Great Dane In-breeding!?

Question

My two Great Dane siblings has bred, what could be the possible physical effects of this on the pups? Could it be larger? What are the other pros and cons?

Answer 1

I can see absolutely NO pros for this.

The major cons would be that ALL the genetic defects that are in the family line, have a significantly higher chance of coming out in the pups.

I would have the pups aborted while you are having her spayed.

Answer 2

Whatever is in the background will be doubled up..that means the good and the bad. If there is hip dysplasia, heart issues, thyroid, etc then it will bring it forward and will likely have an effect on the puppies.
Understand that while not ideal IF this breeding was undertaken by someone knowledgable, with an understanding of genetics and knowing everything in the pedigree it would bring forth good things and strengthen the line, however done randomly it can have negative results.

Answer 3

Inbreeding and linebreeding are both fairly common in the professional dog-breeding world, but they should NOT be done by an inexperienced person and certainly not by an accidental breeding. Usually inbreeding is done to isolate a particular desired trait, but there are a lot of risks of genetic problems appearing in the puppies. Even if they don't show any serious physical deformity or illness, they could be mentally disabled, making them hard to train, unstable, or even aggressive. They could also just be more susceptible to future problems, like cancers or problems with the joints. Some inbred puppies are perfectly healthy, but it is still very risky.

If you want to keep the puppies, you should talk to a vet about how to prepare the mother to give birth and how to care for the puppies when they are born. You should also get the male neutered right away so he doesn't try to breed again soon after the puppies are born. It is really hard to take care of a pregnant dog and even harder to take care of puppies. It is also very expensive, with special foods, vet visits, etc. The only people who make profits selling puppies are those who treat their breeding dogs very badly and don't care for the puppies very well.

If you don't want to keep the pups, you should get the female spayed right away. The vet will remove the uterus and the puppies, so it is both an abortion and preventing future pregnancy. Even if you do keep the pups, you should get her spayed after the puppies are weaned.

If you don't have the money to spay and neuter, talk to your local humane society. Many humane societies have reduced cost spaying and neutering available for people who can't afford it normally.

Answer 4

Line breeding is more common than inbreeding. If you don't want the puppies then you could have her quickly aborted by an injection. If too much time has passed you will have to decide if you want to keep the female intact or not. If you do want to breed her at some time in the future, then you will have to continue the pregnancy. Your puppies do not have the optimum genetic ideal, but they aren't going to end up with 6 heads and 4 ears from this either. But if there is a genetic defect within the line, it can be intensified by inbreeding. Honestly, it will probably turn out ok, but there are more risks than with an unrelated mating.
Good luck.

Answer 5

I can only assume the reason these siblings weren't spay/neutered was because you were planning or are showing these dogs. Regardless....what's done is done. I'm not going to get on my soap box and read you the riot act...you are concerned so after doing research I've found a site that best describes the downside to inbreeding and it also explains line breeding (breeding with relatives) which is similar to inbreeding.

Answer 6

Have the pups been born or not?

There is a greater chance of them getting recessive traits that would have been bred out otherwise.

We'll say that this trait is albinism, for shits and giggles. Neither dog is albino, but it was a trait dominated by another.

Well, if a dog has a recessive albinism trait, his gene is Aa. A normal dog is AA, and an albino is aa.

Now, if the male dog is Aa and the female dog is Aa, then there is a 25% chance of a normal dog without the recessive, a 50% chance of a dog with the recessive, and a 25% chance of the dog being albino.

Basically, it increases risk and such. It's not just albinism and conditions like it, either. There could be family-common diseases or conditions.

There are no pros unless you're absolutely breeding for a trait, and it is very risky.

Answer 7

Why you want to do such a tight-breeding for? Although the pups look okay outside, but all the genetic defects will appear inside of the dog. How would you feel if someone wants you to mate with your sister? Of course you won't do it.

Answer 8

How irresponsible it is for you to have left your dogs to mate when they are related.You can end up with pups that have defects to many to mention.I am appalled that you are so casual about what has happened, people like you are give breeders a bad name..

Answer 9

Tons of genetic defects are possible- even if they are not apparent at birth. If the female hasn't had the pups yet (and is sounded like the breeding just occured) please have her spayed ASAP. = Neuter the male while you're at it... They will both be happier and healthier for it, and you won't have any more "in breeding scares"

Answer 10

there could be very bad physical effects from this;

you should get your dog an abortion and spay her before she breeds with her brother again.
