Is my dog's diarrhea & picky eating from kennel cough antibiotics?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed | Male | neutered | 4 months and 6 days old | 10 lbs

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.
