hi all i wonder if anyone can help me. I bred my dog with a stud dog at the end of week 2 then a week later a scruffy mongrel got at her as well, is there any chance the mongrel could be the father ?

It's certainly possible that some of the puppies could be a result of the mismating. The only way to tell will be to get a DNA sample from your bitch and the correct sire, then have the puppies' DNA compared to them to see which puppies are by which sire. The purebred ones can be registered, but of course not the others!

ok thanks for that much appreciated, will my vet do the dna testing?

You can get the swabs here, no need for the vet to do it (This is where it would go anyway ;) )  It's just a mouth swab, you follow the instructions and send it/them off with the payment ;)

Hope this helps

i would love to know the outcome, lease keep us unformed

So do you end up with half and half? Like half the litter purebred and half the litter mixed? or would it all be one sort?
and can you only tell which is purebred or mixed by swab as Im guessing you would get half the puppies look like mum and dad and the other half look like the mongrol cross the mum.

It could be a single puppy sired by one dog and the rest by the other, or any combination.

Our family dog when I was a child was a mongrel which was the only one in the litter sired by a labrador, with the rest of the litter sired by a collie. Sometimes you can tell by looks, but not always.

Thats very intresting...
As I always imagined that if a bitch had 2 sires to her litter for example one was a collie and the other a lab, you would get half or however many that look like labs and then the rest would look like Collies! :-D Thats a big childhood imagination for you lol
Seems swabs are the only way!

Remember it is the same as with any species one sperm to each egg (apart from twins etc) no other sperm can enter the egg once it has been impregnated so no matter how many dad's or sperm flying around, only one will impregnate. I would think that the pedigree stud will have impregnated most if not all of the eggs already, with a two week difference, it is only if there were a late egg/s still there that the mongrel will have impregnated one.

It is best to be safe than sorry, so a DNA check should be done - you never know, but I would think that the poster should have all pedigree pups there. ;-)

If you read it again you will see it was a one week difference :) the first mating taking place at 2 weeks into the season. So if that has been too  early for ovulation then the resulting pups could actually be all crossbreeds aswell. As has been advised DNA testing is the only way to go.

Absolutely, Gillian. In fact, for a dog to seek her out and for an uncontrolled mating to take place (rather than her telling him very clearly to sling his hook), then I would expect the later mating to be more likely to be the right time and the crossbred litter more likely to materialise.

a few year ago I know of a flatcoat that was mated by a deerhound......the pups were very obviously deehound X but a mating had taken place with a pure F/C.  the litter resulted with pure & X

If you read it again you will see it was a one week difference :-)

Whoops! Absolutely correct, that will make a huge difference to the outcome. :-)

Aargh, how frustrating. I'd love to hear how the DNA testing goes.

Hi, sorry if this sounds dumb but if some puppies were sired by the first mating and some sired by the secound mating, a week later, would this mean the bitch would give birth twice? as some would be a week older than the others? how would that work, i am not a breeder, just curious, or would they all be born together but some premature? I really hope the puppies and your bitch are all ok, and the sire is the stud dog not the mongrel.

If the bitch didn't ovulate at the right time for all her eggs to have been fertilised before the other dog got to her, then there may be a mix of both dogs' sperm waiting to fertilize the eggs  (sperm from a really fit healthy dog may live up to 7 days) which would mean that all the eggs would be fertilised around the same time and the pups would be born at the same time ;)

Hope this helps :)

It's happened to me!  I had a Yorkshire Terrier girl, to be mated to a Yorkshire Terrier boy.  When she was ready, she actually crouched on the ground, to give access to a Chihuahua Long Coat boy.  The Yorkie mated her the following day.  She whelped one Yorkshire terrier bitch.  And SIX pups to the Chi boy, 3 bitches, 3 dogs.  She's obviously a proper little tart.

hi thanks to all who help shed some light on this situation, my bitch has now had her litter 1 dog and four bitches - all healthy.
they were all born on the 63rd day from the first breeding and 59 days after the second breeding what are your predictions now? stud dog or mongrel?

depends on what they look like, they could be sired by both one pup mongrel others stud dog, dna testing can tell you

As has been said before either or both  only way to tell for sure is DNA. 63 days is taken as an dogs period of gestation but it is only a rough guide as each dog, whelping is different. Some go early, some go late and a few read the books and go to the dates :)

have you asked your vet? maybe they could help.  I would have been most upset if that had happened with my bitch.  I made sure I was with her 24/7 after she was mated.
I got enough stick from my post on here a couple of weeks ago, anyone would have thought i had committed a murder with some of the replies I got.
Good luck

Reminds me of friends, who took their cross bred lab to the vet for first injections.  The vet looked - said "no, you're wrong, this is definitely a labrador puppy - nice lines too - what makes you say its a cross?"   "Because the mother is a German shepherd" !!!!!

(This was 30 years ago)

db what does this thread have to do with yours?? yours was about not wanting to give the stud owner a dog, this is about an accidentally caught bitch. this poster did not deliberately breed to both, his bitch was deliberately stood then caught by another dog and given the deliberate breeding he did not want to lose a litter of potential pure bred pups by terminating, i don't understand your point.

to Lokis mum! Can't wait to hear the outcome if and when the op gets the puppies tested. :-)
