Ziggy is currently on chloramphenicol for kennel cough (day 6 of 14). He had torbutrol cough suppressant for 3 days. So far, the coughing has stopped. He suddenly developed diarrhea and is pickier than usual about eating. Could this be a side effect of the antibiotic or something more serious? I plan to take him to the vet first thing tomorrow, but I am a concerned now. Also, he has chest X-rays which showed no significant infections.

This very well maybe a side effect is the antibiotic. If he is still eating and drinking and there is no blood in the stool, you can add a canine pro biotic to his food to see if that helps. You can also try boiled chicken and rice as a diet. If it get worse and he stops eating I would stop the medication until you can get him seen.

It's probably either something they ate or a gastrointestinal infection. you can try feeding them boiled chicken and rice for a couple days and see if there is an improvement, if not you will need to take them to the vet as they may need antibiotics.

Unfortunately the kennel cough vaccine is not 100% guarantee that your dog couldn't get kennel cough. It's sort of like the flu vaccine in which it will help prevent but doesn't protect against all strains. Therefore if the coughing continues I recommend discussing it with your veterinarian however kennel cough is usually self-limiting disease, meaning most dogs clear the infection on their own without antibiotics. It maybe your dog just needs time to adjust to the new food. If the diarrhea becomes bloody or does not improve after a day or so that it could indicate something else is going on and medication maybe need it.

No, it's not likely to be related to the vaccine. It sounds as Charlie is suffering from a gastrointestinal condition, possibly an infection. it could also be due to ingestion of a foreign body material. i would recommend taking him to the vet the first chance you get, he will need to be checked first, if the vet thinks it's a simple gastrointestinal infection he will need an anti vomiting injection, antibiotics and a special food for a few days in order to get better.
