What do you do when you see a dog with crazy eyes? Do you say “awwww, how cute!”? Do you assume the dog is having some kind of medical issue?

Or do you know just from a glance that the dog has probably experienced some trauma and will likely struggle for the rest of its life with PTSD?

How do you know which dog has been abused? And how do you know when the abuse isn’t something the owner did, but instead is an inherited condition?

For a decade, researchers at Tufts University in Massachusetts have studied canine domestication, or how and why dogs became domesticated over the past 10,000 years.

For their work, the Tufts team studied the eyes of many different dog breeds, and then mapped that information to the eye-shaped genetic regions responsible for the eye color and eye shape of each breed.

This approach revealed that dogs’ eyes evolved independently, and that eye shape and color were not inherited through the male line. In other words, it’s not possible for one dog to have a blue-eyed mate and a blue-eyed son, because the genes responsible for eye shape are in a different part of the chromosome than the genes responsible for eye color.

That means that if one eye of a dog is blue and the other is brown, then both eyes were born with brown eyes. So when someone says that a dog has “crazy eyes,” that means the dog in question likely inherited a mutation that causes an overabundance of melanin pigment in the eye.

What does that mean for you? It means that if you’re going to be a good foster parent, you’d better make sure your dog has the best vision possible, because your dog will need to see what is going on around him to survive.

When it comes to choosing a puppy, this can mean picking out dogs that are born blue-eyed, but whose parents have brown eyes. For example, many breeds of dog come from dogs whose parents came from one blue-eyed, and one brown-eyed ancestor. That means the puppies born from the parents have blue eyes, even though one of their parents had brown eyes.

This isn’t to say that a dog with brown eyes is defective or a lesser-quality dog, it just means that sometimes breeders use what’s called “selective breeding” to select for one trt and minimize any undesirable effects of another. That means if someone wants to minimize the occurrence of one problem in a breed — for example, if they are breeding only for dogs that are born with blue eyes — they will be breeding only dogs with brown eyes.

But not all breeds have that luxury, and as I discussed in my book, The Biology of Bones, some breeds are simply bred by the color of their eyes, which means all the puppies in that breed will share the same eye color.

The next thing to know about dog eyes: Dogs with blue eyes, like cats, have a lens that is made of a clear gel-like material (called the aqueous humor) that allows light to enter the eye and help regulate the temperature of the eyeball. But dogs with brown eyes, like wolves, have a lens that is much thicker than a cat’s, which means that light entering the eye is absorbed by the lens and cannot be used to regulate eye temperature.

The end result is that dogs with blue eyes are less likely to develop glaucoma, an eye disease that causes the fluid-filled sacs (called the eyeballs) in the eye to lose their fluids and become hard, and eventually cause blindness. In contrast, dogs with brown eyes are at risk of developing glaucoma at an early age, even in large breeds.

Here are some other things you should know about dog eyes.

When the light from the day goes down and the light from the moon comes up, the dogs with brown eyes have the most trouble seeing.

When it comes to dogs, the most common eye color is brown, so if you are breeding a dog, make sure the parents’ eyes are not the same color.

There are many breeds of dog that have brown eyes — breeds like Dalmatians, Poodles and Shetland Sheepdogs. This means that even though there are a number of breeds that come from dogs with blue eyes, many dogs will have a very difficult time if they are in a shelter and the shelter does not have a veterinarian to test the eyes of all the dogs they receive.

If you want to ensure that your dog is able to see in the dark, you can make sure that it has some form of vision correction. Many dogs have been known to wear sunglasses. If you see a dog wearing glasses, it is probably a great candidate for glasses because it’s been shown that dogs that can’t see in the dark are less likely to survive than dogs who can see well in the dark.

Finally, you should also know that the color of dog eyes can change as the dog ages. In general, most dogs begin life with blue eyes that slowly fade to brown as they grow older. But what about dogs that have blue eyes when they are puppies, but have brown eyes later in life? These dogs have inherited a gene that turns the blue eyes into brown eyes. The more generations that a dog has been bred with dogs with blue eyes, the more likely it is to inherit that gene.

A final word on eye color and dog breeds: Even though the most common eye color is brown in dogs, the gene for blue eyes is more common in some breeds than others. For example, German Shepherds have a much higher chance of inheriting blue eyes than, say, Chihuahuas, simply because so many dogs of this breed are bred to be blue-eyed. That’s not to say that a Chihuahua will not inherit the gene for blue eyes, but
