Why does my senior pug have diarrhea, fishy breath, and keep licking?

Question

I have a 12 year old pug and for over a week he's had diarrhea, he's never been sick, he's had all his shots, but for the past year he's constantly licking with his head up as if to keep food down, eve when he hadn't eaten. He also has horrible fishy smelling breath and cleaning doesn't help. Pet's info: Dog | Pug | Male | neutered | 12 years and 2 months old | 14 lbs

Poor Diego! The diarrhea could be due to a number of causes including dietary indiscretion (eating something he should not have or isn't accustomed to), bacterial imbalance in his GI tract, a parasite, or inflammation of his colon due to stress. The chronic swallowing problem is more concerning for gastroesophageal reflux, a problem with his lower esophagus such as megaesophagus, or even potentially cancer. His bad breath could be due to persistent bacteria in the mouth, a tooth problem, or potentially related to his swallowing trouble. I recommend having Diego evaluated by a veterinarian for these issues. A fecal test would help to determine the cause of his diarrhea and how to treat it. The swallowing problem is something that will require an oral exam and possibly x-rays of his neck and chest or a more advanced swallowing study with contrast material. Or, your vet may recommend some medications if reflux is suspected. I hope this is helpful and you can find some answers!
