Dog Sires

[Bequia]

Can my dog sire a litter from an offspring of his own?

[wildwood]

Yes. This is the basis of line breeding to get certain characters into a breed.

For the laymen, this practice is not recommended as it most likely leads to health and temperament issues.

[lankeela]

Disagree on both counts, yes it can, but this is known as inbreeding rather than line breeding, which is where close relatives mate, rather than immediate family such as father/daughter brother sister. Only if the parents have health/temperament problems will they be passed on, if they are both healthy and of good temperament then reared correctly it is no more likely they will get problems that totally unrelated parents, who can in fact produce problems if they have them themselves. Many breed particularly imported ones were established by bringing in one male and two females, and the male would then be mated to his own daughters and so on, to produce a line from which the breed would become established. Even Golden Retrievers all stem from two dogs!

Gosh you talk a lot of rubbish lankeela.

You disagree but you say "Many breed particularly imported ones were established by bringing in one male and two females, and the male would then be mated to his own daughters and so on, to produce a line from which the breed would become established, exactly what I said.

Line breeding starts by intense inbreeding.

It's possible, but definitely NOT a good idea. Whether the parents are healthy or not, there's a higher chance of them producing an unhealthy pup (just as in people, it's not rocket science!)

In fact there are some pedigree breeds who have been so interbred, that even though there are thousands of it's breed out there, genetically speaking there are only a handful of 'individuals' - making them an endangered species.

I pointed out the difference between line breeding and in breeding - line breeding is not what is meant by close relatives as I said. Line breeding selects a mate from further back in the pedigree, often picking up the same dog several times.

There is no more chance of producing an unhealthy pup from inbreeding than there is of outcrossing, particularly if both outcrosses carry the same problem.

[lankeela]

Don't take my word for it.

Hi Lankeela. Either way, the original question regarded a dog siring one of its own litter. Which, by your definition if I interpret it correctly, is not line breeding.

To address the OP's original question, then no - not a good idea to do this.

[lankeela]

My intepretation of the question was whether it was physically possible for a dog to mate one of its own children, which of course it is, the same as it is for humans, but even less of a good idea (unless they are from Norfolk lol). Some people think because they are father/daughter brother/sister they will not mate - try telling the dogs that!
