I use puppy wipes too...keep them in her puppy bag (diaper bag)
She eats breath mints daily and I brush her teeth every day (puppymint)
I think my hubby dried her off with a mildewy towel last night..that has to be it..we have had rain for a week and there was a towel out there on the patio that we had been using..it must have gotten damp and mildewy..its not her breath or her..its an attached odor...lol..Bath took care of it..its gone now..

I also keep spray..Very Berry by Crazy Pet - for in between baths..
Thanks for all your help~
