Find out your puppy's weight at birth and how old he is now. Generally, small puppies will double their weight by the time they are 2 weeks old. For example if your puppy is 2 weeks old and he was 2.5 ounces at birth, the estimated weight is 5 ounces by the time he is two weeks old. This is a formula based on estimates and does not account for a puppy's breed.
Calculate on average a doubling of the puppy's weight by the end of week 7 and 16 weeks old (four months old). Take the 5 ounces at the end of week two and double it up to end of week 7. This will be an estimate of 10 ounces. Take the 10 ounces and double it again up until week 16. This will give an estimate of 20 ounces by the time the puppy is four months old. Add an average of 5 to 10 pounds after four months old for the entire life of the puppy to estimate his adult weight.
The first 16 weeks can provide a reasonable estimate of puppy's weight. After the 16 weeks, weight gains are much slower. Remember that every dog and breed is different and that these numbers are only estimates.
Use online resources to find puppy's weight charts. There are many websites that provide free weight chart estimates. Find a breed specific chart to better predict the puppy's weight. If you own a Chihuahua, use a Chihuahua weight chart.
Weight your puppy periodically and compare it to the estimate in the charts. Check to see if the two measures are close and estimate the puppy's future weight gains.
Consult the veterinarian for more accurate prediction of your puppy weights. In addition to giving the puppy a checkup, the veterinarian can tell you how big your puppy will get by a certain age using the dog breed, charts and other attributes as guidance. Ask the veterinarian for proper nutritional instructions to maintain a healthy weight in your puppy.
How to Get Puppy Weight Estimates
Many dog owners wonder how big their little puppies are eventually going to get. This is an important consideration since some of us live in small spaces. Every dog, puppy and breed is different and how much weight a puppy is going to gain depends largely on eating habits and breeds. There is no sure method for obtaining a puppy's weight, but we can get estimates using some general guidelines.
