Can a dog get pregnant by two different dogs?

Yes

Absolutely!!!  You need to protect your bitch, from all entire males. If you have not and she has mated with one or more, I dare say you shall have a very mixed litter. :-(

And if you are hoping to register them with The Kennel Club, then they need DNA testing to confirm the sire.

are you a breeder or did this happen by accident how old is the bitch if she is too young i would abort the litter and as for registering them with the kennel club i dont know how it works over there but if all the dogs or even just one of the dogs was a different breed then you cant register them where i am they are just mutts then

how did it happen ?
was she out?
or does she live with the males?
what breeds are they?
how old?

The pups and the males that served ehr woudl need to be DNA tested and then the pups too so that their parentage coudl be established.  Those that were by males of the smae breed coudl be registered with the respective sires details,a dn any that were crosees of course couldn't be.

yeah but she isnt saying if all the dogs are the same breed if all the dogs are mutts or are purebreds but arnt the same breed as each other all you wind up with are mixed breds and therefore arnt purebreds in anyway by the sounds of it i dont think they would be the same it sounds like a couple of neighbourhood dogs got to her because if you were a breeder and took the dog to the stud home you would choose one particular male and then the stud dog owner( if they were responsible) would completely seperate the bitch and the chosen dog to a completely different area where any other males couldnt get to her this sounds like and accidental breeding with neighbourhood dogs because if this happened to me i would be raising hell with the stud dog owner and if it is the case of the stud dog owner having more than one stud and she/he didnt make sure your bitch only bred with the chosen one then they should be liable for the costs of dna testing if you this was a purpose breeding you should have a contract with the stud dog owner which would outline all circumstances such as something like this

It doesn't matter if any of them are mixed breed, if some are purebred and the parentage can be establised those particular pups can be registered no trouble.  If there is more than one purebred sire then those pusp can be registered with their correct siore.

For example the bitch mated with two males of her own breed and then to the mutt up the road.  6 pups born two from each sire, on testing the four that have sires of the bitches own breed (providding that they are registered and so is she), then the pups can be registered to the correct dogs, but of course the forms will need to be signed by the males owners (most likely in this sort of case though it is the breeders own males).

I suspect in this posters case that she either mated her bitch wityh an outside stud and on getting ehr home one of the own males mated her also, 9r perhaps the poster has two or more males that got to her in ehr season, or possibley either of the above and the bitch got out and mated with another dog.

yeah i understand what youmean about one of the males being the same breed as the bitch but what i was saying was if neither were the same breed then they would just be mixed bred dogs

How strange.I didnt know a dog could carry litters from more than one dog at one time.What an eye opener.

Just as a cat can be impregnated by several males, and carry kittens from different fathers, so can a bitch.

My neighbours cat was a bit of tart.  She sat on the fence "calling" to all and sundry!  She attracted attention from a black male, ginger and tabby too and they all took turns!  She had Seven kittens, two black, two tabby, two ginger and a tortosiseshell!  It was a very visual lesson of genetics in action!

(I never did work out where the tortoiseshell came from)

I know that chinchillas have two wombs and can get pregnant once and then again a few days/weeks later.They then have their kits within a matter of weeks apart.I have had that befor when i didnt seperate my two properly,they were in a breeding cage but the divider gave way and they mated.Thank god we are not like that .:)

All cats are tarts! ;) the meaning of the word Queen, as in breeding Queen (Quean originally) is hussy, wh*re or tart ;) :D 

My guess is that she was either a Black cat carrying Ginger (which is also genetically Tabby), which would then give Tortoiseshell and Ginger kittens when mated with the Ginger, and BrownTabby  or Ginger Tabby when mated with the Brown Tabby (Brown Tabby being dominant to Ginger tabby) also possibly Tabby Tortie (Tortoiseshell in tabby markings ;) )

or she was a Ginger (Tabby) cat, mated with the Black cat this could give Black, Ginger, Tabby (Black carrying Ginger/Tabby) and Tortoiseshell :D :D 

or if she was a Brown Tabby, mated with the Black she could have all the colours (Black is dominant to all of the other colours)  mated with the Ginger she could have Brown Tabby or Ginger (if she carried Ginger) and mated to another Brown Tabby she could have Brown Tabby or Ginger (Tabby) kittens (if they both carried Ginger).
With the combinations you've given the possiblilities are almost endless, especially as you don't know what's in the background ;)

