Predicting exactly how big your little ball of fur will be when it grows up is not an easy task, but it can be done.
However, it depends on a variety of factors including breed, nutrition, health and energy level, so it is never a guarantee, especially if your pup is a mixed breed.
The Apple Doesn’t Fall Far From The Tree
First, take a look at your pup’s parents. When it comes to pooches which are pure in breed, look at the adult weight of the dame and sire, as this will give you a pretty good idea what to expect.
If you do not have the access to the parents and their information, call a local breeder to inform about the average adult weight of the particular breed.
If your puppy happens to be a mixed breed, go to a professional (local veterinarian or breeder) and ask what breeds he or she believes your puppy is a descendant from.
Also, ask the vet to try and classify your pup in one of 5 standard sizes: toy, small, medium, large or giant breed.
Predicting The Weight
Take this number and double it again to receive your puppy’s estimated weight. (For instance, if a dog weighs 1 pound at 6 weeks, he would have an estimated adult weight of 4 pounds, and so on).
When it comes to medium and larger breeds, take their weight at 14 weeks and double it. Then add half of the original weight. (For instance, if your puppy weighs 25 pounds at 14 weeks, double this to 50 and then add 12.5 for an estimated adult weight of 62.5 pounds).
