Selection within the family is the key.

Guy Ormistion article in this month’s Coonhound Bloodlines. “Here’s the Key to the gate. The scheme needed to improve what you have in hound abilities is the judicious outcross. The outcross is a cross of relatively unrelated dogs within the same breed. To reiterate: inbreeding is a means to keep the excellence you have, while outcrossing is your only method to improve your bloodline.
Well I sure disagree and I am sure many do agree with his method which I still do not quite understand. Someone tell me where I am going wrong?

Inbreeding of itself has no bad effects. This was proven most definitely by Dr. Helen Dean King at the Wister Institute in Philadelphia. She bred rats, brother to sister, for over a hundred generations. The result was that the rats were larger, lived longer and produced larger litters than did the rats with which she began her experiments. The reason for these good results is that careful selection was practiced during the entire experiment. All undesirable animals were not bred. Only the best animals were kept for breeding. If a given line of dogs carries an undesirable gene, it must be eliminated or it will continue to appear in future generations.
Inbreeding accompanied with careful selection is one of the best possible means of breed improvement. Slight inbreeding practiced by most dog breeders and serves to maintain stock uniformity and keep the children similar to parents and general ancestry.
Linebreeding, a form of inbreeding, unfortunately, has been over-publicized, and depending on who you talk to - is either the answer for all that is wrong, or is blamed for everything from temperament to health problems. It's neither. As with inbreeding, the results obtained depend entirely of the quality of the original stock, the skill with which the breeding program was planned and executed, and on the methods and amount of selection.

I agree breeding can be 100 percent harmless and improve.strength and purity within a bloodline. however the negative effects of inbreeding comes from the doubling of a harmful receive trait. in the case of humans an example would be tay Sachs disease rr genotype I think. commonly around the world you see communities inter marrying in order to preserve their line trouble comes in rare circumstances but when they donuts extremely dramatic such as.extreme degenerative diseases. so I agree interbreeding would be determined by your original stock. sorry if that was a bunch of jibber jabber
