After breeding dogs holistically for over 20 years, I’ve learned something that changes everything once you learn it: most of what we call “dog viruses” have nothing to do with germs invading from the outside.

Let me explain this in simple terms. The idea we’ve all been taught—germ theory—says a specific virus or bacteria comes along and makes your dog sick. But here’s what I have been learning over the past year: virology has never actually proven the existence of any viruses in the isolated, purified way that real science requires. Rather than the body being attacked, symptoms are what the body creates on purpose to heal itself and return to balance.

A runny nose, ear infection, or bout of lethargy isn’t the enemy—it’s your dog’s intelligent system working to flush out toxins or correct a deficiency. The real drivers of illness aren’t germs. They’re toxicity (from ultra-processed food, chemicals, vaccines, or everyday environmental overload) and deficiency (lack of species-appropriate nutrition, fresh air, sunlight, and natural movement). When the terrain—the internal environment of the gut, cells, etc..—gets out of balance, the body starts exhibiting symptoms. That’s the “virus” you’re seeing.

In our breeding program, we’ve kept our dogs remarkably healthy by focusing on the terrain instead of chasing symptoms. Our pack lives outside year-round, breathing fresh air, moving freely on natural ground, and eating raw, species-appropriate food. No constant ear infections. No unexplained lethargy. No endless vet visits. That lifestyle alone has protected generations of our dogs from the usual laundry list of “mysterious” issues.

Stay tuned for Part 2 tomorrow where I discuss one of the biggest terrain destroyers for dogs.
