Understanding Why Plants Don’t Get Cancer (Like Our Dogs Do)

As both a dog nutritionist and future acupuncturist, I’m often asked about cancer prevention for our dogs. One fascinating question that comes up when we discuss diet is: “Why don’t the plants we feed our dogs get cancer the way our pets do?” This opens up a beautiful window into understanding how we might better support our dogs’ health when we add plants to their meals.

As a student in Traditional Chinese Medicine (TCM), I often explore how cellular behavior affects Qi flow and overall systemic health in our dogs. The way plants handle abnormal cell growth offers fascinating insights into containment and cellular regulation – concepts that bridge both Eastern and Western perspectives.

Cancer – What Is It?

Cancer represents uncontrolled cellular proliferation. At its core, cancer is about uncontrolled cell growth—cells multiplying when and where they shouldn’t.

But here’s something fascinating: while both plants and our dogs can experience abnormal cell growth, they handle it very differently.

Think About Growth Gone Wild

When our dogs develop cancer, their cells can break free and travel through the body.

Cells begin to multiply abnormally, losing their natural growth inhibition

• Their flexible membranes allow them to change shape and squeeze between other cells
• They can break away from their original tissue (primary tumor site)
• These rogue cells enter the blood or lymphatic system
• They travel to new locations in the body At these new sites, they establish secondary growths (metastases)
• The process continues, creating systemic disease

But plants? They’ve evolved a brilliant containment system.

How Plants Handle Their Version of Cancer:

• Plants do get tumors and abnormal growths (yes, really!)
• Those gnarly burls you see on trees? That’s actually uncontrolled cell growth
• Crown galls in your garden? Also, abnormal growth caused by bacteria

The Key Difference? Containment. Plants have evolved a simple but effective strategy: their cells are surrounded by rigid walls made of cellulose. These walls act like built-in barriers. When a plant cell starts growing abnormally, it literally can’t go anywhere. It’s like having a built-in containment system.

In Our Dogs:

• Cells have flexible membranes
• Can easily move through tissues
• Can spread to other parts of the body
• Flexible cell membranes allow movement
• Essential for healing and immune function
• Unfortunately also permits cancer cell migration
• Lacks built-in physical containment mechanisms

In Plants:

• Cells have rigid walls
• Stay put where they are
• Abnormal growth remains localized
• The plant often just grows around the problem
• The cellulose barrier is structural, not biological
• Cannot transform into malignant spreading tumors
• Growth patterns follow plant architecture
• Containment is literally built into their cellular structure

So then what’s the whole point of this article?

To simply open the conversation about the inclusion of plants in your dog’s diet for it’s anti-cancer and chemoprotective benefits.

Beyond the Wolf Diet Debate

While some argue dogs should eat like wolves, research shows dogs have evolved to utilize plant nutrients effectively. They’ve developed additional genes for starch digestion and can benefit from carefully selected plant compounds.

Why This Matters for Your Dog’s Health

Understanding this difference helps us appreciate why a balanced diet that includes properly prepared plant foods can support our dogs’ health. Plants have developed various compounds over millions of years to manage their own growth challenges, and these same compounds can support our dogs’ cellular health when used appropriately.

Let’s break this down in a way that matters for your dog’s bowl.

As an advocate for fresh feeding, I do encourage a species-appropriate diet.

The Foundation (The majority of the bowl): Fresh muscle meat, organs, and raw meaty bones (for those that feed raw) form the core of the diet. This can be served raw or cooked based on your preference and your dog’s needs.

Strategic Plant Additions (10-30%): Focus on dark leafy greens, cruciferous vegetables, medicinal mushrooms (for those that feed mushrooms), and select berries. The key is proper selection, preparation and portion size.

• Selection of plants with strong containment properties
• Focus on foods that support cellular boundary integrity
• Integration of herbs that demonstrate growth regulation
• Consideration of food energetics that support proper cell signaling (this is where Traditional Chinese Medicine Food Therapy excels)

The Weight of Fear

I see it in the eyes of every client who comes to me with a cancer diagnosis – that paralyzing fear that seems to stop time itself. Whether it’s for their beloved dog or they’re sharing their own cancer journey, there’s a moment when the world seems to hold its breath.

