The Gut–Brain Connection: Why Your Dog’s Tummy Affects Their Behavior

Did you know your dog’s gut and brain are in constant conversation? This is called the gut–brain axis, and it has a huge influence on your dog’s mood, stress levels, and even their behavior.

Your dog’s gut is home to trillions of tiny microbes that don’t just help digest food—they also create important chemicals that affect the brain. One of the most important is serotonin, sometimes called the “feel-good” hormone. Serotonin helps your dog feel calm, sleep soundly, and recover from stress. When the gut is out of balance, it can set off stress signals and inflammation that make it much harder for your dog to relax. For dogs with trauma or reactivity, this imbalance can make them even more anxious, sensitive, or quick to overreact.

Signs of an Unhappy Gut

Many pet parents assume their dog’s digestion is fine as long as stools look normal. But gut health can be more complicated than that. Sometimes the signs show up in surprising ways, including:

• Itchy skin or frequent ear infections – the gut and skin are closely linked.

• Low energy or fatigue – poor nutrient absorption can leave your dog drained.

• Bad breath or excessive gas – often a sign of bacterial imbalance.

• Unexplained weight gain or loss – the gut affects metabolism and how nutrients are used.

• Mood and behavior changes – a restless, anxious, or irritable dog may be struggling with gut-driven inflammation. READ MORE!

Hero Spotlight

Dixie, a Bernedoodle, is an important part of the Cheatham County School System. Last year, she spent her days at Kingston Springs Elementary, where her mom, Andrea, was principal. Today, Dixie is based at the main office alongside Andrea, who now serves as the district’s Behavior Coordinator. Together, they visit schools across Cheatham County, offering students comfort and support throughout their school day.

Dixie and Andrea are also the inspiration behind our program, “Dixie’s Classroom Companions,” which trains dogs and their handlers to serve as four-legged school counselors. Stay tuned—next week’s newsletter will introduce our newest “counselor” at Harpeth High School!
