Updated on September 23rd, 2025

Can feeding multiple protein sources at once cause G.I. Disturbance, or is this not a problem?

This is a great question and the answer depends on the dog you are feeding and whether or not they have a food intolerance or allergy.

Typically, in a normal dog, feeding different protein sources to should not cause any problem. If the food is switched too quickly however, it may cause some GI upset like diarrhea and vomiting. If you are feeding a mixture of the proteins all at once this will probably cut down on tummy upset because you aren't switching back and forth.

The only problem I can forsee is if the dog has an allergy to one of the proteins you are feeding her. Food allergies typically cause problems with the skin, ears and anal glands.

I hope this helps. Thanks for using Petco Pet Education Center, formerly Petcoach. Best of luck.

    Typically no. Actually, feeding the same protein source is best for your dog. If you continually change they can get gastrointestinal upset. It isn't very common for dogs to be allergic to food, although it can happen.
