Unlocking Epigenetics for Happier, Healthier Dogs

Ever wonder why two puppies from the same litter can have such different personalities or health outcomes? It’s not just about their genes. We often think of our pets’ health as being determined by their DNA, a sort of fixed blueprint. But what if I told you that you have more influence than you think? This is where epigenetics comes in.

Think of genes as the hardware, and epigenetics as the software that tells them when and how to run. It’s the study of how behaviors and environment can cause changes that affect the way your pet’s genes work. This means we, as pet guardians, have a powerful role in shaping our dogs’ health and happiness. Let’s dive into how diet, stress, and our environment can tweak those genetic switches, leading to big changes in our pets.

I’m on a personal journey with my dog, Meru, that has brought this concept of epigenetics vividly to life. Meru’s genetic testing revealed she carries both genes for Degenerative Myelopathy (DM), a devastating disease that gradually robs dogs of their mobility. Knowing that this disease, often described as ‘doggy ALS,’ could begin to manifest around her eighth birthday, and that she’s currently seven, has spurred me into action. It’s a race against time, but also an opportunity to see if I can influence her outcome.

Diet and Epigenetics: Food as a Genetic Messenger 

What your pet eats isn’t just fuel; it’s a message to their genes. Every meal can influence how their DNA expresses itself. For senior dogs, and especially for Meru, this is crucial. Veterinary medicine is constantly evolving, and recent research has shown that a fresh, non-processed diet can potentially delay or even prevent some diseases like DM.

• Omega-3 fatty acids: These are superstars for reducing inflammation, which is a common issue in aging pets. They also influence gene expression related to cognitive function and joint health, helping to keep those senior minds sharp and those joints moving smoothly. I’ve started adding high-quality fish oil to Meru’s meals, hoping to support her neurological health.
• Methyl donors (folate, choline): These nutrients are vital for DNA methylation, a key epigenetic process. Think of methylation as a way to fine-tune gene activity. Ensuring your senior dog gets enough of these can support overall cellular health.Foods Rich in Folate and Choline:
  • • Liver: Beef or chicken liveris a fantastic source of both folate and choline. However, it’s crucial to offer it in moderation due to its richness. A small amount mixed into their regular food is sufficient.
    • Eggs: Egg yolks are particularly high in choline. Cooked eggs are safe for dogs and can be a nutritious addition to their diet.
    • Leafy Greens (Spinach, Kale): While dogs are carnivores, small amounts of cooked leafy greens can provide folate. Ensure they are thoroughly washed and cooked to improve digestibility.
    • Certain Vegetables: Asparagus, and green beans, when cooked, can also provide some folate.
• Antioxidants: As dogs age, they experience more oxidative stress, which can lead to negative epigenetic changes. Antioxidants, like those found in colorful vegetables and fruits, protect against this damage.

  • Foods Rich in Antioxidants:

    • Blueberries: These berries are packed with antioxidants and are generally safe for dogs in small quantities.
    • Carrots: Carrots are a great source of beta-carotene, an antioxidant. They also provide fiber and are low in calories.
    • Sweet Potatoes: Cooked sweet potatoes offer antioxidants, vitamins, and fiber. Ensure they are cooked thoroughly and given without added seasonings.
    • Spinach: As stated above, spinach also provides antioxidants, along with other beneficial vitamins.

Here are some practical tips to optimize your senior dog’s diet, and what I’m doing for Meru:

• Choose high-quality, whole-food diets with minimal processed ingredients. I’ve switched Meru to a fresh, homemade diet, carefully selecting each ingredient.
• Add omega-3 supplements, especially for pets with joint issues or cognitive decline. Fish oil is now a daily addition to Meru’s food.
• Incorporate fresh, pet-safe vegetables and fruits for natural antioxidants. Blueberries, carrots, and spinach are now a regular part of Meru’s meals.
• Avoid excessive grain and processed carbohydrates, as these can contribute to inflammation and metabolic issues.

Stress and Epigenetics: The Silent Gene Modifier 

Just like us, pets experience stress, and chronic stress can leave lasting marks on their genes. Senior dogs, in particular, may be more sensitive to stress due to age-related changes.

• Hormonal Changes: Stress hormones like cortisol can alter gene expression related to anxiety, immune function, and behavior. This can lead to increased nervousness, weakened defenses, and even changes in how they interact with you and other pets.
• Environmental Stressors: Factors like noise, overcrowding, and lack of routine can contribute to chronic stress.

Here’s how you can create a calmer environment for your senior dog, and what I’m implementing for Meru:

• Create a calm, predictable environment with safe spaces and consistent routines. I’ve ensured Meru has her own quiet space and maintain a consistent daily exercise routine.
• Provide mental stimulation through puzzle toys and training. Keeping their minds active can reduce anxiety.
• Consider calming supplements or pheromone diffusers for anxious pets.
• Increase exercise, as this can reduce stress hormones. Gentle sniffari walks and playtime can work wonders.
• Practice positive reinforcement training. This builds confidence and reduces anxiety.

Environmental Toxins and Epigenetics: Minimizing Exposure 

Our pets are exposed to a variety of environmental toxins, from household cleaners to pesticides, and these can have epigenetic consequences. For senior dogs, whose detoxification systems may be less efficient, this is a serious concern.

• Heavy metals: These can disrupt gene expression related to neurological and immune function. Even trace amounts can accumulate over time, leading to health issues.
• Pesticides and herbicides: These are linked to an increased risk of certain cancers and developmental issues. Pay attention to the products you use in your yard and garden.
• Household chemicals: Air fresheners, cleaning supplies, and other chemicals can release volatile organic compounds (VOCs) that affect your pet’s health.

Here are some ways to minimize your pet’s exposure, and what I’m doing for Meru:

• Use natural, pet-safe cleaning products.
• Minimize the use of pesticides and herbicides in your yard.
• Ensure proper ventilation in your home.
• Filter your pet’s water to reduce exposure to heavy metals.
• Be mindful of air quality near roads, and industrial areas.

Empowering You to Make a Difference 

Epigenetics gives us a powerful tool to influence our pets’ health through diet, stress management, and minimizing toxin exposure. It’s about understanding that your actions today can shape your senior dog’s well-being for years to come.

You have the ability to make a real difference in your pet’s well-being by understanding and applying these principles. Small changes can lead to significant improvements in your furry friend’s health and happiness.

I may never know if my efforts with Meru will ultimately prevent the onset of DM. She may simply live a healthy life until her natural end. But if I can potentially spare her from this terrible disease, I will try everything in my power. Until then- she’s living her best life!

Wishing you and your senior companion many happy and healthy years together.
