Question about inbreeding...

[DorkyYorkies]

I don't know if this would be considered inbreeding or not...that's why I am asking!

I am looking at getting a smaller male from the breeder that I got my male (Scooter) from. My question is can I breed one of Scooter's puppies to Scooter's half sister's puppy? Scooter and his half sister have the same mother, but different fathers. Also, the father to Scooter's half sisters puppies is in no way related. I called AKC and they said to contact YTCA, but I could not get in touch with any breeders. I thought you all might know....

My husband breeds and raisings beagles for rabbit dogs. He has said it is called line breeding. He has bred a half brother and half sister before. He said it makes the traits more prononunced in the dogs. He's not home right now but I am almost certain that it is ok with the AKC. I mean all of his dogs are AKC registered so...I hope this helps...

I don't even think it would be considered line breeding...they would not even be half sister and half brother...the parents are just half sister and half brother.

It is called line breeding because the dam and sire have the same lines within their pedigrees. Scooter and his half sister have the same mother...their mother would be the grandmother of any puppies produced...regardless of which sire or dam was used.

Not only would traits be more pronounced so are faults.

I don't believe AKC gets involved in breeding practices which is why they probably referred you to the YTCA.

It would be considered line breeding:
Line-breeding - This is the breeding of animals that share common ancestors but are not closely related. For example the dogs may share a common great-grandparent.

So would this be bad to do or would it be ok?

Anytime you breed, whether it is line breeding, inbreeding or outcrossing, there are risks. Most people line breed if they are sure of their lines, know the weakness and strengths. With line breeding you are more likely to get consistency in type. If you have certain faults in your lines that need improvement then you would outcross to try and improve those faults. You would need to study the Yorkshire Terrier standard and honestly evaluate your breeding stock. First you have to start with sound stock, those that conform close to what the Yorkie standard outlines and then your try to improve your lines. An example would be if your Yorkie has improper coat, say cottony coat. You would not want to keep breeding cottony coats because that would not be improving your lines. You would want to breed to a silky coat. You would not want to breed dogs with common faults because that would just set those faults in your line.
Here is a little article that explains about the different types of breeding and the advantages and disadvantages of each:

Still line breeding.

[DorkyYorkies]

Do any of you have experience with line breeding? If so, what was the outcome?

[Ladyhawk]

The outcome of line breeding depends on the quality of the common ancester. If the grandparent that the dogs share in common is not an excellent representation of the breed of excellent health than you would be going backward. Doubling up will only produce as good as the dog that you are doubling. If the common ancester has LP for example your pups will now be twice as likely to have LP even if neither of it's parents have it.

Ok, so for example...if the grandmother is a larger sized floppy eared yorkie, would all of the puppies end up being large and floppy eared???

If both sire and dam had the larger sized floppy eared yorkie as a grandmother then some of the puppies could end up that way but you never know. Some could take after the grandmother and some may take after the father or grandfather. It has a lot to do with what genes are dominant and you really don't know what will happen.

[DorkyYorkies]

So really you could end up with any size yorkie regardless.
