Inbreeding???
 

Hi All!


Was wondering if anyone here could help clarify something for me.

A couple of the breeders I looked at have bred half siblings both having the same sire. Since I've noticed it, it seems more and more prevalent... or maybe I'm just more aware lol
Now, is this considered inbreeding? And is it common in the yorkie world??
I've read that inbreeding can lead to a number of problems including health, disposition, etc.
Anyone have any experience with this? I know keeping lines "pure" is difficult due to a limited gene pool, but I don't want to set myself up for a baby with issues

Thank you in advance!

Years ago, I went to an AKC seminar on Line Breeding, and it was explained that line breeding can be a useful tool to set the good things in a line, but can also bring out the bad things, very bad things! Only a knowledgeable breeder should attempt. When line breeding, you need to know your genetics, your flaws, your health background, and what you are trying to accomplish.
NEVER should son be bred to mother. Sons get their x chromosome from his mother. Breeding basically the same chromosome.
I would say, be careful who is doing the breeding, and why.

This should ONLY be done by very knowledgable breeders, that know the pedigrees of the dogs they are breeding for many, many generations back...... There are breeders that do this with absolutely amazing results, but when a breeder does not know their own limitations, and they think this is easy to do, they are setting themselves and their breeding program up for catastrophic results. As stated above, you magnify all the wonderful traits, but you also magnify the bad things too, so the line must be "clean". This takes years of studying pedigrees and lines and who throws a propensity to exactly what flaws. All our Yorkies have flaws, and you breed these flaws down or out, by breeding dogs where one is much stronger in an area....you can breed out bad coats, size, any number of faults and flaws...but when a breeder that does not know what they are doing, starts playing around with indescriminate breeding and genetics, you can end up with tragic genetic results. I am sooooo envious of those breeders, magnificent breeders, that have the wealth of knowledge that enables them to purify a line and CONSISTANTLY produce healthy, genetically sound, gorgeous Championship dogs. It is a magnificent, hard learned skill that is not to be underestimated or unappreciated! (When one completely understands exactly what goes into keeping a Yorkie looking like a Yorkie, and keeping genetic anomolies out of a line by knowing pedigrees better than you know your own name, then one can better appreciate and understand how breeders can look at all the byb and indescriminate, irresponsible, "ooopps breedings", and get so angry and discouraged....)

Thank you both for such great replies! This should be in the library!

Laddy is a product of inbreeding. His Sire was bred to the dam of his creation. We love our precious Laddy don't get me wrong but he does have his issues. Severe separation anxiety for one. Very hyper, and very nervous. When nervous he tends to chew out his coat. I would be very leary of buying a dog so closely bred. If we had known then what we found out later we probably would not of gotten him. But with that being said would not trade him for the world. He is a very special little man.

Line breeding must be left to the people that know how to do it correctly....in the knowledgable hands of breeders that know what they are doing, the results are magnificent.

Wonderfully explained!

True. That's the reason I raised an eyebrow when I read that Huddersfield Ben was a product of a mother/son pairing. :eek:

Just to put this out there....line breeding is a little different than in-breeding!! Line breeding is breeding with the same lines and is different than a dam and son breeding, sire to daughter or half siblings that is in-breeding! Line breeding is breeding like to a grandparent or great grand parent! Or like ex....Durrer line to another Durrer line but doesn't have a close relationship upfront, does that make sense?

Thanks Donna for coming back and hitting on that...everytime I started to write, I was intending to point that very thing out, but then my mind diverted and I forgot! Thanks! I was going to give examples of how we look at pedigrees....how I study my pedigrees, so I do not get doubling up and triple-ing up anywhere close! I do not line breed and I want to avoid any super concentrations/close generations of the same dogs on any of my pups!.... I WISH I knew enough to do it fearlessly and accurately and magnificently.....maybe some day!

I prefer line breeding to set type and outcross only when necessary!

Hi Donna, good to see you again! Hope that you have been well.

HI GAIL!! It's good to see you :). I've been hanging in there! Still trying to get the show bug back! It's being a slow process but almost have Rusty finished!

I prefer line breeding as well. When you have common ancestors with excellent qualities and they were known to produce quality offspring, you are going to concentrate the genes for those characteristics and are more likely to produce puppies with those excellent qualities. However, if the common ancestors were just "okay" in type or possessed some qualities you don't like, then you are just as likely to concentrate the "bad" genes too so you do have to be careful. You also need to feel confident about the health of lines when you choose to line breed.

Inbreeding can set type even faster but, as already stated, it's not something just anyone should attempt
