A Breeding Question (?)
 

:aimeeyork:animal-pa I study and ask, study and ask. I do know you have to inbreed, linebreed, outbreeding, so on to keep a purebred and for traits and so on. Here is the thing.... I was reading a book and it was talking bad about line-breeding (says it should not be done ; so goes in-breeding). I do know its ok to do. However you must mix it up also. My question is what breeding methods do you use? Like I said I want to keep it a full blooded yorkie blood line going....

Only the VERY experienced breeders should even attempt this. And this means knowing every dog in both pedigrees and knowing they all have cleared any problems that afflict that breed. To say it can backfire on a breeder is a understatement. It takes so much research on the bloodlines of the dogs you are considering. Remember, you can double up on recessive genes and end up with a litter with major problems.
You don't need to do inbreeding to keep a Yorkie bloodline. You can do a lot of research on a male AKC dog to breed with a non relative female and keep the Yorkie bloodline. You want to better the breed. Example, if you have a female with a slight fault you want to look for a male that doesn't have the fault but rather closest to the standard. If you breed to a male with the same fault what kind of pups will turn out. Most with the same fault as the parents.

Thank you! Like I said I heard bad things about this!

Good post!

Are you using both mryashgal and Snugscoleman as member names?

More important than learning about inbreeding, line breeding, outbreeding and such.... is to make sure you start with a male and female that meet the Yorkshire Standard! Go through the standard step by step and compare your prospective breeders. Have someone experience with AKC shows evaluate your yorkies. Have your vet evaluate too (although they seem to think any healthy two dogs can mate -- but at least they will check the female for any birthing problems).

They need to be more than just cute yorkeis. You are trying to better the breed, so you do not want to breed dogs that are not up to the standard. They may have a slight fault, finding a perfect yorkie is hard to do. But you need to compensate for that with the other mate, as Chantal was saying. For instance, if you have a male that is perfect except for larger sized ears (like mine), you look for a female that has tiny well-set ears. That worked well for me and two litters of pups seem to be growing into adulthood with nicely sized ears! They need to be free (tested) from disease and genetic problems. Their health history to include several generations back, should be thoroughly checked for the same. Make sure puppies are not being born with hereditary problems.

I would not even think about inbreeding and linebreeding without the mentorship of a breeder that has years of experience, and is thoroughly educated on yorkshire genetics. Too easy to make a misstep that will cause birth defects. Maybe not even with the first generation, but maybe the next. When you sell your puppies, you want to make sure you are not selling any surprises to their owners. Stick with unrelated dogs.
Post pics of your prospective breeders in the breeder talk forum. There are highly experienced and gifted breeders that will be more than happy to evaluate them. Try to get a good frontal and full body side shot. This would just be a preliminary assessment as to fully decide if they are breeding material, you would want to show them inaction to see how they mov and how their perosnalities shine.

So much to think about! It is commendable that you are researching this now. How long have you been breeding Yorkies?

No, you don't "have to." Inbreeding should NEVER be done and line breeding should only be something done by VERY EXPERIENCED and breeders with a superior knowledge of canine genetics. Linebreeding is merely an option, not something absolutely neccessary for any and every breeding program. In many cases, it's an "easy way out" for smaller, BYBs who really have no clue what they are doing.:thumbdown

Anytime someone asks about linebreeding, the question that comes to mind is, what are you trying to achieve that you believe only linebreeding will accomplish. If you don't have an answer for that, then it's not something that should even be crossing your mind.

Keep in mind breeding two unrelated yorkies can also bring in unknown genetic problems too. Breeding yorkies is not breeding pheno type to pheno type. Most breeder/exhibitors line breed, however you must know where the cut off is and where it turns into inbreeding. Only the very experienced breeders inbreed, it's the fastest way to set type, but it can also backfire and bring out those problems fast too. In other there is no short cut. One must study and I don't mean reading books. Take some classes/seminars, etc. Even with repeat breedings each litter is different, it's just how the genes shake up. Whether showing or breeding never breed anything with more than 3 faults.

My daughter has her own... she did not sign out so I just used it at that time.....

Thanks!
 

Thank you! I thought so on all above but not 100% sure ya know... we breed a collie yrs. ago (turned out great). My passion however are yorkies!
