Having my own mixed breed puppy I’m currently also wondering how large he’ll get because he just keeps growing!
You can scroll down straight to the calculator if you wish but first I’ll tell you some things that can affect how large your pup is still going to get.
What Affects The Size?
A good indicator of how large your pup will get is usually the paws. If your puppy is somewhere around 8 weeks old and already has these huge paws that don’t fit his rather small body at all, that’s a good indicator that he’ll need some time to grow into them.
Already at 8 weeks old my Aussiedoodle puppy (Standard Poodle x Australian Shepherd) had bigger paws than my 12-year-old Yorkshire Terrier, which to me at the time was crazy.
I had no idea that the paws grow so quickly and that my puppy was going to grow into them eventually but at that point, everyone knew that he was going to be a quite large dog.
Females of any breed tend to be a bit smaller than their male counterparts so if you’re looking for a smaller dog choose a female.
Every breed has a typical size. You shouldn’t be confused if a Great Dane just keeps growing and growing and turns out to be a huge dog with just as large piles of crap.
On the other hand, a Yorkshire Terrier tends to be a rather small breed that will rarely exceed 7 pounds (3 kg).
Now, of course, mixed breeds like Doodles or any other kind of mutt is harder to predict but this is where the parents come in.
The parent can be a huge indicator of the size that your puppy will become one day. When both parents are roughly the same size, the puppy should be too but when the parents have quite a different size, the puppy might be dead in the middle or take after one of the parents.
Meaning, when the parents are substantially different or there are multiple breeds involved, the puppy’s size can pretty much be a mystery to the owners.
I saw both parents of my own puppy and they were quite a bit apart size-wise meaning that my puppy could take after the mother or father and I’ll probably only find out once he’s done growing.
Overview Of General Breed Weights
Here are some weights of these breeds grown up so you can get some idea where your dog might be if you know exactly the breed or have a few general breeds in mind that might be mixed in.
- Labrador Retriever: 55-80 pounds (25-36kg)
- German Shepherd: 65-90 pounds (30-40kg)
- Golden Retriever: 65-75 pounds (30-34kg)
- French Bulldog: <28 pounds (<13kg)
- Bulldog: 40-50 pounds (18-23kg)
- Standard Poodle: 40-70 pounds (18-32kg)
- Miniature Poodle: 10-15 pounds (5-7kg)
- Toy Poodle: <10 pounds (<5kg)
- Rottweiler: 80-135 pounds (36-61kg)
- Yorkshire Terrier: 7 pounds (<3kg)
- Boxers: 45-80 pounds (20-36kg)
- Siberian Husky: 35-60 pounds (16-27kg)
- Great Dane: 110-175 pounds (50-80kg)
- Dachshund: 11-32 pounds (5-15kg)
- Australian Shepherd: 40-65 pounds (18-30kg)
- Shih Tzu: 9-16 pounds (4-7kg)
- Chihuahua: <6 pounds (<3kg)
But seeing as you’re here, you most likely don’t have a purebred puppy, as these are predictable most of the time.
Mixed breed dogs, like Doodles that have become popular in recent years, are harder to predict, especially if you don’t know anything about the parents of your pup.
Rescued puppies and shelter dogs are the hardest to predict, as you have to go off the looks alone to figure out what breeds are mixed in.
For example, my puppy is currently 16 weeks old and expected to grow to medium size, as he is an Aussiedoodle.
Seeing as he’s also a mixed breed, it can be hard to predict exactly how much he’s going to weigh.
He’s about 26 pounds right now at 16 weeks (12kg) and should grow up to be 84.5 pounds (39kg).
Finding Out The Size Through A DNA Test
Did you know that you can find out how large your pup is going to be by using the Embark DNA test (check the current price on Amazon)?
All you need to do is a cheek swap of your dog and send it in, wait for a few weeks and look at the results online.
The test results will tell you the estimated size the dog is going to be based on his DNA, if your dog is genetically predisposed to any diseases and show you his family tree.

I Don’t Know The Age Of My Puppy
If you got the puppy from a shelter, rescue or maybe from the street even, it can be difficult to figure out the age of the dog.
Generally, you could try having a look at his teeth to see whether he is already lost teeth and his adult teeth are coming in or if he already has his adult teeth.
The puppy and adult teeth can be identified by their size. The baby teeth are very small and there are large gaps in between the teeth. The adult teeth are a lot bigger and there won’t be any gaps in between the teeth like in the picture below.
Within the next week (at 16 weeks old) after I took this picture he lost another 4 teeth and his adult teeth started coming in too.
- At 2-4 weeks the baby teeth start coming in. You’ll first see the front teeth, then the Premolars (set of teeth in the very back) and at last the canines (really sharp and pointy teeth in between the two.
- At 5-8 weeks all of the baby teeth should have come in.
- Between weeks 12-16 the adult teeth start slowly coming in.
- Now all adult teeth will emerge over the next few months. The teething should be completed by month 6-8. Larger breeds can finish teething a little faster than smaller breeds.
When Will My Puppy Stop Growing??
Small and medium-sized breeds will be finished growing by around 8-12 months. Some of them will obviously be at the lower end of the spectrum, like the Chihuahua, and other dogs like the Australian Shepherd at the higher end.
Larger breeds like the German Shepherd can take 10-16 months to reach their adult size and the biggest dogs of all, like the Great Dane, can take up to two years to reach their full size.
Your puppy’s size depends largely on the size of the parents as well as the breed or multiple breeds that are mixed. Female dogs also tend to be smaller than males.
When you have a mixed breed puppy it’s hard to predict where on the scale he’ll land but you can calculate a prediction of where he might be on the scale.
If you don’t know the age of your puppy, you can have a look at the teeth to help you make a better estimate of how old he is.
Your dog will (depending on the breed) stop growing as early as 8 months or up until the 18th month for giant breeds like the Great Dane.
