Q: My six-year-old German Shepherd's nose has become very dry and is all cracked. He is in good health otherwise — does anyone know why it would be cracked?
A: I've heard of dogs having dry noses when they are dehydrated so make sure he gets (and chooses to drink!) plenty of water. Also, just like cold weather saps our skin, chilly temperatures could have a negative effect on a dog, too. If he has other visible dryness — like on paw pads — it could be the sign of an illness or allergies, so double check with the vet to get a clean bill of health.
