Can a dog get pregnant by two different male dogs ?

Question

Can a female dog in heat get pregnant by two different male dogs and have two different breeds of puppys?

Answer 1

yes and so can cats, even humans in some very strange cases! i went to highschool with twins that had different fathers!!! i know it sounds crazy but it is true! they looked nothing alike but were born 4 hours apart. they did a science report on themselves and their mom even came to the school to talk about it.

Answer 2

Yes she can. I had a female that I bred with a male (same breed) Then I had an emergency & had a friend take care of the dogs. Without thinking, she let all the same-breed dogs play together. I found later that my female had mated with a different male. When the pups were born, 7 had Mom & Dad's coloring but 1 was a solid opposite color. He was a cutie! So I registered the litter of 7 and gave the oddball to a little girl down the street who's parents couldn't afford a dog. I still take them to the vet with my own and pay for the shots & worming. I always seem to buy 1 extra bag of food each month & she is happy to bring her dog in her wagon to take it off my hands.

This has even happened with humans. Very very rare though. Each egg needs one sperm. Once it has a sperm it accepts no more. However, since dogs generally will ovulate many eggs, they must all get their own individual sperm. And if the female has sex with more than one male withouth much wait between. Then the sperm will race each other to be the first. It also has something to do with the time of the ovulation of the females eggs as well. And from what I understand, boy sperm and girl sperm swim at different speeds and have different life spans. So that might also have an effect on the outcome. But it is possible.

Answer 4

Yes she can! On both counts! During her cycle she can breed with how ever many males she is exposed to. The problem is that the pups will not all develop due the amount of gestation time for a dog. She has about 61-64 days to deliver her pups. The ones FIRST conceived will generally make it. Dead pups are more than likely additional breeding's beyond her gestation period. Thus stillborn pups, "runts" may be due to 2nd and third breeding's after the first week of HEAT.

Allow her to breed at least twice with the same male. To insure that she is pregnant. Then keep her away from additional breeding's for HER health and safe delivery of the pups you want.

Point in fact........

I have a male Jack Russell and wanted to breed him with a friend of mine's female Jack? The friend brought her over when she noticed her in heat? I mated my dog with her twice, I watched them tie-up.

My agreement was to give all care to the female and pay all costs, food, vet bills and whatnot? When the 6 pups were born they were all part Labrador, way too large for the Jack female to deliver? I paid a huge vet bill. 5 of the pups were Labrador mix, the 6th pup was stillborn/undeveloped, a tiny black/white Jack just like my male. Due do the fact that the female had been bread before she was brought to me. She mated with my dog beyond her gestation period.

Be careful NOT to allow several breeding's..........

Answer 5

Yes, dogs and cats and probably other animals don't actually ovulate until after the first act of intercourse during heat. That's why you see so many different colors of kittens from same mom. Not so often with dogs, maybe because the male is usually there with the female for a while. Perhaps they talk after, then decide to go again, who knows?

Answer 6

While strange, if a dog (or a cat) mates with two or more males in the same 24hour period, the litter has a chance of being fathered by the different dogs. It doesn't mean that if your labarador mates with a Shar Pei and a poodle that the dogs will be lab/Shar Pei/poodles, it means that some will be lab/Shar Pei and some will be lab/poodle. This is because dogs release more than one egg for each heat cycle. One egg doesn't split to form the litter, except in the case of identical twins.

It's also possible (to a much lesser extent) for the same thing to happen to humans, with more than one egg being released and more than one mate. So fraternal twins, in theory, could have different fathers.

Answer 7

Yes, it is possible. I heard of a woman once who got pregnant and then found out a month later that she was pregnant again. The babies were conceived at different times. They had to be delivered together and were thus twins, even though they really weren't. Got that?

As for puppies, I'm not sure the dog could have that many inside her, but yes, it could happen.

Answer 8

A dog can not get pregnet by 2 male dogs at the same time. She could mate with more than 1 male, but only 1 male dog can fertilize her eggs in one pregnancy.

Answer 9

yes a female dog can have a litter with several differnet males being the sires of the puppies. whatever her breed is will be mixed with the male dogs breeds. my neighbor had a dog..a litter of 8......4 different breeds....so yes it can happen and does all the time.

Answer 10

Yes she can. Say if 3 males bred her, each a different breed, she could have pups by each male.

The poster that said this "Yes, but it wouldn't be like one pup is a Lab X Husky and another is a Lab X Golden, all the pups would be Lab X Husky X Golden. " is wrong. The pups would not all have genes from each of the males. Each pup would be out of one of the males, not a mixture.

Answer 11

I only know this by experience. My dad loved his pointer hunting dog. She was white with a little long hair and liver spoted.She had puppies from 3 of the neighbor's dogs! From down the hill came a black and white rat terrier, from up the hill came a light brown chow and a chocolate wennie dog! She had the craziest bunch of puppies you have ever seen and I was happy! I could interact with regular dogs but not Dad's hunting dogs! There were short legged pointers,chow with long bodies,a couple of short haired but the color of the chow,and one smallish terrier but his head was more like the wennie dog!!! One day when I got home from school the puppies were gone! Dad said they must have been lost in the tall Johnson grass,that we baled for hay, and couldn't find their way back. I wasn't young enough to fall for that one anymore and I was mad. The same mama dog was pregnant the next year by a "good hunting dog" and she got cranky and broke my terriers back and killed her! I took the garden hoe and was going after that dumb dog but my mom and brother caught me because they didn't want me to get in trouble with dad. To top it off, when she delivered the puppies she got out of her fenced area and went under the house. Guess who had to crawl under and get the puppies? I was scared because even the friendliest of dogs can get upset when you start putting their new puppies in a box in a dark and very low crawl space.And of course I had to go the full length, of the pier and beam house, to get to them and then drag the box out while watching for mama dog and spiders and snakes!
