Out of the 8 puppies produced in this imaginary example litter- about half of these, or 4 puppies will end up being damn near clones of the Sire. This is due to the doubling up of the genes of the dog that’s in the pedigree twice.
The remaining four puppies in the litter (again, this just an example of a typical inbreeding) may be born with issues.
DOUBLING UP ON TRAITS: BOTH POSITIVE & NEGATIVE
Remember, when inbreeding- you’re not just doubling up on the positive traits, you’re also multiplying negative traits.
So, while half of the puppies in the litter may be replicas of the Sire, the other half could have inherited two copies of any negative recessive, (or hidden) traits.
These can include but are not limited to: underbite, kinked tail, wry jaw, hydrocephalus, heart issues, murmurs and many more. The list could go on.
If the dog being used twice in the pedigree has any of these issues, or is even a "carrier" of any of issues (remember on a Father/Daughter inbreeding the puppies produced in that litter will carry 75% of the Studs DNA)
Any negative recessive traits (not just the positive) that the dogs carry (including some that as a breeder, you may not even be aware of) can surface.
For a breeder that’s solely interested in money- producing a few unhealthy puppies is no big deal. There are many breeders out there that couldn’t give two shits about the health of the dogs they produce.
But for true breeders- the real ones- that put the time in to study genetics, that do the health testing required to responsibly produce healthy liters, the ones who put in the hours to learn and hone their craft.. producing a puppy that has any health issues, defects, or is born with any type of pain or discomfort, can be devastating.
Breeders that truly care about the breed and about the puppies that they produce and sell- will only carry out an inbreeding after hours of research and completing genetic and health testing.
But, even after doing all of this and doing everything right… there is no guarantee that issues won’t be present. Again, genetics can be tricky and there are still issues that can pop up.
This is true with any breeding, not just with inbreeding or tight line breedings.
UPSIDE VS THE DOWNSIDE
When done correctly, the upside to an inbreeding is that offspring that are as good as the Sire (possibly better) could be the end result.
Additionally, dogs produced in inbred or tightly line bred litters (both males and females) typically produce more consistent litters.
This is due to the higher likelihood of passing on their traits to offspring over dogs with a scatter bred pedigrees.
Every one of the studs on our yard are either inbred or tightly line bred in order to produce the most consistent litters as possible for our Customers.
That’s just one of the reasons that so many people choose our Studs and also the reason they return for repeat business. They produce. Plain and simple.
Anyone arguing this fact either owns a Stud with a similar look and views ours as competition, isn’t a fan of the amount of business our Studs generate, or is unable/unwilling to pay our Stud’s fees.
Sometimes other breeders decide to go with cheaper options, dogs that carry a look similar to ours, but take a look at the productions vs our studs. They are not the same.
A tightly bred dog will always outproduce a scatter bred one, no matter how good the scatter bred Stud looks.
Now that you have a better understanding as to why we made the decision to carry out this type of breeding after having extensive testing done, fully understanding the risk involved (ones that most breeders don’t pay attention to, or know exist) We made the decision to carry out the breeding.
