Breed-Specific Diseases and Proactive Care: A Dietary Strategy to Extend Your Dog's Health Span

To Lengthen Our Happy Time with Our Dogs: The Concept of Health Span

Life with our dogs brings us, their owners, irreplaceable joy and comfort. Their innocent smiles, the love they express with their entire bodies, and the warmth of their presence in our daily lives. It is a universal wish for all owners that our beloved family members walk alongside us for as long as possible, in good health.

In recent years, advancements in medical technology and improvements in living environments have dramatically extended the average lifespan of dogs. According to the 2023 National Dog and Cat Ownership Survey by the Japan Pet Food Association, the average lifespan of a dog in Japan has reached 14.76 years. However, it's not just about living longer; a crucial perspective for modern dog owners is how to maintain the quality of that life—in other words, their "health span."

Health span is the period one can live vigorously without needing medical treatment or nursing care. It means supporting our dogs so that even when they begin to feel the effects of old age, they can spend their days joyfully and comfortably, free from pain and suffering. This is the theme we must now seriously address. This article will focus specifically on "proactive care" and "diet" to extend our dogs' health span, providing a detailed explanation of breed-specific disease risks and their preventive measures.

Different Disease Risks by Breed and the Concept of a "Pre-Symptomatic" Condition

Just like humans, dogs have individual differences, and certain breeds have a predisposition to specific diseases. This is a result of years of breeding that have emphasized particular genetic traits. While these traits are part of the breed's unique charm, they are also points of caution for owners. The key to maximizing our dogs' health span is not to act after a disease has developed, but to intervene at the stage before illness—the "pre-symptomatic" stage.

What Is a "Pre-Symptomatic" Condition? Don't Miss the Signs Before Illness Strikes

The term "pre-symptomatic" refers to a state that, while not yet diagnosed as a disease, is beginning to deviate from a healthy condition. This concept, long used in human medicine, is now gaining recognition for its importance in veterinary care. For example, slight abnormalities in blood test results, a general lack of energy, a decrease in appetite, or an unusual way of walking—these subtle changes you notice in daily life could be signs of a pre-symptomatic condition.

These signs may not be enough for a veterinarian to make a formal diagnosis, but if left unaddressed, they carry the risk of progressing into a full-blown illness. By providing appropriate care at the pre-symptomatic stage, it becomes possible to slow the progression of a disease or even prevent its onset entirely. A dietary approach, in particular, is a highly effective means of supporting long-term health without placing a burden on your dog's body.

Common Disease Tendencies by Breed and the Importance of Early Care

Below are the disease tendencies for several popular dog breeds and the importance of dietary prevention at the pre-symptomatic stage. Understanding the specific characteristics of your dog's breed and being mindful of proactive care from an early age is the first step in supporting their health span.

• Toy Poodle: Patellar luxation, tracheal collapse, skin disorders, Legg-Calvé-Perthes disease, etc. Patellar luxation, especially common in small dogs, is seen in approximately 20% of small breeds according to some statistics. Maintaining joint health and a proper body weight is crucial.
• Shiba Inu: Allergic dermatitis, atopy, glaucoma, hypothyroidism, etc. These are often caused by a weakened skin barrier function or an overactive immune system, requiring care for the gut environment and measures against allergens.
• Golden Retriever: Hip dysplasia, elbow dysplasia, cancer, heart disease, etc. Joint diseases specific to large breeds are related not only to genetic factors but also to excessive nutrition and exercise during their growth phase. Cancer is a major disease, accounting for about 30% of deaths in dogs, and Golden Retrievers are at a higher risk for specific types of cancer (e.g., hemangiosarcoma). A diet high in antioxidants is expected to help with prevention.
• Chihuahua: Mitral valve insufficiency (heart disease), hydrocephalus, hypoglycemia, patellar luxation, etc. As a small breed, they are at high risk for developing heart disease, making weight management and a heart-friendly diet important.
• Miniature Dachshund: Intervertebral disc disease, skin disorders, epilepsy, etc. Due to their long bodies, they have a high risk of intervertebral disc disease. Weight management from a young age and proper nutritional support for the spine are essential.

