I did a dual sired litter last year

Wow...I've never heard of such a thing (well, not on purpose, at least<g>.

Why did you want to do this? Just curious...

Would you do it again?

Thanks,

Is anybody aware of what institution keeps track of DNA Test in Europe. I have seen breeders websites who are located in Europe and under certain dogs of theirs, they made a notation of "DNA Tested".

I'm interested in finding out if someone gets a pup from said "DNA Tested" Sire and Dam, once the pup gets to the USA, is tattoed or microchipped, is DNA Tested and how do they verify that the pup is actually of these parents. There should be some kind of cross communication between these institutions even if the actual puppy owner is the mediator to insure progeny...NO?

It was on purpose :-) I did it for a variety of reasons, but mainly as a learning experience. What better way to compare the progeny of two stud dogs then a side by side blind study. I made educated guesses (I was only about 70% correct), but until the pups were 8 weeks old I did not know for sure who was sired by which dog. So my personal opinions on what I expected from each stud couldn't really come into play when evaluating the pups. I've compared different litters from the same dam and different sire, but you have to take into account environmental influences for each litter before and after birth and also just "selective memory" on the part of the breeder when the litters are a year apart :-)

I also like it because assuming the female does get pregnant by both males it's double the genetic contribution from her for only 1/2 the physical impact on her. Basically two litters for the price of one :-)

I'd definitely do it again in the right situation. It's not cheap, the DNA testing and other fees involved with AKC added about 500 to the overall cost of the litter, but it was worth it.

Thanks for the reply...very interesting!

Interesting point, I had not even considered that.

A friend of mine just did a dual sired litter with frozen semen. The repro vet is the one who recommended this, because one of the dogs was older when he was collected and his semen quality was not as good as she would have liked. So they did a frozen semen surgical implantation with the older dog semen and also with a younger male that had excellent semen quality.
she won't know which pups are sired by who until they are tested, so it's going to be fun to watch them grow up and try to figure it out!

The pups are due in about 2 weeks,I can't wait to meet them. I think it's a really great idea!
