Absolutely not recommended!
Most breeds of dogs carry some form of genetic problem.
They are too numerous to mention but can range from epilepsy to eye problems, spinal and joint deformities, breathing difficulties, temperament problems, heart disease, deafness and so on.
Experienced, reputable breeders who are aware of the problems in their particular breed do what they can to avoid passing on these problems to the next generation of dogs.
They do not use dogs they know carry the genes which cause the problems and they screen their own adult dogs before they breed from them.
Breeders will study pedigrees and use good quality dogs who have common ancestry going back several generations in order to, hopefully, produce healthy puppies of a particular type.
Breeding closely related animals greatly increases the possibility of producing puppies with genetic problems and no breeder with any common sense would even think about it.
P.S. In the UK, In-breeding is defined as closely related - mother/son, brother/sister, father/daughter and is NOT recommended.
Out-breeding is where there are no common ancestors in the available pedigrees. This is O.K. but doesn't help to establish a particular 'type' as you don't know what the mating will produce.
Line-breeding is where there is common ancestry a few generations back. For example a stud dog's great grand-sire could be a well-known and successful Champion and the b**ch may have the same Champion in her pedigree (say her grand-sire). Breeding from these two might just increase the possibility of producing a pup with the same attributes and quality of the ancestor.
If only it was that easy!

Maybe. Do you know all the dogs for the last few generations in the pedigree and whether there was any health problems? Do you know the littermates of these dogs and whether there was any health problems? Have the dogs in the pedigree had all appropriate health clearances? If you can't say yes, I do, and there are no health problems, then NO, you cannot do a breeding this close!
Just because you can't see a health problem does NOT mean that the dog is not a carrier for it.
Danielle - "It is a misconception that Breeding closely related animals increases the possibility that any bad genes in a line will show up. It does not 'cause' genetic disease."
What do you think is the likelyhood that someone asking questions here would have spent the hours needed studying the pedigree and dogs in it? What do you think is the likelyhood that someone asking questions on here has a clean pedigree?
A breeding this close does not "cause" genetic disease, but it SURE as hell will bring out every bad thing that there is! Of course it increases the possibility that you will be doubling up! Have you taken ANY genetics classes?
Yeah, breeders DO this, but NOT with a pet with an unknown pedigree!
And brother X sister is NOT linebreeding, it is much closer than that.

Breeding that close should only be done by the most knowledgeable of breeders. I would point out that there is an entire breed (Llewellin Setters) that owes it's existence to the breeding of littermates. So yes it is possible, but the average person would be off their rocker to ever attempt it.
Where both the advantage and disadvantage of inbreeding is the doubling up of recessive genes causing them to become dominant genes. So both a dogs strengths and faults will show up in the litter normally resulting in the need for "culling" (not a pleasant experience)

One of the most hotly talked about topics with regard to pure-bred dogs is the use of in-breeding. This is a term that is often misused and is extremely misunderstood.
Part of the misunderstandings come from differences in the way the terms are used within the scientific/medical field, and how it is commonly used by breeders. These are the most commonly accepted definitions used by serious dog breeders and will be the definitions used within this article.
In-breeding - This is the breeding of closely related animals. Brother-Sister, Parent-Offspring, ½ brother - ½ Sister.
It is a misconception that Breeding closely related animals increases the possibility that any bad genes in a line will show up. It does not 'cause' genetic disease.
the advantage of In-breeding is more likely to help "set" or "fix" a particular trait within a breed or a line by narrowing the gene pool to favor those traits. So if a breeder is looking to set a particular desirable feature of their line then in-breeding and choosing the offspring most strongly possessing that trait can be beneficial.
In-breeding can also help identify those bad genes that exist within a line. Dogs possessing the bad genes can be eliminated from a breeding program and carriers also identified.
Intermittent in-breeding within a line or breed is not damaging to the long term health of the animals. However, in-breeding over successive generations can lead to reduced fitness and fertility problems among the offspring, resulting in a phenomena known as In-breeding Depression. It can take many generations to show up depending on the traits involved.
To use this method responsibly a breeder would not want to in-breed on animals with known genetic disorders, temperaments not in keeping with it's given breed, or known serious structural faults, or to in-breed frequently even on healthy-superior specimens.
According to geneticists. Line-breeding can be carried on for many many generations without deleterious effects on the line or breed as long as the individuals involved have few hidden genetic disorders.
Hope this helps

No, you should not breed two animals with the same family blood. This is just like humans when there is incest.
This will cause deformities, whether they be physical, or mental.
I would not recommend doing this as it causes many problems in animals especially if the offspring breed with each other again or with another dog not of their blood.

The answer is Yes! as sad as it may seem! some breeders do this as i have just recently descovered myself! its sick! and the dog will surely end up with a big hormonal problem! which will affect the dogs mental sate of mind! (go crazy)& whats the reason for them doing this i wonder?!...is it for them selfs! of course it is! its carnt be for the dog!half of them dont want to pay stud fees, i think so they just call in the brother or who ever, the other half want to perfect the best looking dog for `Show` purpuse! We can only guess at why thay do it! or mybe someone out their know the real truth! but what ever the reason, i personal think its wrong! beacuse thay will still turn around and sell you the dog for whom will most diffentaly have some sort of behaveral problems! you only need to read the news to know what that could intail!! check your pedigree! if its not clear ask the breeder to go through it with you! if in doubt not buy!

Yes it is genetically possible but the question is, would the dogs agree to it? siblings of the same litter can recognize each other even when they are adults and I think that they would probably not. Breeding so close in a family line causes some difficulties and weaknesses in a show dog and the AKC (American kennel club) would probably not allow it since a breeder would have more sucess by mating siblings in the show ring

hi i will attempt to make this easy. Breeding siblings will often convey out the wonderful genetic characteristics, and the worst genetic characteristics interior the offspring. this variety of breeding might desire to basically be tried with the aid of experienced breeders who've carried out lots examine, and all available sorting out, to make certain the wonderful result. those breeders are very selective of their lines, and basically try this to larger the breed. For those attempting this because of the fact they only have a male & female dogs, the outcomes could be disastrous. it incredibly is particularily actual for brother & sister, because of the fact the genes are so heavily matched. it incredibly is virtually without exception that any responsible breeder might use brother & sister, until attempting to keep a species it incredibly is virtually extinct.

Its the same as a human brother or sister having a baby. The offspring will come out with mental or physical abnormalities. In some cases the babies could end up crazy!
