reasons why u cant breed half sibling dogs?

Question

half brother and half sisters they have same sire but different mothers can u breed them, whats d reason, and effects, but they were registered, possible?

Answer 1

Only very experienced breeders should undertake this. Many show breeders will line breed to bring out a specific desirable trait. The only breedings that should ever occur are father/daughter or half-siblings, but only with knowledge and never repeatedly.

Answer 2

Well, it's not guaranteed to happen, but it is more likely to have genetic problems. This is because of genetic mutations.

Say you have a dog C from parents A and B, and parent B has a genetic mutation. This mutation might not show up in the resulting dog because of the good gene received from parent A. Now, say you have dog D, from parents A, and E. Dog D has the same genetic mutation, but it again doesn't show because of the good gene from parent E. Now you breed dog C and dog D. The resulting puppies could all have the genetic mutation carried by both dogs C and D because it is passed on twice, with a lower liklihood of good genes covering it up.

That is why. Any bad gene mutations, or other genetic problems are more likely to show up. This is why inbreeding is very bad.

Answer 3

Unless you have a REALLY good knowledge of genetics, disease inheritance, and the genetic family tree of the dogs involved you are likely to run into serious inherited health problems doing that.

Simplified version: All dogs (and people and every other living thing) carry recessive genes for inherited diseases. If two dogs are bred together that carry the same recessive gene, the disease will likely occur in some of the puppies. If you breed two dogs that are closely related, they are more likely to carry some genes that are the same, so you are more likely to get genetic diseases.

1.Not all dogs are built to be bred.

Most pets, although lovable, are not of breeding quality because they have genetic defects and other problems that should not be perpetuated. People who breed dogs for a living are very careful about choosing which dogs they will breed together based on physical characteristics and behavior. Some people decide that it would be fun to breed and just start looking for a dog that has the proper equipment and is willing. This can be a huge mistake.

2. There are already too many dogs in the world.

Breeding your pet is a serious endeavor and should not be taken lightly. There are far too many pets that end up in shelters without good homes. If your breed of dog has large litters, what will you do if you are unable to sell the puppies? Do you really want to contribute to the massive problem of pet overpopulation?

3. Dogs that aren’t neutered face serious health risks.

Consider your dog’s own health. Male dogs that are neutered are less likely to be hit by cars, because unaltered males have a very strong urge to roam and find a fertile female. Male dogs will go over or under fences, through doors and windows, and will pull leashes out of unsuspecting hands in quest of a mate.

Additionally, neutering greatly reduces the incidence of prostatic disease and eliminates testicular cancer in males, and cuts down on breast cancer in females. The possibility of uterine infections is also eliminated by spaying.

4. Female dogs used for breeding may have unwelcome visitors.

If you spay your dog, you will not have to chase persistent male dogs out of your yard. Also, you won’t have to worry about cleaning up messy heat cycles.

5. Be prepared to work like a dog when your pet goes into labor.

Many people do not realize just how much work and expense is involved with letting dogs have puppies. Getting the mother through pregnancy is the easy part, but labor is truly laborious for dog and owner alike. Dogs usually decide to have their puppies at the most inconvenient times, like 2:00 in the morning when veterinary hospitals are closed.

If your pet develops a problem during delivery, it means at least the expense of an emergency call. If the complications are life threatening, you must be prepared, especially if you have a breed of dog that has a broad head like a pug, to pay for an emergency C-section. It is very distressing to have to leave home in the middle of the night, worry about your pet, get a large veterinary bill and then try to explain to your boss why you cannot possibly come to work the next day.

6. It can be devastating when the puppies die.

There is always the prospect of the loss of some or all of the puppies. A neonatal mortality rate of 10 to 30 percent is considered normal. And, it’s easy to lose a puppy if you don’t have the experience or knowledge to care for newborns. Because puppies are not able to regulate their own body temperature initially, you may need to supplement their environment with heat.

7. Not all dogs make the best mothers.

If your female doesn’t have enough milk to feed all its puppies, or decides that feeding her offspring is not her cup of tea, it will be your responsibility to provide them with nutrition every three to four hours, round the clock. And how many mouths are there to feed?

Another aspect of puppy care that you can look forward to if your dog wants nothing to do with her brood is the manual stimulation of urination and defecation. Until puppies are three weeks old they will only void if directly stimulated. If mom isn’t doing this, you will need to take a moistened cotton ball and gently rub the urogenital area until the babes begin to urinate and pass stool. Failure to do this can result in some pretty unhappy puppies.

8. Good luck seeing a profit!

Your last responsibility before they go to a new home is to have them dewormed, vaccinated, and examined by a veterinarian. You will want to make sure that you have budgeted a sufficient amount for this purpose. Needless to say, if you decide to breed mixed breed puppies, you have no opportunity to recoup this expense.

Puppies are a lot of fun and it can be very exciting when they are born, but more often than not, owners find themselves in over their heads when they decide to endeavor into breeding.

Answer 5

The probelm is when you line breed or in breed you increse the risk of having more genetic problems.
Any time you breed closely realted blood lines you can bring out the best or worse qualities in the animals.
They may look great but if epsilpsy runs in the bloodline and you breed to closely you increse your risk of all the pups having it.
Why do it when there are many perfectly good studs and dams available to breed with.

Answer 6

You can breed half sibling such as this but if you want to register them it will be known by the breeders association. Most breeds or dogs are done exactly this way to get a line of specific characteristics in the animal. The risks are that you will breed dogs and lock in an undesirable problem such as diabetes, blindness or deformities thereby weakening the breed.

Answer 7

Bad idea - inbreeding, even if they are only half siblings, increases their likelihood of having genetic defects. The explanation why is long and complicated and requires understanding of genetics, but basically just don't do it!

Answer 8

it's perfectly possible if you want a pack of dogs with deformaties and genetic problems. can you support a whole pack of dogs with genitc problems?

Answer 9

i wouldn't do that because they may have defects (mentally or physically). Think about it would you want children with your half brother or sister??

Answer 10

There could be major health problems!
