My darling little man is going through some serious teething right now! He is a little over 4 months old, and we lost 3 puppy teeth in last 2 days ( that I know of for sure). Along with the non-stop chewing, he is drooling a lot (while chewing), his eyes are weeping (there are even visible tear stains which seem to have developed overnight) and last night and this morning his stool was loose. Is this all normal teething stuff? Flynn is my first pup since I was a kid, so I really can't remember the teething bit.
