Is there anything more universally beloved than a puppy? From the tiniest of toy poodles to the grandest Great Danes, nothing unites humanity like our shared love for Man’s Best Friend.
There are nearly as many breeds of dogs as there are ways to praise them, which begs the question, how big do mixed-breed pups get at their adult size? The short answer is that it depends on many factors (not least the breeds involved) but the backgrounds of both dogs and the tendencies of their respective breeds are key.
A popular rule of thumb is your puppy’s adult weight and height will be four times what it is at four months of age.
For a longer, more in-depth answer, let’s break down those factors and see how big or small you can expect your mixed-breed puppies to be at their adult size.
The Puppy’s Parents
The first and most important factor in determining your mixed puppy’s size, as mentioned, will be both parent breeds. If you don’t know what they are, things can get a bit more complicated but don’t worry as we’ll cover later, there are workarounds you can use to calculate their probable size otherwise.
Seeing how big those parents are will give you a good idea of how big your mixed puppy might grow to be based on their heights and that of their breeds.
Breaking Down the Breeds
Speaking of which, the most mathematically-accurate way of determining mixed-breed pups size is a dog weight estimator, and with dogs adult weight typically being broken down into five main categories:
Toy Dogs (up to 12 lbs):
These are the tiniest of the tiny, and tend to stop growing at the eight- to nine-month mark. To calculate their weight, take the approximate puppy weight from around the six-week mark, double it, and then double that figure. Examples of toy breeds include the Toy Poodle, Maltese, Pekinese, Pomeranian, and Shi-Tzu.
Small Sized Breeds (12 to 25 lbs):
As with toy breeds, you want to take these dogs six-week weight, double it, and then double it again to get their approximate weight. They tend to stop growing a tad later than toy dogs, at the 9 to the 12-month mark. Examples of small breeds include French Bulldogs, Pugs, and Jack Russell Terriers.
Medium Sized Breed (25 to 50 lbs):
These dogs should likewise stop growing around the 9 to 12 months of age, with the biggest growth spurts happening within the first 16 weeks. Weight calculation is a little more complicated with these breeds. You can take the approximate puppy weight from around 14 weeks, double it, and then add the sum to half of that 14-week weight. Examples of medium breeds include Basset Hounds, Border Collies, and Whippets.
Large Breed Size (50 to 100 lbs):
These dogs will take a little bit longer to reach their peak weight, with around 12 to 18 weeks being a good ballpark estimate. The biggest puppy growth rate occurs in the first 20 weeks. There are two possible methods for calculating larger dogs’ weight. The first method involves dividing their weight at 20 weeks by their present age in weeks (for example, 18 if they’re 18 weeks old) and then multiply all that by 52. The second, a probably simpler method is to double whatever their weight is at 6 months, and voila.
Giant Breed Dogs (Over 100 lbs):
These gentle giant breeds likewise need a lot of time to grow, eventually topping out at around 12 to 18 months, although some of them can grow for as long as two to three years. (Incidentally, this is why you need to make absolutely sure you know what you’re getting into before you buy one of these behemoth breeds.) The most rapid growth rate for these giant breeds occurs up to the 25-week point. To calculate their weight, they use the same complicated formula used for larger breeds.
What If You Don’t Know the Breeds?
If you don’t know the breeds involved in your mixed puppy, you could always make an educated guess, or have a dog DNA test done on your puppy. You can also try and use those formulas just based on your dog’s height and puppy weight without knowing their exact breed. The results may not be as exact as if you knew the breed, but at least you should be able to calculate some kind of estimate on their adult weight.
Another way of knowing your dogs breed is to take a look at their coats. This is often one of the most telltale signs of what breed the dog is. If you see spots or colors that are indicative of a certain breed, that’s a good hint that at least some of your dog’s parentage lays there.
Gender is another important indicator, with males tending to be bigger than females at their adult size. You’ll also want to pay attention to the age at which you have your dog spayed or neutered since doing so eliminates the chemicals that cause bone growth to stop. As a result, earlier neutering won’t make your dog smaller – on the contrary, it may actually cause it to grow taller than it would otherwise.
Check With Your Dogs Vet
When in doubt about anything regarding your puppy’s health, you should always consult your veterinarian, and that goes for mixed breed dog growth as well. Your vet should have plenty of experience with observing puppy growth from different breeds, and so they can provide you with invaluable information. They can inspect your puppy and give you their best guess as to both the parentage of your puppy if you aren’t sure and how big they think it may grow.
How about the food you feed your puppy and its effect on their growth?
Overfeeding your puppy food can spur on its growth, but not necessarily in a positive way. It is important for a puppy’s weight and bones to grow at a healthy ratio to one another – cute as a big fat ball of fur may seem, if their bones can’t take it, overfeeding can cause your dog severe long-term bone damage and pain. That said, underfeeding your puppy isn’t the answer, either.
Your puppy should be fed and grow steadily, with no ribs showing for puppies under six months. You should be able to feel ribs when you firmly press their sides. Your puppy’s waist should be clearly identifiable, and its tuck should slope upward gently, being at its highest right at its legs.
Practical Examples with Huskies
Let’s put this into practice with one of the most popular choices for mixed breeding, Husky dogs.
For example, a Husky-Lab Mix, a popular choice among dog owners looking for a Husky mix, will likely weigh between 40 and 60 lbs and stand around 20 to 25 inches tall.
Other Husky mix height and weight breed size estimates include:
- Alusky (Alaskan Malamute/Husky): Average weight 60 to 100 lbs, average height 26 to 28 in.
- Samusky (Samoyed/Husky): Average weight 40 to 60 lbs, average height 20 to 24 in.
- Bordsky (Border Collie/Husky): Average weight 30 to 45 lbs, average height 18 to 22 in.
- Boxsky (Boxer/Husky): Average weight 35 to 75 lbs, average height 30 to 35 in.
- Horgi (Corgi /Husky): Average weight 20 to 25 lbs, average height 13 to 15 in.
- Dachsky (Dachshund/Husky): Average weight 16 to 60 lbs, average height 8 to 20 lbs
- Pomski: (Pomeranian/Husky): Average weight 20 to 30 lbs, average height 10 to 15 lbs
- Great Husky: (Great Dane/Husky): Average weight 90 to 130 lbs, average height of 21 to 35 in.
