Shih Tzu Puppy Weight Chart

A Shih Tzu Puppy Weight Chart can often be helpful if you want to estimate just how big your puppy will get.  It is generally accurate for other small breed dogs but not medium, large or giant breeds.  

Wonder how big your Shih Tzu will get?  Use this Shih Tzu Puppy Weight Chart to estimate the adult size of your puppy. The chart is more accurate for Shih Tzu dogs, but it can be used to estimate the adult size of most toy and small breed dogs.   Remember that this is just an estimate and that other factors can influence the puppy's growth.  These factors can include:

  • How Active the Puppy is
  • How much exercise the puppy receives
  • How much the puppy eats
  • The overall health of a puppy
  • The size of the parents

Perhaps the best overall indicator for adult size in puppies is their parents.  You will never get a genetically tiny Shih Tzu from two parents who weight 14 pounds each.  That is not to say that there could be a tiny puppy in the litter, just less likely.

In my personal experience, I have found that it is possible for the smallest puppy in the litter (the runt) to catch up to his litter mates and often pass them in size.  Sometimes puppies are born smaller than others due to their location in the womb. 

Other times, these small puppies are just genetically small.  If you are interested in reading more about small Shih Tzu puppies, I encourage you to read our article on Imperial Shih Tzu Dogs.  At Miracle Shih Tzu, we do not deliberately try to produce smaller and smaller dogs, but it does happen from time to time.  As we use smaller sized parents, our puppies generally get smaller, but as of this writing, we haven't produced any super small teacup size Shih Tzu.  Remember, the American Kennel Club (AKC) states in their standard for the Shih Tzu breed, dogs should be between 9 and 16 pounds.  For more information on the Shih Tzu standard, visit the American Kennel Club website.
