inbreeding Inbreeding is not for novices...linebreeding is my preference and you know I have been around the dog kennel a "few" years ! LOL
The best way to find any genetic faults and fatal genetic problems is to inbreed. Brother/sister breedings, even half bro/sis is never necessaryIMO to produce quality dogs. There are plenty of fine lines for a novice to bred with, why take chances that can produce serious genetic problems, you can get those with outcrossing and linebreeding..don't ask for them.
Anyone who encourages you to inbreed a healthy line, does not have the potential litters best interests at heart...theyare asking you to take a chance on ruining a good thing.
When you learn what you are doing genetically, then a granddaughter, grandfather is a goog combination at times..if a litter is an OUTCROSS, then going back heavy into one of the lines is good, father/daughter is possible...but since you asked the question.."what is inbreeding", you are years away from attempting it. JMO
A responsible breeder must accept the good with the bad. It can mean a litter of genetically defective pups you must care for the rest of their lifes..you did it, you fix it!
You cannot sell them off to some poor unsuspecting buyer and wash your hand of it...plus, not all genetic problems show up in the early pup ages.
