The only thing we’d change about our dogs is that we’d get to keep them with us longer. So, we’re always looking for how to keep them the healthiest we can. The connection between gut health and a dog’s lifespan is definitely there–and backed by science that we can use to help our dogs be their happiest and healthiest. Gut health affects a dog’s lifespan, so upping our dog’s gut health game is the key!

That’s always the question, isn’t it? It is often thought that one dog year equals seven human years, but the conversion from dog years to human years is more nuanced, with the first two years of a dog’s life equating to more than seven human years each. Afterward, each dog year equals approximately four to five human years, with variations based on size and breed.

Larger breeds typically have a shorter lifespan, often due to the rapid aging process and susceptibility to certain diseases. Giant breeds often have the shortest lifespans among dogs. Their large size can contribute to various health issues, making gut health management through diet and supplements crucial. On average, large breeds tend to live about 8 to 12 years and giant breeds tend to live about 6-10 years.

A landmark study by Purina spanning 14 years demonstrated that dogs maintained in a lean body condition from puppyhood lived longer and healthier lives. The study found that on average, lean-fed dogs lived 1.8 years longer, which translates to about a 15% longer lifespan. These dogs also showed delayed onset of chronic diseases, greater insulin sensitivity, and better immune defense over time​​​​​​.

The gut microbiome is made of bacteria, fungi, and other microbes, and is foundational to your dog’s health. It contributes to digestion, vitamin production, serotonin generation, gut lining protection, and immune system support. Basically, it rules your dog’s health. An imbalanced microbiome can lead to various health issues like itchy skin, vomiting, diarrhea, constipation, and bad breath​​, just to name a few.

So what factors affect your dog’s gut microbiome and, incidentally, their life expectancy? Disease, age, diet, and medications can cause long-term disruptions to the gut microbiome. Feeding a healthy diet is crucial to maintaining a balanced gut microbiome, which in turn supports the immune system and may help prevent common illnesses​​.

The gut microbiota undergoes significant changes throughout a dog’s life. These changes influence age-related processes and impact the gut microbiota and its related metabolic changes. Aging in dogs, like in humans, is determined by a lot of complex interactions with environmental factors and internal genetics, as well as with the gut microbiome, which plays a central role. Studies have shown variations in the microbiome composition and functional features related to aging, indicating a connection between gut health and longevity​​.

When your dog’s microbiome is plagued with cellular oxidative stress, it can react pretty quickly. This leads to inflammation, infections, obesity, and potential cancers. But what exactly IS cellular oxidative stress in dogs? It’s a physiological condition where there is an imbalance between the production of reactive oxygen species (ROS) and the body’s ability to detox these reactive products to repair the damage it caused. Whew, right? It’s a complicated process in your dog’s gut, actually. Reactive oxygen species, like free radicals, are normal byproducts of cellular metabolism but they can cause damage to cells, proteins, and DNA when their levels become too high.

When this happens, it contributes to aging and various diseases in dogs, similar to humans. It’s linked to inflammation, and degenerative diseases, and can make other health conditions worse. Your dog’s body has natural antioxidant mechanisms to counteract this oxidative stress, but this can be compromised if their gut health isn’t in the best shape.

In dogs, oxidative stress can be influenced by various factors, including environmental pollutants, dietary deficiencies, or a lack of exercise. Managing oxidative stress often involves addressing these contributing factors, possibly through improved diet, exercise, and in some cases, antioxidant supplements. Balancing the gut microbiome with certain nutrients and supplements can counteract this stress, though! Foods or supplements that activate the body’s Nrf-2 pathway, such as turmeric and green tea, are great to help maintain a healthy gut microbiome​​.

Extending a dog’s lifespan through nutritional and gut health improvement involves a few different things, but the first and most important is focusing on the diet and supplements they have. Their overall lifestyle is important, but research continues to suggest that gut health is crucial for longevity, as it influences immune function, nutrient absorption, and overall well-being. We already know that the oral microbiome is super important to their gut and overall health, and that’s why we wanted to incorporate ingredients that mattered in our Charming Chompers Chews. Not only are they a ‘treat’ your dog will love and will help keep their breath fresh and teeth cleaner, but they also contribute to your dog’s better gut health, too! The ingredients we chose to include may not be your typical dental chew ingredients, but we’re focusing on overall health and vitality with Charming Chompers ingredients!

• Miscanthus Grass: This eco-friendly and sustainable grass is a good source of fiber, which aids in digestive health by promoting regular bowel movements and supporting a healthy gut microbiome.
• Sweet Potato: Rich in vitamins, minerals, and antioxidants, sweet potatoes are beneficial for gut health. They provide dietary fiber, which helps to maintain a healthy digestive system.
• Pumpkin: Pumpkin is another excellent source of fiber. It can help regulate a dog’s digestive system, alleviate diarrhea and constipation, and contribute to overall gut health.
• Inulin: This prebiotic fiber found in many plants feeds the beneficial bacteria in the gut. It helps improve bowel function and enhances the absorption of nutrients.
• Yogurt: A good source of probiotics, yogurt helps balance the gut microbiome, supporting healthy digestion and immune function.
• Lactobacillus Product: This probiotic supplement can aid in maintaining a healthy balance of gut bacteria, essential for optimal nutrient absorption and immune system support.
• Alfalfa Leaf Concentrate: Rich in vitamins and minerals, alfalfa can support digestive health and provide anti-inflammatory benefits.
• Parsley: Known for its anti-inflammatory properties, parsley can also help freshen a dog’s breath and support kidney health.
• Natural Mint Flavor: While primarily used for breath freshening, mint can also have mild soothing effects on the stomach and intestines.
• Green Tea Extract: Contains antioxidants that may reduce inflammation and promote healthy aging.
• Blueberries: High in antioxidants and fiber, blueberries support gut health and can help reduce oxidative stress.
• Rosemary: This herb has anti-inflammatory and antioxidant properties, which can support digestive health and overall well-being.
• Coconut Oil: Contains medium-chain triglycerides (MCTs) that can aid in digestion, improve coat health, and potentially boost cognitive function in older dogs.
