Predict how big your dog will get using a puppy weight calculator
A puppy weight calculator like the one above is supposed to give you an estimate of what your pup is going to weigh once fully grown.
You should note that the results you get from the puppy weight calculator will not be completely accurate as it is a tool to help you make a prediction. It is, however, essential in the planning for your puppy.
This is helpful in knowing how much space the dog will need.
The puppy’s weight is going to be affected by several factors such as;
- Amount of exercise
Can I use my puppy’s paws to predict the weight?
You can also use your pup’s paw to make an estimate of how big he will get. This may not be as accurate but usually larger paws will mean that your pup is going to be taller and weigh more and smaller paws will mean the pup will grow up to be shorter and lighter.
However, as I mentioned above this is not entirely accurate as there are some large dog breeds such as Ridgebacks that have small paws. Consequently, there are also smaller breeds such as Basset Hounds that have larger paws.
When does a puppy stop growing?
Large, giant, and medium-sized dogs take about 12 to 24 months to reach maturity while smaller ones should be fully grown by between 9 and 12 months.
Some toy dog breeds can even take only 6 months to reach their full weight.
So, is breed the only factor that affects the size of a dog once fully grown? No. There are other factors that come into play when as far as a dog’s weight when fully grown is concerned.
These factors are;
- Desexing age.
- Exercise and other environmental factors.
- Weight of the parents.
- Litter size.
Calculate your pup’s weight by breed
There are a couple of things that can guide you to predict the size of your pup other than using the puppy weight calculator.
The breed of your puppy is one of them.
A newborn puppy will double its weight after the first week and gain about 5% of its weight every day after the first week.
By 6 weeks of age, smaller dog breeds gain about 6 ounces per week while larger breed like the Bernese Mountain dog can gain up to 2 pounds and 5 ounces every week.
Large and medium-sized breeds
Large-sized dog breeds take longer to reach full maturity with the fastest growth period being between 0 and 20 weeks age. Medium-sized breeds take a shorter period to reach their full weight and have their fastest growth rate in the 0 to 15 week period.
For these dogs, you need to wait until the puppies are about 14 weeks old before you make any weight predictions.
Other than the dog weight calculator above, you can also make the weight estimate by calculating using the formula below. This might be slightly complicated.
What you do is that you take the puppy’s weight at 14 weeks, double the weight, and add half of the weight at 14 weeks get an estimate of how much the puppy is going to weigh when fully grown. The formula is as follows;
(Weight at 14 *2) + (weight at 14 weeks/2)
For example, if your puppy weighs 10 pounds at 14 weeks. This will be (10 * 2) + (10/2) which means that the pup will weigh about 25 pounds once he is fully grown.
You can also use your puppy’s weight at 6 months of age to make an estimate of the weight. At 6 months, a medium-sized dog breed will have reached a third of what he is going to weigh on maturity.
For larger breeds like Great Danes, the 6-month period is when they are about half of what they are supposed to weigh.
Small and toy dog breeds
Small and toy breeds grow the fastest at the age of between 0 and 12 weeks.
For these dogs, you need to wait until they are about 6 weeks old before doing the weight calculations.
You simply need to take their weight at this period double it then double it again.
(weight at 6 weeks * 2)*2
Age at desexing
Desexing is the removal of part or the whole of a dog’s reproductive parts. In males, it is known as neutering and in female dog’s it is known as spaying.
Neutering and spaying dogs also affect their size.
When you remove your puppy’s hormones, their bones may not receive the message that they need to stop growing. This means that they continue to grown past the time when they are not supposed to, resulting in a taller dog.
Doing this may, however, lead to some development complications of the orthopedic tissues and joint alignment.
It is also worth mentioning that you should never desex your dog if it is not a professional doing it.
Nutrition and feeding
What you feed your dog greatly affects how big he gets.
But puppies start to feed once they are born and their mother’s milk is very important. This milk (colostrum) contains fats and proteins that are important for the development and growth of newborn pups.
The lack of this milk can significantly stunt their growth.
During the weaning period, these puppies will need to be fed on a high-quality diet to meet their nutritional requirements.
Gender of your pooch
Sex affects the size of dogs and because of sexual dimorphism male dogs grow to become bigger than their female counterparts.
This difference in size is highly noticeable during the early stages of the pup’s adolescence.
If you would want to have a canine friend to be smaller then you should get a female puppy or vice versa.
Exercise and the environment
When you over-exercise your pup, you may cause damage or injury of their ligament and skeleton which could impede their growth.
Exercise is important for a developing puppy but overdoing it is disastrous.
Smaller dog breeds tend to have larger litters.
Over the course of time, the size of your litter is going to affect their growth.
Meet the parents
Meeting the parents of your puppies is your best chance at knowing what the size of your dog is going to be.
Your puppy is most likely going to take after the parent’s size mainly due to genetics.
