At What Age Does a Puppy Stop Growing?

If you have ever had a puppy, no doubt you have asked yourself at some point At What Age Does a Puppy Stop Growing?

Puppies usually will grow the most rapidly their first few weeks of life - starting out small enough to fit in the palms of your hands, then progressing to being big enough to start finding the food bowl, romping around with his or her brothers and sisters, and chewing on things he or she probably shouldn't be chewing on! From there, a puppy will continue to grow as it gets taller and longer.

At what age does a puppy stop growing depends highly on the breed of the dog. For example, a small puppy that only weighs 10-15 pounds in adulthood may stop growing by 6 months. A larger dog may need up until one year before the puppy stops growing. Other puppies may not stop growing until the puppy is 18 months or 2 years old! Puppies can also be much like humans in development: no two puppies are the same! You can have puppies from the same litter who may grow at different rates or have one that is significantly larger or smaller than the other puppies.

Usually by the age of one year old will you have a good idea of just how big your puppy will get and if the puppy is still growing. If your puppy is over two years old, it's quite likely you no longer refer to the puppy as a puppy but an adult dog!

A puppy's diet can also affect how large a puppy will get and the overall size of the puppy. A puppy who eats a well balanced diet of healthy puppy and dog food and gets moderate activity will likely be lean and fit. A puppy that generally overeats and does not get a lot of exercise and activity however might be much larger than other puppies of the same age and breed and may continue to grow.

To get the best results on determining at what age your puppy will stop growing, you should ideally speak to your trusted vet, who should be able to show you how the puppy is doing devlopmentally and what you can expect in terms of the puppy's growth and behavior specifically to the breed of the puppy.
