āThis is Georgeāand although his genes are part of his story, they donāt have to write every chapter.ā
Your dogās genetics may create a tendencyābut they donāt always decide the outcome.
A dog may inherit a tendency towards obesity, inflammation, allergies or certain health conditions. But having a genetic susceptibility does not mean illness is inevitable.
Think of your dogās genes like a collection of switches and dimmers. The DNA itself doesnāt change, but some genes can become more or less active in response to the messages the body receives.
Those messages come from many places:
šæ Food and nutrients
šæ Gut health
šæ Stress and sleep
šæ Exercise
šæ Medications
šæ Environmental chemicals and toxins
šæ Age and lifestyle
This is known as epigeneticsāthe way environment and lifestyle can influence how genes behave without changing the actual DNA.
And this is where nutrition becomes so much more than simply filling the bowl.
Food provides the body with the materials and biological signals it uses to support immune function, regulate inflammation, produce hormones, maintain the gut microbiome, repair cells and manage everyday toxin exposure.
Omega-3 fatty acids can influence inflammatory pathways.
Certain fibres feed beneficial gut bacteria, which produce compounds that communicate with the immune system and the rest of the body.
Fresh whole foods provide vitamins, minerals, antioxidants and natural plant compounds that the body uses in countless processes.
This doesnāt mean one food can magically āswitch offā an allergy gene or prevent every disease. Biology is far more complex than that.
But it does mean that genetics are only one part of your dogās story.
The food they eat every day, the health of their gut, their environment, stress levels, medications and total toxin load all help shape how that story unfolds.
This is why I look beyond simply asking:
āDoes this food meet the minimum nutritional requirements?ā
I also want to know:
What is this food repeatedly asking the body to process, regulate and respond toāmeal after meal, year after year?
Your dogās bowl contains more than calories. It contains information.
Have you noticed a difference in your dog after changing their food, routine or environment?
