GUT FEELINGS, CLEAR MINDS: WHY GLUTEN-FREE IS SMARTER NUTRITION FOR DOGS

At Celtic Connection, we’ve always believed that true wellness starts on the inside—and not just in the gut, but in the brain as well. That’s why every one of our recipes is 100% gluten-free. Why does that matter? Because research is beginning to reveal how gluten—once thought of as “just a grain issue”—can affect both the intestines and the brain.

The Brain: When Gluten Sparks Inflammation

A study from the University of Otago found that feeding gluten to mice caused inflammation in the hypothalamus, a region of the brain that helps regulate mood, appetite, and energy balance. While more research is needed in dogs, the takeaway is clear: what your pet eats may impact how they feel and behave.

Some owners notice shifts like hyperactivity, irritability, or brain fog—and removing gluten can help rebalance behaviour from the inside out.

The Gut: Damaged Villi, Poor Absorption

In dogs, gluten can trigger an immune reaction that damages the villi—tiny finger-like structures that absorb nutrients in the small intestine. The result? Poor nutrient uptake, chronic digestive issues, and lower vitality overall.

We like to say: A flat intestine can’t fuel a full life.

The Gut-Brain Axis: One System, One Solution

Science confirms what many pet parents have sensed for years: the gut and brain are deeply connected. Poor gut health can lead to poor mental health—and vice versa.

That’s why Celtic Connection is different. Our recipes are designed to:

- Reduce inflammation with gentle, gluten-free ingredients

- Promote gut healing and nutrient absorption

- Support calmer, more balanced behaviour

- Fuel your dog’s body and mind

Because a happy belly often leads to a happy brain—and every dog deserves both.
