The easiest way to tell if a male dog is neutered is to look at his penis. If the penis is completely smooth, the dog is neutered. If there are any bumps or ridges on the penis, the dog is not neutered.
Puppies are literally the cutest thing on the planet. The toebeans! The puppy breath! The high-pitched yips! There's so much to love — but pet parents who welcome a litter of precious pups into the world will have their hands full caring for Mom and her fur-babies.
What age can dogs have puppies? It depends on their size and breed, but your dog can become pregnant during the first heat, or estrus cycle.Though most dogs experience estrus around 6 months of age, some small breeds can go into heat at four months old, so it won't be long before your little princess is able to have pups of her own! (Breeding during the first heat isn't recommended, though, because the pup is also still growing.) Larger breeds may not go into heat for the first time until they're 12 to 18 months old.However, each dog is unique, and it may take several years for the cycle to stabilize.
Female dogs can continue to become pregnant and give birth throughout their lives, though the time between cycles may increase with age, and health issues may make pregnancy more dangerous.nbsp;Continue reading to learn about the history and science of pregnancy in dogs, as well as some tips and tricks for breeding responsibly.
Signs That Your Dog May Be Pregnant
When Princess goes into heat for the first time, also known as estrus, this stage of the reproductive cycle occurs roughly every 6 months and lasts from 2 to 4 weeks.Female dogs can only become pregnant during this period.
Behavioral changes and other symptoms may occur during all four stages of estrus, just as they do in human females. Behavioral changes typically occur during proestrus, which occurs just before the dog is most fertile.You'll know your dog is in estrus when she starts "flagging," or moving her tail to the side to signal to males that she's ready to mate. Vaginal bleeding and watery discharge are also signs of estrus.
If your dog is fertile, she will exhibit the following symptoms:
Here are some more indicators that your female dog is in heat:
The History of Dog Pregnancy
Did you know that dogs and gray wolves shared a common ancestor between 20,000 and 40,000 years ago?nbsp;To begin discussing the history of dog breeding, we'll need to go back about 14,000 years, to when humans first began domesticating wolves.
While the exact process of domestication is still being debated in the scientific community, it is thought that wild wolves inadvertently initiated the process.nbsp;(In fact, some people believe we didn't domesticate dogs, but dogs domesticated us!) Packs of wolves hung around hunter-gatherer tribes in the hopes of finding food. Tame, well-behaved wolves were better at scavenging scraps thanThose wolves evolved to be friendly to humans over time, and in exchange for food, the packs protected and assisted humans in hunting.
These dogs, however, were not the cuddly and well-groomed puppers who like to play fetch and nap on our couches; they were free to roam, and their physical characteristics were more or less uniform.So, how did those devoted stray dogs evolve into the 400-plus dog breeds we know and love today? It all comes down to selective breeding.
Humans discovered that we could breed dogs to improve certain traits that benefited us around 9,000 years ago in southern Asia. At first, we began breeding dogs for agility and hunting prowess.These were the first herding and hunting dogs. (Fun fact: ancient Arctic humans successfully bred their dogs to help them hunt down polar bears!)
As wealthy British aristocrats began experimenting with selective breeding, kennel clubs were established to keep track of the new breeds that competed in fashionable dog shows.nbsp;
To cut a long story short, we can thank Britain's upper-class Victorians for beautiful dog breeds like the Golden Retriever and English Setter, and the rest, as they say, is history!

Dogs are most likely to become pregnant during the second stage of estrus, which is described briefly below:
How to Determine Whether Your Dog Is Pregnant

How Long Can Dogs Remain Pregnant?
Pregnancy can last between 8 and 10 weeks after conception, but it usually lasts 9 weeks.
What Are the Dog Pregnancy Stages?
What Are the Labor Stages in Dogs?
Labor typically lasts 3 to 12 hours, with contractions beginning 12 to 24 hours before labor, and dogs delivering healthy puppies every 30 minutes to an hour.The delivery of each individual pup should not take more than 2 hours, and the placenta will follow after your dog has delivered the pups.If your dog's labor lasts more than 24 hours, contact your veterinarian right away.
Training Dogs to Get Pregnant
There's no need to train your dog to get pregnant — puppy love is a natural instinct! However, there are some things you should do if you want to breed your dog. Keep in mind that caring for a pregnant dog and newborn puppies is a daunting task and a significant commitment.The effort, however, will be well worth it when you welcome that adorable pack of puppers into the world!
The first step is to ensure that the female dog is ready to breed; a female dog can breed during her first heat.Most dog breeders, however, wait until a female dog has gone through three or four menstruation cycles, at which point the female dog is fully physically prepared to endure the taxing experience of pregnancy.nbsp;
Here are some guidelines for breeding your dog responsibly:
Take both the male and female dogs to the vet before pairing them up to ensure that they are both in good health. Allow your female dog to spend time with the male during the second stage of estrus, when she is most fertile, which lasts about 5 to 10 days.
Don't worry, this process doesn't have to be too formal; you can still hang out, play, cuddle, and walk your dogs as usual.A happy dog is a healthy dog, and healthy dogs breed more healthy dogs, so keep both the female and male dogs on a very healthy and wholesome diet while breeding.nbsp;
