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:
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.
Simply going by the size of the parents is not enough. Your puppy shares part of the DNA that is provided by the parents, but also maternal and paternal grandparents. As you go farther back into the pedigree, the ancestors have less effect on the current generation, but there is still that trace DNA.
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 are born 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.
Shih Tzu that are below the standard size are generally healthy but may have a smaller bone structure. Assuming that the small Shih Tzu is of normal weight and muscular, it is still important to assure a healthy lifestyle. There are some precautions that should be noted.
Everyone wants to know how big their Shih Tzu puppy is going to be when they become an adult. A Shih Tzu dog obtains its adult weight between 9 and 12 months. Some will still gain weight especially if they take in more calories than they burn.
The growth rate in this breed does not uniform, but rather there are periods where the puppy grows faster than others. The first month, for example is a period of rapid weight gain, but once the puppy reaches 8 months or so, their weight gain slows.
You can get an estimate of what size the puppy will be as an adult by using a traditional Shih Tzu Puppy Weight Chart. Often these figures end up being less than accurate.
|Age of Puppy||Estimated Weight of Puppy|
|1 Month||Puppy is 10% of her Adult Weight|
|2 Months||Puppy is now 20% of her Adult Weight|
|3 Months||Puppy is now 1/3 of her Adult Weight|
|4 Months||Puppy is now approximately 1/2 of her Adult Weight|
|5 Months||Puppy is now approximately 2/3 of her Adult Weight|
|6 Months||Puppy is about 83% of her Adult Weight|
|7 Months||Puppy is about 96% of her Adult Weight|
|10 Months||The Puppy is now 100% of her Adult Weight|
It is often better to get a range of weights rather than an actual weight based on the size of the parents. The following weights are estimates.
Shih Tzu owners who also have raised children know how important it is to tract weight and height measurements at each well-child visit to the pediatrician.
At present, we are not that sophisticated to be able to predict growth curves within the breed, but many Shih Tzu breeders (myself included) enjoy hearing from previous puppy buyers who will reveal their puppy's adult weight. Over the years, one can begin to predict with more and more accuracy what a puppy will be as an adult. With that said, however, there are always exceptions.
For this Shih Tzu puppy weight chart, we took the weight at a specific age and extrapolated the adult weight.
