“While a dog’s nose can sometimes be an indicator of an illness, it’s not as reliable as other symptoms,” Earl explains. “The temperature of a dog’s nose fluctuates throughout the day. So, not all dogs will have a cold, wet nose, which many pet owners incorrectly think is the sign of a healthy dog.”
According to Earl, not all pet noses are created equal. An ill dog can also have a cold, wet nose, while a perfectly healthy dog can have a warm, dry nose. When dogs sleep, their noses tend to dry out, as they are not licking their snout quite as much.
It’s best not to put too much stock in the hourly state of your pup’s snout, so pet owners can breathe easy. “Just keep an eye on it and visit a veterinarian if anything seems out of the ordinary,” she advises.
