How it works
The gut is the control center of your dog's health. This is where nutrients are absorbed, where most of the immune system lives, and where it's decided how good your dog feels.
The problem: The gut flora is a delicate ecosystem. Even small disruptions, a new food, stress at the vet, something they shouldn't have eaten, can tip the balance.
You notice it in loose stools, gas, restlessness, or a dog that just isn't quite on top form. That's exactly where our Holy Gut topper comes in: daily support for a stable gut flora, smooth digestion, and a strong immune system.
How it works: The Holy Gut topper combines selected plant-based raw ingredients whose nutritional effects on digestion complement each other. Natural fiber from Jerusalem artichoke, artichoke, carrots, carob, and flaxseed promotes a balanced gut flora, supports normal digestive function, and contributes to regular, well-formed stools. Bitter compounds from artichoke and valuable phytonutrients from milk thistle fruit round out the recipe and support digestive metabolism.

In 2019, we flew to Romania together and saw something we couldn't forget. Thousands of street dogs. Hunger. No home. We couldn't just fly back and act as if nothing had happened.
