Why are the soles of some dogs black and some pink?

The color of dog's sole is influenced by genetic factors and breeds. The soles of most dogs are black, which is caused by the mixture of various pigments in the skin. There are more black pigments than other colors. The pink soles of the feet indicate that the dog's skin lacks black pigment.

The color of the soles of some dogs will change according to age, protective measures and climate. For example, when dogs' feet are often exposed to the sun, they may become darker, while those feet that are kept indoors may turn pink. When the climate gets cold, the soles of dogs' feet may turn black to better absorb heat.

It should be noted that dogs with pink soles are vulnerable to ultraviolet rays because black pigments can provide protection. Therefore, the owner needs to apply special sunscreen to the dog to help protect the skin of the feet.

In a word, the color of the dog's sole is determined by many factors, such as heredity and environment, which requires the owner to give appropriate protection and care according to the specific situation.
