My Ds is 3 months and 5 days, and the past few nights he has been extra hard to get to bed and quiet unsettled at times... hes just found his hands and always has them in his mouth and dribbling alot now.. i checked his gums and he seems to have a bumpy thing on his gum, just one where the K-9 sits... Could it be his teeth? I thought the front 2 are the ones to come out first? :-k
