What to expect when your dog’s expecting: A dog pregnancy guide

Whether or not you’re planning on breeding your pup, there’s a lot of value in learning about dog pregnancy stages and how to care for a dog who’s expecting. As adorable and exciting as puppies are, do you know how to handle what comes first?

If you look at dog pregnancy week by week, it’s much simpler to understand. You’ll be able to break down the tasks and to-do’s, so you’ll always be able to give your expectant pup the love and care she deserves. Here’s what you need to know:

How long is a dog pregnant?

Although there is an answer, the reality of every pregnancy will vary. The American Kennel Club reports that the average gestation period for a dog is 63 days from conception to birth. This varies because it can be nearly impossible to tell exactly when conception occurs in canines. Once mating occurs, sperm can stay alive inside the female for up to a few days.

Dog pregnancy stages

Since gestation for pups lasts only nine weeks, it’ll move a lot faster than a human pregnancy. For more information, Baldivis Vet Hospital provides week-by-week dog pregnancy guides to keep you in the know.

Month one

During the first week after mating, the embryos will move toward the uterine horns — though they don’t attach to the wall just yet (via BVH). This happens during week three. Until then, they stay safe in the uterus, so your sweet dog can maintain her normal routine — unless your vet says otherwise, of course!

During week four, your pup will start showing pregnancy symptoms: fatigue, morning sickness, and increased appetite. You may also notice enlarged nipples and a clear vaginal discharge, though your vet will also use blood tests and hormone levels to confirm your dog’s pregnancy and provide a clean bill of health (via BVH).

By the end of the first month, each fetus will begin to take shape. The AKC estimates that fetal heartbeats can be detected by day 30 of gestation.

Month two

Around week five, the embryos are now considered fetuses. Organs begin to form, and each fetus will grow significantly in the coming weeks, which is when you can expect to see (and make) many changes (via BVH).

By six and seven weeks, the real development begins. The claws and coat form and the skeleton hardens around day 45, and your vet may be able to tell how many puppies are in the litter (via AKC). It’s also a good idea to have your pregnant dog preemptively treated for worms to keep the puppies safe, though she may be more interested in nesting.

During week eight, begin preparing your dog’s nesting — or whelping — area. Some noticeable changes to look out for in your dog during this second month include:

  • Increased appetite until day 45, then decreased appetite
  • Growing abdomen, visible movement from puppies
  • Weight gain
  • Frequent urination
  • Behavioral changes

Month three, including birth

About one week before whelping, your dog will start producing milk (via BVH). Don’t use this to guess when labor will be, though it can be a heads-up. You’ll want to keep puppy formula on hand, too, just in case.

Around this time, the puppies will be noticeably lower in the abdomen as they move into the birth canal. Your dog will continue to be restless and will experience a small drop in body temperature about 12–24 hours before labor begins.

In the first stage of labor, look out for increased nesting, clear vaginal discharge, and other signs of stress in your pregnant dog. She will naturally move to her ideal nesting area, so you might have to rearrange a few things to keep her comfortable.

Generally, a dog will handle labor and birth like a champ completely on her own, as the process isn’t as dramatic as a human birth. Still, you should be nearby to make sure everything goes smoothly. You may have to gently open the fetal sac of each pup if the puppies are arriving right after one another.

Each delivery should last one to two hours, though it varies. This is when it’s helpful to know how many puppies to expect, so you can know when delivery is done or if there are any complications. Don’t forget to have your vet’s number on hand just in case!

How to make your dog’s pregnancy easier

The best thing you can do for your dog in the later stages of pregnancy is help her create the most comfortable nesting space possible. It should be someplace quiet and warm, with plenty of blankets, sheets, or even newspaper that can be changed or cleaned frequently.

Your vet will be able to provide the most accurate details on caring for your dog and her pups after birth. They’ll also be able to guide you throughout each stage to keep your dog in the best health possible — diet and hygiene are so important when it comes to canine pregnancy!

With the proper care and TLC, your dog’s pregnancy will be a breeze. Before you know it, your home will be filled with little barks, tiny paws, and so many smiles.

Why is my dog drooling? Here’s when to be concerned about sudden or excessive dog salivation
This is why your dog slobbers all over you and themselves
A drooling Irish Setter looks to the side

Although St. Bernards, Mastiffs, and several other large breeds are known for their tendency to drool, it may be quite a shock if your usually drool-free pup suddenly starts to salivate. Luckily, you’ve come to the right place if you find yourself asking, "Why is my dog drooling?"
We’ve looked into many causes of excessive and sudden salivation, from the easy fixes to the more concerning problems. Most likely, drooling is nothing to worry about, but it never hurts to take a more careful look — especially if your pup is behaving oddly. Here’s everything you’ll want to know about canine salivation.

Why is my dog drooling and is sudden or excessive drooling a cause for concern?
Though drooling has many harmless causes, which we'll cover later in this article, you may want to keep a closer eye on your pet if you notice sudden salivation — especially if it’s a large amount.
Nausea and stomachaches are common causes of sudden drooling for dogs, although they will be temporary. If you think about it, many humans experience the very same thing! You may also notice vomiting or lethargy if your pet has ingested something they’re not supposed to, so don’t hesitate to contact your veterinarian if you’re concerned about your best buddy’s wellbeing.
On a more urgent note, dogs may also salivate if a foreign object becomes lodged anywhere in the mouth or throat. This can become a dangerous situation if the object blocks their airways, so you should waste no time in getting your fur baby to your closest veterinarian’s office if this could be the case.
Excessive, sudden drooling can also occur when a dog is overheated. Ashely Gallagher, DVM, explains that although salivation can act as a way of cooling off, just like panting, dogs don’t usually resort to this technique unless they are having trouble regulating their temperature through panting alone.
One last cause of sudden drooling is an upper respiratory infection. An illness of the nose, throat, or sinuses is more likely for pups who have been in group settings, such as shelters or kennels, but any dog can catch one, according to Amy Flowers, DVM. Luckily, your veterinarian will be able to guide you toward the best treatment for your furry friend. In most cases, it's a quick fix!
