10 Best Dog Foods for Autoimmune Disease in 2026: Vet Approved Reviews

Like humans, dogs have an immune system to protect them from illness and disease. When this natural defense system can’t distinguish between foreign cells and the body’s own cells, it can turn on itself.

An autoimmune disease is when the body’s immune system attacks healthy cells. The causes of autoimmune diseases are not fully known or understood, but genetics and environmental conditions may play a role.

Diet alone can’t cure autoimmune diseases or treat the symptoms, but the right diet can provide support while your dog is undergoing treatment. It’s important to work closely with your vet to choose the appropriate diet for your dog, but we have compiled a list of reviews of the best dog foods for autoimmune diseases and options to discuss with your vet.

Disclaimer: The foods reviewed here were chosen because they have certain characteristics that might help with some of the causes or consequences of this medical condition. However, they are not a medical treatment or a substitute for medical treatment. Keep in mind that each medical case is different and what works for some pets may not work for others.

Common Autoimmune Diseases in Dogs

In dogs, autoimmune diseases are somewhat rare. The symptoms and complications can vary by type, but the common thread among them is that the immune system is in “overdrive” and attacking healthy cells.

Here are the most common autoimmune diseases:

• Pemphigus complex: A group of five autoimmune conditions that form small blisters in the mouth and mucus membranes. They commonly affect the eyelids, lips, nostrils, and anus.
• Bullous pemphigoid: A type of immune disease that involves itchy, large welts that appear before or after the formation of blisters. The blisters may occur in the mouth and mucus membranes, armpits, and groin.
• Systemic lupus erythematosus: This is an example of a multi-systemic autoimmune disease that can mimic other diseases. It can involve a wide range of symptoms like stiffness in the legs, blood abnormalities, and symmetrical dermatitis.
• Myasthenia gravis: This is a disease that causes a malfunction in the transmission of signals between nerves and muscles. Dogs experience extreme weakness, excessive fatigue, regurgitation of food and other signs.
• Type 1 diabetes mellitus: A common type of diabetes that occurs in dogs, type 1 diabetes mellitus involves the destruction of the insulin-secreting cells of the pancreas and a subsequent lack of insulin.
• Immune-mediated polyarthritis: This is an autoimmune disorder that leads to inflammation in multiple joints, much like rheumatoid arthritis in humans.
• Inflammatory bowel disease: This is a syndrome caused by chronic irritation of the intestinal tract. Dogs with inflammatory bowel disease have chronic vomiting and diarrhea.

With the differences in these autoimmune diseases and the potential for complications or worsening of symptoms, you must work with your vet to develop the best protocol of medication, supportive therapy, and diet. No diet can cure an autoimmune disease, but it can provide additional support.

If you are concerned about the health and well-being of your pet, seek veterinary advice for the best course of action.
