Why do dogs' eyes glow? Some glow red, while others glow green.

Dogs' eyes are not light sources, and they can't shine by themselves. Dogs' eyes glow at night because of their special structure, which can reflect light, just like a mirror. Dogs have larger pupils than humans and can receive more light in a short time, usually five times as much as humans.

The dog's eyes have a reflective layer. Whenever the surrounding environment gets dark, the eyes will automatically reflect the surrounding light, so that the surroundings can be seen more clearly. The reflective layer is located at the bottom of the dog retina and contains green pigment, accounting for about half of the whole retina area. Because the light enters the eyes at different positions, the color of the light reflected by the dog's eyes is also different.

Precautions:

In feeding dogs, you can give them some dog food, vegetables and fruits, and you can also eat some digestible meat, such as beef and chicken, but you should pay attention to breaking the meat for dogs to eat.

In addition, there are some things that dogs can't eat, such as milk and onions, which can't be eaten by dogs, and it should be noted that foods such as chocolate should never be eaten by dogs, which is a deadly poison to fruits.

Be sure to take the dog to get vaccinated in time. After waiting for the dog for about 45 days, you can take it to get vaccinated. Remember not to take it to vaccinate too early, which will easily threaten the dog's life.
