10 Surprising Puppy Facts
1. A Puppy’s Coat Color and Texture Can Change
A puppy’s coat undergoes noticeable changes in both texture and color as they mature.
Initially, puppies often have softer, fluffier coats that evolve over time. For instance, Poodle puppies start with soft, wavy fur that becomes denser and curlier as they grow.
This transformation in texture is a natural part of their development.
Similarly, the color of a puppy’s coat can shift significantly.
For example, Weimaraner puppies as seen in the video above are born with a tiger-striped pattern on their coats, which is quite distinct and different from their adult coats.
In the first few days the stripe pattern fades, and their coat turns into the solid, sleek gray commonly associated with the breed.
Other breeds, like Dalmatians, are born white and develop their distinctive spots as they age.
2. They are Altricial
Puppies are born as altricial beings, meaning they come into the world underdeveloped. Unlike some other mammals that can walk and see shortly after birth, puppies are born with their eyes and ears sealed.
They also do not have the ability to eliminate on their own, to walk or regulate their temperature. This necessitates a heavy reliance on their mother for warmth, food, and protection.

3. They Are Born With the Sense of Touch
The first sense that is developed in puppies is their sense of touch. From birth, puppies can feel and respond to the touch of their mother and littermates. Since they are born blind and deaf, this sense of touch is crucial for their initial navigation towards warmth and nourishment.
The tactile stimulation they receive from their mother’s grooming and cuddling is essential for their physical and emotional development too.
4. The Sense of Smell Comes Next
While touch might be their first sense, their sense of smell starts developing shortly after birth, rapidly maturing and becoming more refined. By the time they are a few weeks old, puppies can distinguish between various scents.
This sense continues to develop as they mature, becoming one of their most powerful and defining senses. Dogs rely heavily on their sense of smell for communication, hunting, and exploring their environment throughout their lives.

5. Young Puppies Don’t Wag Their Tails
Puppies begin to wag their tails around a month old, marking a development in their ability to communicate. Initially, their body language is quite subtle, but as they grow and interact more with their littermates and humans, they start expressing emotions like excitement and happiness through tail wagging.
This behavior is an important part of their social development and helps strengthen bonds with their pack and human caretakers.
6. Not All Puppies Are Born With Blue Eyes
While it’s common for many puppies, especially those from breeds with lighter coats, to have blue eyes at birth, the initial eye color can vary.
Some puppies might have darker eyes from the start, depending on their genetics. The blue eye color in newborn puppies is due to a lack of melanin, which develops as they age, leading to the eventual darkening of the eyes in most breeds.

7. Vaccination and Immunity
Puppies receive a crucial head start on health through antibodies found in their mother’s first milk, known as colostrum. This early form of nourishment is packed with immune-boosting substances that provide newborn puppies with a protective shield against various diseases during their initial weeks of life.
These maternal antibodies are essential, as they help keep puppies healthy until their immune systems are more developed and ready to respond to vaccinations. As puppies grow and begin their vaccination schedules, these antibodies gradually wane, making way for their own immune defenses to take over.
8. Distinctive Puppy Breath
Puppies have a distinctive, sweet-smelling “puppy breath,” a charming feature that endears them to many pet owners. This pleasant aroma is largely attributed to their diet of mother’s milk and the presence of enzymes in their developing digestive systems.
As puppies grow and begin eating solid foods, the unique scent of puppy breath fades, replaced by more typical dog breath.

9. Puppies need a lot of sleep
Puppies typically need 18-20 hours of sleep per day during their first few weeks of life. This high amount of sleep is crucial for their development and tends to gradually decrease as they grow older.
By the time they reach about six months of age, the amount of sleep they need usually decreases to about 12-14 hours a day, though this can vary depending on the breed and individual energy levels.
As they transition into adulthood, their sleep requirements align more closely with adult dogs, which generally need about 12-14 hours of rest per day.
10. Puppies Grow and Mature at Different Rates Based on Breed
Dog breeds vary widely in how quickly they grow and reach maturity. This difference in development rate can be clearly seen when comparing large breeds to small ones.
Take for example the Bernese Mountain Dog. This large breed typically reaches their full height by about 18 months of age, but they continue to fill out and gain muscle until they are around 2 to 3 years old. The delayed maturity is common in many larger breeds because it takes longer for their larger bones and joints to fully develop.
This is about the same time frame it takes them to fully mature mentally – meaning they maintain some puppy-like behaviors – such as playfulness and boundless energy for a longer period compared to smaller breeds.
In contrast, the Maltipoo, a small crossbreed between the Maltese and a Toy or Miniature Poodle, reaches its adult size much quicker.
Generally, Maltipoos are near their full adult size by about 9 to 10 months old. Due to their smaller size, the developmental stages happen in a condensed timeline, allowing them to reach maturity much faster than their larger counterparts. They tend to reach mental adulthood by about 12 to 15 months old.

That’s a wrap
