If you have a dog that is pregnant, you may have started to think about how many puppies will be born in the next few months.
You have to start preparing for all those cute puppies and buying supplies, so it’s important to know what to expect.
We’ll help you out by telling you what the average size of a dog litter is, going over some of the reasons why litter sizes can vary, and giving you some other interesting facts about dog pregnancy. Let’s get started with this party!
How Many Puppies Can a Dog Have?
Near the end of your dog’s pregnancy, your vet should be able to feel her tummy or take an x-ray to figure out the “exact” number of puppies in her belly. However, it’s easy to miss one of the puppies, so you won’t know for sure until the little wigglers start coming out.
Even if your pregnant dog mom isn’t far enough along for your vet to tell you how many puppies she’s carrying, it’s helpful to have a general idea.
In 2011, a book came out with a pretty thorough look at the subject. The researchers looked at more than 10,000 litters from 224 different dog breeds. They found that the average number of puppies in a litter was 5.4.
There are, however, some differences.
Most litters of small breeds had 3.5 puppies, but litters of large breeds had 7.1 puppies.
How many puppies will a Blue Heeler have in a litter?
A litter of Blue Heelers usually has five puppies. But the dog usually has anywhere from one to seven puppies at once.
Blue Heelers mate every two years, and the process takes about three weeks. During this time, there is a good chance that the blue heeler will get pregnant.
In this guide, I’ll talk about how many puppies a Blue Heeler can have, how long it takes for a Blue Heeler to get pregnant, what factors affect the size of the litter, and how you can make sure your dog has a healthy pregnancy.
As the owner of a beautiful Blue Heeler mom, I’ve tried to learn as much as I can about their needs, way of life, and habits. So, I know how many puppies a Blue Heeler can have.
I also used facts from reliable sources like the AKC to give you the most accurate information I could.
Factors that Influence the Size of a Blue Heeler Puppy
According to a Norwegian study, the number of puppies a dog, like the Blue Heeler, has depends on the following factors:
The Size of the Breed
Surprisingly, their small size is also based on how big the dog is. Large dog breeds often have a lot of puppies at once.
For example, a German Shepherd can have anywhere from one to fifteen puppies in a litter, with eight being the average.
As a medium-sized dog, the Blue Heeler can have anywhere from one to seven pups.
The Mating Method
The American Kennel Club says that natural mating leads to more puppies than artificial breeding.
When fresh or cool sperm is used for artificial insemination, the number of babies born can drop by 15%. When frozen sperm is used, the number of babies born can drop by 25%.
Age of the Female
Age is also a big factor when it comes to breeding dogs. A Blue Heeler that is two years old can have one litter of five to seven pups.
A female dog between the ages of three and five can have between four and eight pups.
A litter of 6–7-year-old puppies might have anywhere from three to eight pups. At age 8, a Blue Heeler can have anywhere from 2 to 8 puppies.
At age 9, a Blue Heeler can have anywhere from 1 to 8 puppies. As you can see, the average size of a dog’s litter gets smaller as the dog gets older.
Age of the Male
The age of the father also affects how many pups are born. When the dog turns five, the quality of his sperm starts to get worse.
The dog’s physical health can also affect her ability to have puppies and, by extension, the number of puppies she has. If you want to have puppies from a Blue Heeler, she needs to be in good shape.
She should have all of her shots and not have any underlying or long-term illnesses. She should have a healthy weight and not be hungry. If you need to vaccinate the blue heeler, do it at least three weeks before her cycle.
Time of the Year
When a baby is born in the spring, it is bigger than when it is born in the summer. But sometimes the difference is not that big.
Most likely, what a hen eats affects how many eggs she lays.
If you feed your dog a healthy, well-balanced diet, it will have more puppies than if you feed it homemade or low-quality food.
Gene Pool Diversity
Individual Genetic Factors
Dogs are all unique and different in many ways, including the size of their litters. This is hard to predict, but if all other factors stay the same, dogs with big litters are more likely to have big second and third litters.
It’s important to note that most of these traits come from the female dam rather than the male sire.
On the other hand, the size of the litter is partly up to the sire. The size of the litter he fathers will depend in part on how healthy he is, how old he is, and what genes he has.
What’s the Largest Litter Ever Recorded?
In 2004, Tia, a Neapolitan mastiff, gave birth to 24 puppies through a Caesarean section. This was the largest litter ever recorded.
This is a clear outlier, since most dog litters are much smaller than this one. In fact, most litters of Neapolitan mastiffs have between 6 and 10 puppies.
Some other well-known cases of animals having lots of babies are:
- A Springer Spaniel gave birth to 14 puppies in 2009.
- An Irish setter gave birth to 15 puppies in 2017 (on Mother’s Day, no less).
- A white German shepherd named Mosha gave birth to 17 puppies in 2015.
- In 2016, a Maremma sheepdog gave birth to a litter of 17 – which set the California state record for litter size.
- A bullmastiff produced a litter of 23 puppies in 2014.
- In 2014, a 3-year-old Great Dane gave birth to a litter of 19 puppies.
How Many Litters or Puppies Can a Dog Produce in Her Lifetime?
As we’ve already said, the number of puppies in a litter depends on many things, but for the sake of argument, let’s say she has about five puppies in each litter.
That means, again, that a single dog might be able to physically have up to 70 puppies in her lifetime.
This, on the other hand, would be crazy.
If a dog was bred this many times, it would probably hurt her health, and this kind of fast breeding is more common in puppy mills and with people who don’t care about the health of their dogs than with people who do.
