Lately my dog has had really bad breath. I mean toxic! ?

bad breath
StirItUp asked:

i’ve checked her teeth and gums and can’t see any problems. I have a vet appointment with her for December to have her teeth cleaned.
she’s 1/2 poodle and my neighbor has a poodle and says it can be common with the breed. Is that true?
She said there are some water additives, etc. Any suggestions?
