Myth #3—A warm nose means your dog is sick.
The reality: If you want to figure out if your dog’s ill, look for signs of lethargy, loss of appetite, coughing, vomiting, diarrhea, and other signs of distress. If a dog’s nose is cool, it may have just had a drink of water. If it’s warm, they may have been out in the sun. You can also feel the dog’s head with your hand—although, a dog’s normal temperature is 101 to 101.5, so it will feel slightly warm to a human.
