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 idea of what your pup is going to weigh once he is fully matured.
Many people ask the question of how big their dog is going to get.
Getting the exact weight is not possible but what you can get is a prediction.
What you feed your dog, the breed and the amount of exercise he gets are some of the factors that can affect his weight.
This is helpful when you want to know how much space he is going to need.
First, you need to understand when your puppy will stop growing.
When does a puppy stop growing?
Large, giant and medium-sized dogs take about 12 to 4 months to reach maturity while smaller ones should be fully grown by the age of 12 months.
Some small dog breeds can take only 6 months to reach maturity.
So, is breed the only factor that affects the size of a dog once fully grown, no. There are other factors that you need to put into consideration too.
These factors are;
- Gender of your pooch.
- Desexing age.
- What you feed to your dog.
- Exercise and other environmental factors.
- Parent breeds
- Size of the litter
Estimating the weight of your pup by using 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.
Newborn puppies double their weight after their first week. After that week is over their weight increases by 5 to 10% after every day.
By the time they reach about 6 weeks of age, the large and smaller dogs start to gain weight differently. Smaller dog breeds gain around 5 oz per week while larger dog breeds gain about 2 pounds and 5 oz per week.
Large and medium-sized dog breeds
As we have mentioned above, you might have to wait a little longer for your large-sized dog breed to reach full maturity.
For these dogs, you need to wait until they are around 14 weeks old to make any predictions.
This might be a little bit complicated. So, what you do is that you take the puppy’s weight at 14 weeks of age, double it and add half of what he weighs to that.
(Weight at 14 *2) + (weight at 14 weeks/2)
Let us say that for example your pup is now 14 weeks old and he now weighs 15 pounds. This will be 15 + 15 + 7.5 which means that he will weigh about 37.5 pounds once he is fully grown.
The 6-month age period is something else that you can look at when you are doing these calculations. This is the age when your dog is going to weigh about 2/3 of what he is supposed to weigh.
For giants dogs like the Bernese Mountain dog that 6-month period is when they are about half of what they are supposed to weigh.
Small and toy dog breeds
For these dogs, you need to wait until they are about 6 weeks old to start predicting their size.
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 (puppy weight calculator)
The neutering of dogs also affects their size.
It is said that when you remove your dog’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.
Doing this may however lead to some development complications of the orthopedic tissues and joint alignment.
Never carry out desexing of your puppy before you consult your vet.
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 contains fats and proteins that are important for the development and growth of newborn pups.
The luck 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.
If you would want to have a canine friend that is smaller then it would be better if you went for a female puppy.
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.
