Is it tru that if my dogs nose is warm he's sick?

Its kind of one of those things where if he has a fever his nose is warm, but if his nose is warm it doesnt mean he has a fever. So many people think that because their dog's nose is dry and warm that he is sick, and thats not necessarily the case. If your dog is eating, drinking, and acting normal, then there is no reason to rush him into the vet because he has a warm, dry nose. A normal temp for a dog is 101.5-102.5 so they will feel warm to the touch anyway, so if your dog is acting normally then dont worry.. he's fine.
