Why is my dog vomiting and having yellow diarrhea on raw food?

Updated On September 23rd, 2025

Pet's info: Dog | Australian Shepherd | Male | unneutered | 2 years and 9 months old | 50 lbs

My dog has been puking a lot and sometimes we have to starve him for a day to readjust. His bowels are bright yellow and he get diarrhea often (even since he was a pup). He is on a raw pet food diet. Is the food the issue here? we also live with many small children that throw things he can swallow easily. Please help me!

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Poor Azrael! Yes, it very likely is the food. A lot of dogs tolerate raw diets but there is a higher risk of food borne pathogens like Salmonella. But regardless of raw vs commercial dog food if he has a food allergy to the protein source (chicken, etc) he will vomit, have diarrhea, lose weight. He may also have inflammatory bowel disease which is usually treated with a special diet as well as steroids. Another possibility is pancreatic conditions like Exocrine Pancreatic insufficiency. EPI is common in German Shepherds and it is when the pancreas doesn't produce the appropriate digestive enzyme and it needs to be supplemented. I would deworm him, do general blood work, do a B12/folate/TLI/PLI test, change his to a prescription hydrolyzed diet like Royal Canin HP or Ultimino or Hill's Z/d or Purina HA. Give him 2 months on that diet to see if his issues resolve. I hope this helps!
