Ask your brother! It could be that your brother was once told that a dog's wet nose was a sign of good health. Communicate!
Well, the answer is if you touch it's nose very gently and blow air.
Dogs and cats should have wet noses. A nose that is slightly wet to the touch is a sign of a healthy dog. A dry nose indicates a problem, as does an overly wet or dripping nose.
No two nose prints are alike a dogs nose print is like our finger print.
The coldness or dampness of a dog's nose is an indication of his activity level and it's not about his health condition. When dogs have been active their nose will turn cold and wet. When dogs are sleeping or resting, their noses will feel warm and a bit dry. To know if a dog is sick, you need to take it's temperature.
