Bad breathe in human or
dogs, is a sign of something not right....I would let the vet know, its probably bad
teeth...bad
teeth stink in dogs...
Welcome to dog forum, please check in with your comments, plenty people here with very informative suggestions,....
And, bad teeth, dogs can get that easy....my female has bad teeth, and I thought I took excellant care, but each dog different...just the way it is sometimes..
Good luck...
