I failed fostering with Radar a little over 5 years ago. Ever since I've had him, he's had extremely BAD breath. I've done the teeth cleaning, minty treats, vet exams, etc. Nothing has exposed the reason for the green fog, and nothing appears to be wrong.
He acts fine, eats fine, etc. But, he's turned from spooky shy dog into super affectionate dog over the years and while I'm happy beyond belief at that, Oh. My. Word. His BREATH!
Any suggestions? (besides a gas mask?)
