What is hot nose sign?

The hot nose sign is a physical indication of an animal's internal body temperature. It is commonly observed in dogs, cats, horses, and other mammals. When an animal is overheated or has a fever, their nose can feel warm or hot. This is because the blood vessels in the nose dilate, increasing blood flow and heat to the area. Conversely, when an animal is cold, their nose may feel cool or even cold to the touch. The hot nose sign is not always an accurate indicator of an animal's overall health, as there can be other factors that affect their body temperature. It is always best to consult with a veterinarian if you are concerned about your pet's health.
