>>I have a puppy, labrador retriever. I was told that the sire had english in him and the dame was an american lab. Anyway, all the puppies from that litter have had eye problems and joint problems (dwarfism). I have been told that when you breed an english lab with an american lab, those are the usual problems that occur. My puppy and another puppy have had retinal detachments, and two of the other puppy from the same litter are completely blind. Also another puppy I have heard is not growing, she is 7 months old and she ways around 30 pounds. I have seen the papers on the pedigrees, checked everything out, etc. I was just wondering if anyone has ever heard of this happening, especially in breeding english labs with american labs. Please let me know something. Thanks!

Okay, I see your question now. I didn't answer it before because it will take an expert in Labrador Retriever genetics to figure out what went wrong with this litter. It is not as simple as breeding an American dog to a British one--that is done all the time and has contributed to some outstanding bloodlines. You would NOT usually get these problems from that mating.
When dogs are bred to other dogs who are far outside their bloodline, it brings in genetic diversity with the potential of improving the health and intelligence of the pups. Breeders try to do this every so many generations. I have Belgian Tervuren (I am not a breeder) and three of the four Tervs I've had have been outcrosses. One was American/French from a mating done in France, one was American/Belgian with a dog from Belgium imported to the US, and one was imported from Canada where her parents were of two different varieties.
Along with the potential for improving health and intelligence comes the risk of getting into some genetics in the outcross mating that will mesh wrong between the two mates. It sounds like that happened here. Sometimes there is absolutely no way the breeder could have predicted it. It's also possible something happened to the mother dog or the pups when they were very young, such as an illness like herpes or brucellosis.
The breeder should be willing to arrange for you to have another puppy at some point in the future in compensation for this happening. That is a typical thing that a responsible breeder will do when a puppy turns out with such a serious problem and others in the litter similarly affected.
