Why is my puppy refusing his kibble after starting medication?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Large (61lb +) | Male | neutered | 7 months and 25 days old | 115 lbs

How can I help a puppy who on and off will be excited to eat kibble plain and then sometimes he turns his nose up to it. this Saturday he started turning away from the bowl but before he was good. We have struggled with the Vet and finding the right dry food that wasn’t hurting his stomach but also that he liked. The vet assumed it was an allergy and to switch. So i switched to Royal Canin 2 months ago it was fine. Now I’m treating him for bacterial infection since Saturday night. Is this why?

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Poor Bear! Medications can mess with an already sensitive stomach. So if his decrease in appetite matches when you started medications for his skin that is likely the reason. See if adding warm water to the dry food helps or a tablespoon of canned food with in the same brand will get him to eat. Hopefully when his skin is cleared up and the medication is over he will resume eating normally. I wish you the best
