Miniature Schnauzers are little dogs with big hearts. They are known to be robust and spirited with wiry coats that come in three distinct color patterns. These are salt and pepper, black and silver, and solid black.

As a dog parent or prospective dog parent of a miniature schnauzer, a miniature schnauzer growth chart will be helpful, to monitor their growth.

Miniature schnauzers are usually around 12 to 14 in height at adulthood, and they were bred from the standard schnauzers, with which they share many similarities. They have bushy beards and eyebrows making them appear almost human-like.

Miniature schnauzers are sturdy despite their small size, and they enjoy high-energy activities. They are also home and family-oriented because they are excellent watchdogs who adapt to apartment life or large spaces. They also take training well.

Miniature schnauzers usually attain their full size at 12 months of age, which is around two months later than the average rate for dogs of that size. They should make the switch from puppy food to adult food at this time.

As their name suggests, miniature schnauzers are admittedly small, especially when compared to other schnauzers and other breeds.

Adult male and female miniature schnauzers normally weigh approximately 13 to 15 pounds and stand at 12 to 14 inches in height.

Miniature schnauzers usually have increased caloric needs as puppies. When they are about 12 months of age, their caloric should begin to match adult dogs.

The Miniature Schnauzer weight chart below displays the relative size of your miniature schnauzer’s and weight throughout the stages of development. If your dog’s weight is not exactly the same as the chart, there is usually no need for alarm as every dog is different.  

We can’t give a definite determination of the adult size of a puppy. The Miniature Schnauzer growth chart gives you an estimate of your puppy’s adult size based on the standard at that age.

However, remember that if you find your miniature schnauzer’s weight is a lot less than on the chart, you need to look at his overall health and wellbeing. 

You can relax if your miniature schnauzer’s weight is a bit more than any of the numbers in the chart. If he has a few extra pounds over the stated range it is perfectly acceptable, not all miniature schnauzers may fall within the established range.

It is advised that you always check with your veterinarian if you ever have doubts and notice anything peculiar.

Birth – 2 Weeks 

When your Miniature schnauzer puppies are just born, they are in need of their mother’s milk and warmth.  Their eyes are still closed, and they will spend most of their time nursing and sleeping until they gain their strength.

Their senses of touch, smell, and taste are present, but they can’t yet hear or see. Moreover, because of their undeveloped muscles, they can’t yet walk. They will weigh between 4 and 9 ounces and will be about 3 to 7 inches long at birth, but they will double their birth weight in these first two weeks.

3 Weeks – 12 Weeks 

At this time, your Miniature schnauzer will begin to use his sense of hearing and open his eyes. He will begin to gain muscles that are sturdy and allow him to stand up, play with his siblings, run, and bark. His teeth will also start to appear.

As his eyesight grows, he will slowly start to be informed of his surrounding conditions as well as get control over his bowel movement and bladder. At 2 months old, puppies will again double their size and weigh about 3 to 5 pounds.