Yup, cat genetics are great if you're interested in genetic inheritance :D :D :D 

>My guess is that she was either a Black cat carrying Ginger (which is also genetically Tabby)

Not quite Dill. :) RED CANNOT be carried as it is a dominant colour. Only dilutes can be carried, which then would have to be cream -but in the case of Torties it would make no difference whatsoever as you can only get Torties from Reds, Creams or other Torties (i.e. BlueCream, LilacCream, Tortie Tabby, Silver Tortie, Choc Tortie etc etc.). Also Reds and Creams are NOT always Tabby genetically, it is perfectly possible for them to be Self -but usually they have such heavy ghost markings that they LOOK Tabby. In many breeds a self red is referred to as a non agouti Red Tabby -silly really because they ought to only be reg'd as Red SELF. With a bit of practice you can learn to tell the difference -Red selfs have a coloured chin for instance, whereas a Red Tabby always has a pale chin. :)

Sorry to butt in again, forgot this part. Again it is IMPOSSIBLE to CARRY Red. Also there is no way a black x brown tabby could ever give Torties, one parent has to be Red gene (red, cream, tortie in any form).  It would also be very easy to work out what was what without knowing the background, as the only thing you wouldn't know would be if the parents carried dilute or not -and with the result it is unlikely that both did, seeing as all the resulting kittens were dominants.

What colour was the mother? In any event, the Torties are very easily explained as Red ("ginger") male x any other colour female= all female kittens will be Tortie. The litter you described could actually quite easily occur from just one male mating the queen. If she was a Tabby (or self Black) mated to a Red, all female kittens would be Tortie (in one form or another), but she could have Red males, Tabby males, and Black males if both parents carried the gene for self or if one was self . :) I'm not saying she wasn't pregnant with more than one sire, just that this particlar outcome could have hapened with just the Red/white mating her. :)

You're absolutely right Goldmali ;)  Red is dominant and CANNOT be carried by a Black, I'm getting my O's and o's mixed up :rolleyes: however you can get tortoiseshell from either a black/non red female and red male, or a red female and black/non red male ;)  The Orange gene being carried on the X chromosome,  a male cat needs only 1 red gene in order to have a red coat, whereas a female needs 2 red genes in order to have a red coat.  If she has only one red gene then the other gene is non red and she will be a tortie. 

The information I have states that all cats whatever their colour are genetically tabby but the non-agouti gene 'aa' responsible for self-coloured cats, is ineffective in red cats (and their dilutes) and therefore all red cats are Tabbies, but breeding has allowed Red cats to be bred with a dissipated pattern so as not to be noticeable. I have a friend who used to breed Self-Red and Cream Persians and the kittens often had faint barring, especially on the heads and legs :)

I used to breed Blue and Lilac Burmese and was fascinated by the appearance of tabby 'watermarks' on their heads, they had no red genes at all and weren't tabby (or rather the gene was 'switched off'), but at a certain age the watermarks would appear, then when the adult coat came through properly it would disappear, apparently Black kittens can show this 'watermarking' too :D :D

Mum was black and believe me, ANY of those could have been dad!!  My guess it was ALL of them!

Complicated, isn't it? 

That makes sense jackyjat, and yes, it quite possibly was all of them even though like I said the red/white COULD have produced all those colours :)

>however you can get tortoiseshell from either a black/non red female and red male, or a red female and >black/non red male

yes that's what I said -one of the parents have to be red series. :)

Yes that is correct in so far that you will always get the markings (although selective breeding will minimise them) -but you can still have a SELF red which when mated to another self, say blue or black, CANNOT produce tabbies. :) Yes you may get more reds that LOOK like tabbies, but you cannot possibly from such a mating get any other colour tabby such as a black (brown) or blue for instance. In fact I used to have a Red Tabby stud who IS a true Tabby, and I took great delight in mating him to a self bue and a self black, producing blue and brown tabbies, proving that he was in fact tabby -when others in the same breed never managed anything else than more red tabbies as their red boys were in fact self. :)

And there was me thinking that this was a DOG site??? LOL :D :D :D :D MIOW
