If done correctly line breeding, with proper testing done you should have no issues, now with that said if you are tightly line breeding and there are thryoid problems etc you are increasing you odds of it popping up by 2-4 times that is why testing is important. The problem with BYB dogs are that they dont do testing on their stock, they are too lazy aka cheap to have it done it cuts down on their profits if you have to shell out for the testing. BYB dont know the back ground on their dogs. THey dont know what is in their pedigree generations back. BYB are far more dangerous than "Hobby/show" breeders. We atleast if some trait does pop up can pin point to where it came from and not re-peat the same mistakes. But I digress back to the line breeding we do it to keep certain lines, you dont want to just pick random jo-smoe dog to mate to because if you dont know how it will outcross with your dog you can end up producing some funny looking shelties....and thats not what breeding is about producing some random puppies, breeding is to improve the standard.
nope, low thyroid is the only tip of the iceberg... improving phenotype by line breeding does NOTHING good for genotype, at the best it still keeps those recessive genes from doubling up... while low thyroid, hip displasia and VW are being checked what about immune problems that keep cropping up like various allergies, various growth even benigh ones, cancerous tumors, diabetes and all those wonderful heart murmurs, pulmonary effusions, epilepsy, hernia and what about depression?????
Dr Pitcairn in his book "Natural health for dogs and cats" states that he noticed overall deterioration in pets health since he graduated from vet school in 1965. He also states we now seeing very young animals with same kind of diseases that we used to see in very old animals. It seems that accumulation of poor health is being passed on with each step. Sure not everything is because of inbreeding. Lots of it has to do with environmental
changes, commercial food and general free use with antibiotics, steroids and such.... In our obedience class 3 dogs out of 16 had to drop out for health reasons and all of them were under 1 year old! 2 of the dogs had very serious health problems and one will return to next class...