I witness how fear of cancer can overshadow the very essence of living. Dog parents sometimes become so consumed by prevention that they forget to enjoy the simple joy of watching their dog chase a ball or splash in a puddle. Humans do this too – we can become so afraid of what might happen that we forget to fully inhabit what is happening.

A Different Way

Here’s what I’ve learned walking alongside countless families on various health journeys: The universe has an interesting way of responding to our energy. When we operate from a place of constant fear, we tend to attract more situations that fuel that fear. It’s as if the universal energy simply says “yes” to whatever we put out.

Think about it – when we’re afraid of cancer, we:

• See potential symptoms everywhere
• Feel anxious about every bump
• Miss the joy of the present moment
• Forget to celebrate life itself

Shifting the Energy

What if instead, we approached health – both for our dogs and ourselves – from a place of celebration? What if we viewed food not through the lens of fear (“Will this cause cancer?”) but through the lens of abundance (“Look at all these incredible tools nature has given us!”)?

Nature’s Wisdom

Every plant, every herb, every food that grows from this earth carries specific wisdom. When we approach our plates – and our dogs’ bowls – with this understanding, something shifts. We’re no longer just avoiding what might harm us; we’re actively choosing what will nourish us.

The earth provides:

• Foods that support cellular health
• Plants that protect against damage
• Herbs that strengthen resilience
• Nutrients that build vitality

Living with Awareness, Not Fear

Yes, the rainbow bridge awaits all of us and our beloved dogs. This is the natural order of things, and try as we might, we cannot control when that moment comes. But we can control how we live until then.

Being aware of cancer doesn’t mean we must live in its shadow. We can acknowledge it while still standing in the light of life, joy, and celebration.

I have shared the story of my nephew with those close to me. He was born with a heart that barely functioned. He did live till he was sixteen after multiple surgeries (eventually a new heart) and he inspired me to cherish every single day.

My own mother, had breast cancer during the time before pink ribbon campaigns. She had one breast removed and we lived our lives in gratitude for her health. She never labeled herself as “having cancer”. And with time we forgot she even had it. She lived another 35+ years after that diagnosis.

I’ve had countless dogs pass onto the other side. Some who’s fate wasn’t always what we anticipated but that’s just the sad and tragic turns of life. We don’t know how that ending story goes for any of us.

When Maggie, my senior dog had a lump on her shoulder, we left it alone for two years (it wasn’t growing fast or abnormally) but when she had a lump pop up on her elbow which grew fast and abnormally, we had it removed (along with the other lump) right away.

Walking Together

As I write this today, I find myself reflecting on my own journey – from helping dog parents with food choices to pursuing my doctorate in Acupuncture. Those who’ve been with me since the beginning have witnessed this evolution, watching as Traditional Chinese Medicine has deepened my understanding of health, healing, and the profound connection between all living things.

What began as a mission to guide dog parents through nutrition has blossomed into something far more meaningful. Through my studies of Qi – that vital force flowing through every living thing – I’ve come to understand that true health isn’t just about what we feed our dogs. It’s about the energy we bring to each moment, each meal, each interaction.

My education in Traditional Chinese Medicine has transformed how I see the world. Where I once saw only nutrients and ingredients, I now see the dance of energy – in our food, in our dogs, in ourselves. This deeper understanding has shown me that when we nourish our dogs, we’re not just feeding their bodies; we’re supporting their vital force, their essence, and their spirit.

In the articles to come, I’ll share specific insights about foods that offer cancer-protective benefits. But I invite you to receive this information not from a place of anxiety or fear, but from a space of empowerment and possibility. Because when we approach health from a place of celebration rather than fear, we align ourselves with life’s natural tendency toward wellness.

This is my promise to you: as I continue growing in my understanding, I’ll share not just the science of nutrition, but the wisdom of ancient healing traditions. Together, we’ll explore how to nurture our dogs’ vitality while celebrating the joy they bring to our lives.

Until we connect again, may you and your beloved dogs walk in harmony with life’s natural rhythms, finding moments of pure joy in your shared journey.

With gratitude for allowing me to be part of your path.
