Because it is sweet and to most people it smells good. It is caused by the mother's milk and after a long period of time when the puppies keep drinking it, their breath starts to smell like the milk. unfortuenetly the sweet smell of puppy breath does not last forever it goes away after a few weeks, when you started to feed your puppy some dog food which is why adult dogs have horrible smelling breath. Also another thing is puppies, they have less bactiria in their mouths and are cleaner then an adult dogs mouth.
