulldog, some colors command higher prices from buyers, and people pay a lot of money for these colors. They are asking for serious problems from a breed that is already not a healthy breed in the first place. That's why breeders should never breed for color in order to command a higher market price point. That's not healthy for the breed. In general, if you inbreed, you must immediately out-cross, and then line breed in the next generation to a less related ancestor. If you line breed (as opposed to inbreed),it's safer, you don't need to outcross as often, until you reach a genetic bottleneck. Once you've locked some traits, you need to outcross. It has benefits, without which we wouldn't have the world's most beautiful horses, the cows that produce the most milk, the sheep that produce the most wool, but it has drawbacks. It's a tool to be used intelligently.

Taking care of a litter of puppies is pretty labor intensive if you do it right. Lack of sleep in first week as I feed via their mom around the clock

you are 100% correct. My friend Mike, shown in the video, is a professional dog trainer and has the experience to handle these smart dogs. I breed German Shepherds, and I recommend all protection/obedience people go to Mike if they are in the 5 Boroughs of New York. If they live in New Jersey, I train as well. My training website is: jerseycitycanine.com/
