Understanding Gluten and Dogs’ Gluten Sensitivity

Gluten is a protein naturally found in various grains, including wheat, barley, and rye. While most dogs can digest gluten without issues, some develop what’s known as gluten sensitivity or gluten intolerance. This condition affects approximately 10% of dogs with food allergies, making it important for pet owners to recognize its signs and symptoms.

Common sources of gluten in dog food include:

Commercial dry kibble
Many popular dog treats
Table scraps containing bread or pasta
Some medications and supplements
Certain processed dog chews

Gluten Intolerance vs. Celiac Disease

It’s important to note that gluten intolerance in dogs differs from celiac disease. While celiac disease is an autoimmune condition that attacks the small intestine, gluten sensitivity is an adverse reaction to gluten that doesn’t involve an autoimmune response. This distinction is crucial for proper diagnosis and treatment. Some breeds, like Irish Setters, show a higher predisposition to gluten-related issues.

Gurgling stomach sounds
Frequent bowel movements

Skin and Coat Problems

Gluten-sensitive dogs frequently experience:
