The answer: Yes! The scientific term is called superfecundation, and it happens often among un-spayed, stray females who mate with two or more males.
If two male dogs mate with the female on the same day, it's a straight swimming race between the sperm as to which reaches the ovum first and fertilizes it. If different males mate with the female on different days, she can fall pregnant by both of them.
The fertility rate in a slip mating is not quite as good, as there is often some spillage of semen when withdrawal occurs prior to the locking phase. However, conception is still possible and even likely, providing ejaculation occurred prior to the dogs' separating.
How many times should a dog mate to get pregnant? Although a dog can get pregnant from one mating, most stud dog owners will recommend the dogs mate two (or even three times), usually 24 – 48 hours apart each time, but this may depend on whether a tie or a slip mating has been achieved.
Male dogs are sexually active year-round and can be capable of siring puppies when they're as young as 5 months, but they are most fertile after 12-to-15 months of age, once they are fully physically mature.
As with anything else, different veterinarians will have a different opinion on the best age to start breeding your male dog. However, most veterinarians recommend waiting until at least six months, with many pushing that back to a year.
The sperm will last inside her for about five to seven days, so if you breed her as soon as she is willing, then breed her again every two or three days until she is no longer willing to allow the male to mount; this means all of her eggs will be fertilized.
Most dogs, given the opportunity, will end up mating when the female is in heat. A whopping 40% of female dogs will fall pregnant after just one mating session! That incredibly high number means you are at considerable risk of having a litter of unwanted puppies if you are not careful.
Dogs new to mating may experience a bit of anxiety at being locked together, but it's a natural process. Help your dog to remain calm and stand still until the two can safely separate. This will occur on its own once the male dog's arousal subsides.
You might be tempted to try to separate dogs when they're stuck in a copulatory tie during mating. But hold up: Pulling dogs apart can seriously injure them and doing so won't stop a pregnancy from occurring. Instead, encourage your dog to remain calm.
For most females, the best time for breeding is between the tenth and fourteenth day of estrus. However, some females ovulate as early as the third or fourth day or as late as the eighteenth day. It is normal to arrange for two matings (also called stud services) for your dog, often 24 to 48 hours apart.
The male will mount her, and after breeding will remain attached to the female for 5-20 minutes; this is called the tie. It is natural at this point for the dogs to be joined facing in opposite directions. Leave the dogs alone until the tie ends naturally.
Dogs scream when mating for many reasons, including stress, anxiety, pain, and being bred too early. Always supervise your dogs as they mate to prevent injuries and stress.
It also appears that being in a "tie" ups the chances for pregnancy in dogs. A tie occurs when the male and female dog are stuck for some time. However, some dogs have also become pregnant without a tie, and some dogs don't get pregnant despite tying, so it's not a guarantee.
It's Not Really About Sex
Since mounting can be unrelated to reproduction, its social significance applies to both males and females. Because it is a display which serves to challenge or to assert social control by one dog over another, this behavior can occur between individuals of the same or the opposite sex.
Male dogs have homosexual sex under a variety of circumstances. They mount each other in dominance displays, and that mounting can involve anal penetration.
Answer: When a dog is in heat, they tend to be willing to mate when their bleeding starts getting more diluted and pinkish. It is normal for a dog in estrus (heat) to continue to have bleeding even after they've been bred.
– A dog pregnancy can vary between 56 – 70 days. Typically, puppies should arrive about 63 days (just over 2 months) after conception.
Yes, a neutered dog can still lock (have sex with) with a female dog, as the neutering procedure only removes a dog's testicular sacks. While neutered dogs cannot impregnate a female dog and therefore make babies, they can most certainly still have sex.
A common question is, “Can a dog get pregnant when not in heat?” The answer is no, a dog cannot get pregnant when she is not in heat, however, many pet parents may not recognize the full heat cycle of their dog and will only look for the noticeable sign of dog period bleeding.
Proestrus: Proestrus is the start of the heat period where your dog's body is preparing to mate. Signs seen during this phase include a swollen vulva, blood-tinged discharge, excessive licking of the genital area, clingy behavior, and aggression toward male dogs. Your dog may also hold her tail close to her body.
If you have an intact male dog, consider neutering him. Although neutering doesn't always stop a dog from mounting or masturbating, it does reduce his sexual motivation—especially if the behavior is triggered by the presence of a female dog who's in heat.
Not only do animals enjoy the deed, they also likely have orgasms, he said. They are difficult to measure directly but by watching facial expressions, body movements and muscle relaxation, many scientists have concluded that animals reach a pleasurable climax, he said.
Depressingly agrammatical and typo-ridden as it was, the question succinctly revealed an all-too-pervasive sentiment: Pets are like people. They like sex too. And when they can't get it, they––like us––act out sometimes.
