What food do you feed? Since you mentioned your other dog having bad nails as well, it can be a sign that the nutrition isn't right.
I agree with Lisa, if he is licking it then its probably bothering him. Can you trim down the cracked part at all? Usually when a nail splits it needs to be cut at the end of the split to prevent it from going further. Depending on how far the split is, thats why the dog might need anesthesia for it to be done.
