If you take her in immediately, she can be treated with diethystilbesterol (DES) tablets for 5 days. This is the closest thing to a “morning-after pill” for dogs, but it may not even work. DES can cause serious side effects, each of which can lead to other complications.
Alizin® is a safe and effective drug treatment for mismating that induces abortion in dogs.
Contraceptive pills for female cats and dogs that contain megestrol acetate or medroxyprogesterone acetate (see table below) are effective, provided that users comply with the conditions for their use, particularly the timing during the sexual cycle and the frequency of administration.
Safe and effective termination of pregnancy is possible in both dogs and cats by administration of prostaglandin F 2alpha (natural hormone) at 0.1 mg/kg, SC, three times a day for 48 hours followed by 0.2 mg/kg, SC, three times a day to effect (until all fetuses are evacuated as confirmed by ultrasonography).
Week 1-2 of Dog Pregnancy
eggs in the female are fertilized by sperm from the male. This can happen within a week after mating, although it does not always happen with every mating attempt.
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.
Immediately after your female dog has been mated, is there anything you should do? Make sure that she does not have the opportunity to mate with any other dogs. Remember that oestrus will continue for several more days and she could theoretically become pregnant from another dog during this period.
Does Getting Stuck Mean the Female Dog Is Pregnant? The longer dogs are stuck together in a copulatory tie, the greater the chance that the semen will reach the eggs. But pregnancy in dogs is never guaranteed, Greer says, "Just like in people, not every mating is successful."
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.
Since sperm can remain in the female dog's reproductive tract for up to seven days, female dogs don't have to ovulate on the day they mated to become pregnant. If a female dog has mated with two or more male dogs, she can have puppies from different dads in the same litter.
After a female dog has mated, you can expect changes in behavior like becoming clingy or irritable with other dogs. She may be lethargic and show signs of morning sickness. Physically, she may gain weight and have larger, discolored nipples.
Figure 5-4 A to D, Once the tie occurs, the male dismounts, swings his leg over the female's back, and stands facing in the opposite direction. Ejaculation occurs throughout most of the time the tie is maintained. The sperm-rich portion of ejaculate is usually produced during the first 2 minutes.
In the first few weeks, there are very few outward signs, so you may not notice a change. Your dog will seem like their normal self, although they may gain some weight. Morning sickness affects some dogs, but only for a few days during the 3rd or 4th week. (It's caused by hormone changes.)
The jury is out on an absolute answer but there are some clues concerning observed traits. The first born tends to be a more focused or a one person type of pet. First-borns are usually the choices of professional dog trainers. Runts, on the other hand, may need more nurturing, but they are fun, frisky pets.
In other words, if there is a large age gap between the sire and dam, you get litters full of males, while if the sire and dam are approximately equal in age you get litters containing more females.
A best practice is 4-6 litters per dog
Reasons that a reputable breeder may have to retire a dog sooner would be difficult deliveries that may require C-sections or other common reproductive related difficulties such as recurrent mastitis or uterine infections.
A normal litter size can range from 1 to 12 puppies, with 5-6 puppies being average across all dogs. But just as every breed of dog differs by size, function, and personality, they also differ when it comes to litter size, according to AKC registration data.
The right time to breed your dog is when she is around two to three years old. Her body has then become fully matured to take on the full stress of pregnancy and the things that come after.
a) Dogs and cats are not like people when it comes to sex. They don't cycle the same way and there's no evidence, behaviorally or otherwise, that sexual activity brings them any specific pleasure akin to orgasm, for example.
Despite this silly law, dogs will tend to mate wherever they have the opportunity, just like wild dogs do. If we take a look at the way dogs and their wilder cousins are wired to love and mate, we may understand a little bit more about what makes mating in public no big deal for them.
