My dog ate rancid food. What should I do if he gets sick from it?

Updated on September 23rd, 2025

Pet's info: Dog | Jack Russell Terrier | Male | neutered | 11 years and 1 month old

My dog ate rancid dog food. It was very dark on the surface and red underneath. Seems the packaging in the box had been opened for a while. t’s been an hour or so and he seems perfectly fine (still hungry too - asking for his treats) I do worry he may get very sick though as the dog food smelt foul. I can not afford emergency vets unless absolutely necessary. Any advice you can give would be great

Your dog will probably be ok, as dogs often eat stinky food they buried a long time before eating it. Watch your dog for vomiting and diarrhea and when this happens, take Russ off food for 12 hrs., then feed him some bland food such as boiled white rice with boiled boneless white chicken meat in several small feeds over the day. The next day start replacing small portions of the rice mix with his regular food. Do this for about two days until all the rice and chicken is replaced with his regular food. If he still vomits or has diarrhea, you need to take him to your vet for treatment.
