Hi Everyone I am new at this. So bare with me. My 4month 2.2 pound Yorkie has this wierd internal cough. Its happens at night and when he takes naps. It almost sounds like Post nasal Drip. I feel bad for the little guy. My doctor says its from teething. His lungs are fine. But I am a little bit worried about this situation. Mr. Buttons(My puppy) doesn't seem bothered, but it interrups his sleep. Can Anyone Help with ADIVCE??Please..Thanks you!!! Barbara