Also, there are some companies that won’t let you register an unlimited number of litters. For example, you can only register up to six litters from a single mother dog with the Kennel Club of the United Kingdom.
What is the Duration of the Gestation for Blue Heelers?
It can be hard to know exactly when your Blue Heeler gives birth because the dog might not get pregnant on the same day that it mates. The sperm can live in the dog for a few days after mating.
The egg can also stay alive for up to 48 hours. So, the day the animals mate doesn’t give a good idea of when the puppies will be born.
But the average time for a dog to be pregnant is 63 days, and it’s common for the dog to give birth a few days earlier or later than this.
Dogs give birth much faster than people do, and every day is important for the dog’s health.
Knowing how long a Blue Heeler’s pregnancy lasts could help breeders take care of the dog’s diet and health.
Ensuring a Healthy Pregnancy in Blue Heelers
Here are some things to think about to make sure your Blue Heeler’s pregnancy goes well:
- Make sure that your Heeler gets a healthy, well-balanced diet. If you want to breed the dog, you must make sure it gets all the nutrients it needs to get pregnant and stay pregnant.
- Your Blue Heeler shouldn’t be too heavy or too light, so make sure it eats enough and doesn’t get too many bad snacks.
- Make sure your Blue Heeler goes to the vet often so that any health problems can be ruled out.
- Make sure your horse gets enough exercise so it stays healthy and fit.
How Long Does a Dog Carry Her Puppies?
The average length of a dog’s pregnancy is between 58 and 68 days. This could be different depending on a number of things, like the age, health, and breed of the female.
It can also be hard to know exactly when a person gets pregnant, which gives this statistic some room to move.
But for most things, you can assume that your dog will be pregnant for at least two months.
What Are the First Signs of Pregnancy in a Dog?
There aren’t many early signs that your dog is pregnant, which is a shame. Most of the time, you’ll need to wait three to four weeks before you can tell if you’re pregnant or not.
Here are some of the most common signs that a woman is pregnant:
- About a month after mating, your dog may have a mucus-filled discharge from her uterus.
- About a month after mating, a pregnant dog’s teats will get bigger and slightly change colour.
- Some dogs will start dripping a semi-clear fluid from their nipples about a month after mating.
- Around the third or fourth week of pregnancy, many dogs get “morning sickness.” This can include things like vomiting, changes in appetite, feeling tired, or acting strangely.
- Around week four, your dog will probably start to gain weight. Most dogs weigh about 50% more after giving birth than they did before.
- Around the 40th day of pregnancy, your dog’s belly will likely start to get bigger. This isn’t always easy to see, especially when a dog has a small litter.
- During the second half of her pregnancy, your dog will probably start to eat more.
If you think (or hope) that your dog is pregnant, taking her to the vet is the best way to find out for sure. Most breeders say that two to three weeks after mating, you should take your pet to the vet.
Between the 28th and 35th days of pregnancy, your vet can also safely feel your dog’s abdomen. This way, he or she can be sure that there are puppies in her uterus.
It’s important to note that this is a very delicate technique that shouldn’t be done by anyone who hasn’t been taught how to do it. Rough treatment of babies in the womb can hurt them or cause them to die.
By day 45, your vet will be able to use an X-ray to look at the mother and see how the babies are growing. This lets the vet not only count how many puppies are there but also look at their bones and see if there are any problems.
First Time Mothers: What to Expect
Most dogs are great mothers for their second, third, and so on litters, but first-time moms often have trouble figuring out what to do.
So, you should keep a close eye on first-time moms to make sure everything goes well and she does everything a good mom should do.
You must ensure that all of the puppies find nipples and consume enough food to keep their bellies full and bodies warm.
You’ll also want to make sure that the mother is healthy and happy during the whelping process. If she gets sick or sad during this time, the puppies are likely to suffer.
This makes it much easier to keep an eye on everyone and spot problems before they get out of hand.
Life History and Litter Size
Large litters might seem like a good trait for any species to have, but in reality, things are rarely that simple.
In reality, litter size (or clutch size in species that lay eggs) is a very important part of how animals have changed over time.
Most of the time, the best litter size for a species’ life history and survival strategy is determined by the pressures of evolution.
For instance, some species, like humans, elephants, and hippos, often have very small litters with only one or two babies. These animals live for a long time, have high survival rates, and often put a lot of time and money into raising each child.
On the other hand, some mammals have a lot of tiny babies all at once.
The tailless tenrec, a strange mammal from Madagascar that eats insects, usually has about 15 babies, but there have been cases of more than 30 babies being born at once.
These animals have a high death rate, don’t live very long, and only put a small amount of resources into each of their offspring.
All dog breeds have an average litter size of about five puppies, so dogs are in the middle. They spend about the same amount of money on each child and live for about the same amount of time.
The One-Half Rule
The number of nipples a species has is also affected by the many things that affect the size of a species’ litter.
The biggest litter size is usually the same as the number of nipples, while the average litter size is usually about half the number of nipples.
People are a great example: most moms only have one child, but it’s not uncommon for them to have twins. This makes sure there are enough nipples for everyone, and it also protects the baby if some of the mother’s nipples don’t work right.
Dogs also do well with the one-half rule.
Most dogs have eight to ten teeth, and the average size of a litter is five.
I once had a small chocolate lab who had two litters of nine and ten puppies. They were a lot of work. I can’t even imagine having to take care of 15 or 20 puppies in a whelping box.
Formulas that replace puppy milk and feeding tools are important in these situations to keep the whole litter alive (and not drive poor mom out of her mind).
