Can you breed a CKC registered dog with another CKC registered dog that are related?

you CAN. sometimes it causes problems tho just like human inbreeding.

incest is not best

Not that I know of...not a good idea @ all to breed related animals or anything else !!!

it depends, how are they related? parent and child? sibling from same litter? siblings from different litters? distant relatives? etcyou might want to contact the CKC to see if the offspring can be registered since they are "inbred"

You can, but you cannot have the offspring from that litter or any litter after CKC registered. Generally it is not recommended by vet's.

One would have to know what the relationship was. Line breeding has been going on forever. It is best not to breed siblings but an aunt or cousin is fine.

Some like line breeding. You can add to the breed standerds that way if the line is meeting them. I would only do it once bro sis and no more you will also get some that are not at all what you want study youre line that youre dogs are form and see what you are passing on

First of all, Dogs that are inbred don't come out "retarded". Only someone inexperienced would say this. Dogs naturally inbreed with there own families to create strong lines and keep there packs going. Human inbreed dogs for the same reason. For breeders, it is a useful way of fixing traits in a breed - the pedigrees of some exhibition dogs show that many of their forebears are closely related. For example, there is a famous cat by the name of Fan Tee Cee (shown in the 1960s and 1970s) appeared in more and more Siamese pedigrees, sometimes several times in a single pedigree, as breeders were anxious to make their lines more typey. Superb specimens are always much sought after for stud services or offspring (unless they have already been neutered!) having won the approval of show judges. This leads people to inbreeding traits within a lines. However, inbreeding holds potential problems. The limited genepool caused by continued inbreeding means that deleterious genes become widespread and the breed loses vigor. Laboratory animal suppliers depend on this to create uniform strains of animal which are immuno-depressed or breed true for a particular disorder e.g. epilepsy. Similarly, a controlled amount of inbreeding can be used to fix desirable traits in farm livestock e.g. milk yield, lean/fat ratios, rate of growth etc. So in all honesty, it can go either way depending on what your intentions are. If you have a superb stud and a great bitch., who are related and the lines within your dogs are weak, check vigorously to make sure there are no underlying medical problems. Two dogs from the same litter are not recommended because if they have the same underlying disease this gene is more likely to develop in offspring.
