As a new puppy owner, it’s natural to wonder what your puppy will look like as they grow up. One aspect that many people focus on is the color of their puppy’s eyes. Blue eyes in puppies can be particularly striking, but many pet owners wonder whether these blue eyes will stick around or change as their puppy gets older. In this article, we’ll take a closer look at the question of, “Will my puppies’ eyes stay blue?” including what factors affect eye color and when you can expect your puppy’s eye color to stabilize.

What Causes Blue Eyes in Puppies?
The stroma contains cells that produce melanin, which gives the iris its color. When a dog has blue eyes, the stroma contains very little melanin, which causes the iris to appear blue or blue-gray.
It’s important to note that blue eyes in puppies are not a guarantee of a dog’s permanent eye color. When puppies are born, their eyes are usually closed and their irises have not yet developed any pigment. It’s not until they are about six to eight weeks old that their irises start to develop melanin and their eyes begin to take on color.
As the irises develop, they may start out blue or blue-gray, but they will gradually start to change color as more melanin is produced. By about three months of age, most puppies’ eyes will have stabilized to their permanent color.
However, there can be some variation in this timeline. Some puppies may start to develop pigment earlier or later than others, which can affect the timing of their eye color change. Additionally, certain factors such as breed and coat color can also play a role in the development of eye color in puppies.
For example, some breeds are more likely to have blue or blue-gray eyes than others. Siberian Huskies, for instance, are known for their striking blue eyes. Australian Shepherds and Border Collies are also breeds that are more likely to have blue or blue-gray eyes.
Coat color can also affect eye color in puppies. For example, dogs with a merle coat pattern (a mottled or speckled coat with patches of lighter and darker colors) are more likely to have blue or blue-gray eyes. This is because the merle gene not only affects coat color, but it can also affect the development of pigment in the iris.
Once a puppy’s eyes have stabilized to their permanent color, it’s unlikely that they will change again later in life. However, there are a few situations in which a dog’s eye color can change or appear to change.
One such situation is disease or injury. In some cases, a dog’s eye color can change as a result of disease or injury. For example, a condition called uveitis can cause the iris to become inflamed and change color. Additionally, some dogs may develop cataracts, which can cause the eyes to appear cloudy and change color.
Another situation in which a dog’s eye color can appear to change is aging. Just like humans, dogs can experience age-related changes in their eyes. As they get older, their eyes may become cloudy or develop a bluish haze, which can change the appearance of their eye color.
Finally, it’s worth noting that a dog’s eye color can appear to change depending on lighting and surroundings. For example, a dog’s eyes may appear bluer in bright sunlight or in front of a light-colored background, while they may appear darker in dim lighting or against a dark background.
When Do Puppies’ Eye Colors Change?
Most puppies are born with blue eyes, regardless of their eventual eye color. This is because their eyes haven’t yet developed enough melanin to give them their permanent eye color. Over the next few weeks and months, the puppy’s eyes will gradually begin to develop more pigment, which will determine their eventual eye color.
For example, the Siberian Husky is a breed that is well-known for its striking blue eyes. These dogs often have blue eyes as puppies, which can remain blue into adulthood. However, other breeds such as Golden Retrievers and Labrador Retrievers are less likely to have blue eyes, and their eyes will usually change to brown or another color as they mature.
Coat color can also play a role in determining a puppy’s eventual eye color. Dogs with a merle coat pattern, for example, are more likely to have blue eyes, regardless of their breed. This is because the gene that causes the merle pattern also affects the development of pigment in the eyes, resulting in a higher likelihood of blue eyes.
It’s also worth noting that not all blue eyes in puppies will eventually change to a different color. Some dogs, particularly those with certain breeds or coat colors, will retain their blue eyes into adulthood. In these cases, the lack of melanin in the iris is simply a part of the dog’s genetic makeup, and it does not indicate any health issues or problems with their vision.
In general, most puppies’ eyes will start to change color when they are between six and eight weeks old. This is when the melanin in their irises starts to develop, and the blue color begins to fade. By the time the puppy is around three months old, their eyes will usually have stabilized to their permanent color.
However, it’s important to note that there can be some variation in when puppies’ eyes change color. Some puppies may have already started to develop their permanent eye color by six weeks, while others may take a little longer. Additionally, some breeds of dogs are more likely to have blue eyes than others, which can affect the timing and stability of their eye color changes.
Regardless of whether a puppy’s eyes eventually change to a different color or remain blue, it’s important to care for their eyes properly. This includes regular check-ups with a veterinarian, cleaning their eyes when necessary, and avoiding exposure to harmful substances that can damage their eyes.
What Factors Affect Eye Color in Puppies?
While the development of eye color in puppies is largely determined by genetics, there are a few other factors that can affect when and how their eyes change color. Here are a few things to keep in mind:
- Breed: Some breeds of dogs are more likely to have blue eyes than others. For example, many breeds in the “spitz” family, such as Siberian Huskies and Alaskan Malamutes, are known for their striking blue eyes. Other breeds, such as Australian Shepherds, can also have blue or partially blue eyes.
- Coat color: Eye color is often linked to coat color in dogs. For example, many white or merle-coated dogs will have blue eyes, regardless of their breed. This is because the same gene that causes the light-colored coat also affects the development of melanin in the iris.
- Genetics: Ultimately, the most important factor in determining a puppy’s eye color is genetics. Eye color is a polygenic trait, meaning it is determined by multiple genes. However, the exact combination of genes that determines eye color can be difficult to predict, even for breeders.
Will My Puppies’ Eyes Stay Blue?
Once a puppy’s eyes have stabilized to their permanent color, it’s unlikely that they will change again later in life. However, there are a few situations in which a dog’s eye color can change or appear to change:

Conclusion
In conclusion, while blue eyes in puppies can be striking and beautiful, they are not always a guarantee of a dog’s permanent eye color. Most puppies’ eyes will start to change color when they are between six and eight weeks old, and their eyes will usually have stabilized to their permanent color by three months old.
However, there can be some variation in this timeline, and certain factors such as breed and coat color can affect the development of eye color in puppies. Once a puppy’s eyes have stabilized to their permanent color, it’s unlikely that they will change again, although there are a few situations in which a dog’s eye color can appear to change. Ultimately, the most important thing is to love and care for your puppy, no matter what color their eyes end up being!
