Why does my Jack Russell have stomach issues with every kibble?

Updated On September 23rd, 2025

Pet's info: Dog | Jack Russell Terrier | Female | spayed | 3 years old | 11 lbs

I would like to know why my 3 year old Jack Russell Terrier has food issues with Kibble. I think I've tried everyone of them on the market ....almost. I have tried everything from the best & high priced Holistic brands to the lower rated ones with always the same result. After feeding at least a 5 lb. bag she starts to have stomach issues. Bloating , looking swollen, refusing to eat, especially the morning meal. She is always weaned off one before starting another.

Food allergies can be very frustrating to diagnose since there are multiple ingredients that can cause a reaction. Consider an exam with your veterinarian. Discuss allergy testing, hydrolyzed diets, food elimination trials and antihistamine use during the visit. A food trial should last at least 6 weeks during which only the new diet should be fed. No treats, no table food, no other foods. Choose a food with a protein and carbohydrate source that Lucy has NEVER eaten before. This can be tricky but there are several prescription and OTC choices.
