In/line breeding????
 

Ok, I may end up starting a very bad thread, but I really need to have an answer to question for someone who just called me, knowing that I used to breed yorkies. Needless to say, I didn't know the answer. So, I feel bad for starting this. I had someone call me that has a female yorkie that they were breeding with male yorkie not related to the female at all. She let the female outside after about 2 hours of trying to get the male and female together. She let the male out also. But she also let out the female's son, not thinking anything of it. She said before she knew it, the son was locked into the female. She said it couldn't have been but 1 minute that she turned her back. Is here anything for her to worry about? It's never happened before and this will be the female's 4th litter. This would've been the 2nd time that the other male (not related) would've been connected this heat. I think she said they were connected about 5 days ago. I'm concerned for her and have tried to do some searching on the net for her, but not really finding much. Thought my friends on yorkie talk could help. Again, I'm not doing this to start any arguments. So, please, if responses are made, just respect others' opinions. Thank you and God bless!

This is inbreeding (the breeding of close relatives). If the other male also got to her this season, then she'll have to have the pups DNA tested to determine who the father is (definitely if these dogs are AKC or she won't be able to register the litter).

Line breeding will be breeding of distant relatives...cousins, uncles/aunts, etc.

What happened was an accident, I'm sure, but an accident that shouldn't have happened. Anyway, hope that this helps.

*edited to add* there is a chance for problems since the genes are closely related. That's why only seasoned breeders should even attempt an inbreeding.

Sorry I dont know an answer but wanted to say I am very sorry this happened to her and I am sure she is stressing.....Things happen fast and even the best eye can miss it sometimes...

:yeahthat:

I'm not the expert on this but I know that you might get a less heated answer in the breeding section.

Good luck for your friend.

If the breeder doesn't know its lines well, inbreeding and linebreeding is a very bad idea. If there is any history of genetic problems at all in the pedigree of the mother, there will be a higher chance of the puppies having the problem since the mother and son mated.

The son got half the mother's genes and half the fathers genes. Since mother and son mated, those resulting puppies will have 3/4 the mothers genes and 1/4 the genes of its grandfather (the sons father). So therefor, more chance of genetic problems if there is any history at all in the pedigree of the mother.

Only breeders that REALLY know what they're doing should attempt inbreeding. They have to have a lot of experience and knowledge of genetics and know the history of their dogs' pedigrees several generations back. They have to know that there is no history of genetic problems and know what specific trait they are looking to breed for.

It's a mistake - it happened....you'll either have healthy puppies or you won't. I for one wouldn't buy an inbred puppy from someone who didn't know what they were doing. Too many risks...

I had a coworker whose two pittbulls bred recently (brother and sister from the same litter) and almost all the puppies died a couple days after birth. They just weren't healthy.

What you have described is inbreeding, not good at all.

You are so correct about inline breeding! It can be done but you must know the history of your two dogs..... good luck, hope all comes out okay and you have healthy beautiful puppies.... FULL Brother & Sisister Always A No, No!

Thank you!
 

Thank you so much for letting me know this info. I will definately let her know what to watch for. Hopefully she'll call me when the puppies are born and I can go over there and see for myself to make sure everything is ok. I pray that God will keep these puppies healthy and that nothing will happen. I know the one male was AKC, so maybe that'll help. I just don't know. Again, thank you all!
