When Is A Puppy Full Grown?

The worst part about trying to pinpoint when a puppy is full grown is that there is no 100% across-the-board, correct answer. Every single puppy is different, as are humans, and growing is different for each of them. However, there are some solid, very general guidelines one can go by to have an idea of when your pup is all grown up.

It is important to remember that small dogs grow much faster than larger breeds. Some large breeds can take up to two years to reach their full, adult size. Pekingese or Pugs can reach their full size by about nine months. A good general rule of thumb is that a puppy reaches his or her maximum size in the twelve to eighteen month range. Again, this can very from breed to breed and dog to dog. By the end of two years, you should have yourself a full grown dog.

Generally, a puppy’s size develops a bit faster than the rest of him. Check the web, your local library, or your veterinarian office for information on the expected full size of your puppy. These should only be used as very general guidelines. Often the most lovable pups can be the “runts” of the litter and never reach the full expected size.

A lot of puppies will have a fully developed skeletal structure before their internal workings are fully developed. The brain as well as other vital organs like the lungs and heart will be well behind the skeletal structure in terms of development. This means that rough horseplay and physically taxing medical treatments should be invited until you know for sure that your puppy is fully grown. For example, your veterinarian may recommend waiting to spay, neuter, or breed the puppy. Always listen to your vet, as he or she can monitor that internal development. Though one should never hit or physically punish a puppy, these things can be especially dangerous even deadly in this delicate time of growth. When considering your puppy’s health, remember that pet insurance or dog insurance can help in times of need when finances will be the least of your concerns.
