Louie's breath was kinda bad when I first got him at 8 weeks, but then it cleared up and I didn't mind it at all, even when he started teething a month ago. Then, at about 5 months old, two weeks ago, it started smelling *really* bad, just plain nasty! Seriously, it's so awful! How long is this going to last, and what can I do? He always wants to lick my face and my hands and everything he licks smells nasty afterwards. I used to love to let him give kisses but now I have to kinda grin and bear it. I feel so bad!