Major Diseases by Breed and Their Dietary Prevention Approaches

As a conscientious owner, knowing your breed's specific disease risks is extremely important. And the most accessible and powerful tool to address these diseases at the "pre-symptomatic" stage is their "diet." Here, we'll introduce specific and effective dietary approaches for the major diseases common to each breed.

Joint and Skin Care for Small Breeds: Toy Poodles, Chihuahuas, and Miniature Dachshunds

• Dietary Approach for Joint Diseases (Patellar Luxation, Intervertebral Disc Disease, etc.)

  For patellar luxation common in Toy Poodles and Chihuahuas, and intervertebral disc disease in Miniature Dachshunds, maintaining a proper body weight is paramount. Excess weight increases the burden on the joints and can worsen symptoms.

  • Weight Management: Base their diet on low-calorie, nutritionally balanced food and avoid excessive treats.
  • Joint Support Ingredients: Supplement their diet with ingredients like glucosamine, chondroitin, green-lipped mussel, and MSM (Methylsulfonylmethane), which are components of joints or are expected to help reduce inflammation. These are believed to aid in cartilage regeneration and protection.
  • Anti-inflammatory Action: Omega-3 fatty acids (especially EPA and DHA) are expected to have an anti-inflammatory effect. Salmon oil and flaxseed oil are good sources.

• Dietary Approach for Skin Conditions (Allergies, Dryness, etc.)

  Small dogs tend to have delicate skin and are often troubled by skin issues caused by food or environmental allergies.

  • Allergen Management: Consider single-protein dog foods that avoid common allergens (like beef, chicken, dairy, grains) or foods containing hydrolyzed proteins.
  • Improving Gut Health: The gut is closely linked to immune function, and a healthy gut environment can lead to improvements in skin problems. Incorporating ingredients rich in probiotics and prebiotics (dietary fiber) is recommended.
  • Skin Barrier Support: A proper balance of Omega-3/6 fatty acids can strengthen the skin's barrier function and is expected to reduce dryness and itching. Zinc and vitamins A and E are also essential nutrients for skin health.

Joint, Cancer, and Heart Care for Medium and Large Breeds: Shiba Inus and Golden Retrievers

• Dietary Approach for Joint Diseases (Hip Dysplasia, Elbow Dysplasia, etc.)

  Large breeds like Golden Retrievers are at high risk for serious joint diseases such as hip and elbow dysplasia. While these conditions have a strong genetic component, nutritional management during their growth phase significantly impacts their onset and progression.

  • Nutritional Management During Growth: Rapid growth places excessive strain on joints, so a proper balance of calories, calcium, and phosphorus is crucial during this period. Excessive nutritional intake should be avoided.
  • Weight Management: Similar to small dogs, maintaining a proper body weight throughout their life minimizes the strain on their joints.
  • Anti-inflammatory and Cartilage-Protecting Ingredients: Actively incorporating glucosamine, chondroitin, MSM, and Omega-3 fatty acids can help suppress joint inflammation and support cartilage health.

• Dietary Approach for Cancer Prevention

  Golden Retrievers are one of the breeds with a particularly high risk of developing cancer. Dietary cancer prevention focuses on boosting the immune system and reducing cellular oxidative stress.

  • Antioxidant Ingredients: Actively incorporate ingredients rich in powerful antioxidants that prevent cellular oxidation, such as vitamins C and E, beta-carotene, selenium, and polyphenols (found in blueberries, green tea extract, etc.).
  • Boosting Immunity: Probiotics, prebiotics, and the amino acids and collagen found in bone broth help to regulate the gut environment and support the activation of immune cells.
  • High-Quality Protein: High-quality protein is essential for the production of immune cells. It's important to provide a balanced diet of human-grade meat and fish.

• Dietary Approach for Heart Disease (Mitral Valve Insufficiency, etc.)

  While heart disease is also common in small dogs like Chihuahuas, large breeds are also at risk. Caution is especially needed as they enter their senior years.

  • Sodium Restriction: Properly manage the intake of sodium, which can put a strain on the heart. When choosing commercial dog food, select low-sodium options or adjust levels in homemade meals.
  • Taurine & L-Carnitine: These amino acids are crucial nutrients that support the function of the heart muscle. Taurine, in particular, is known to be effective in preventing cardiomyopathy in dogs.
  • Omega-3 Fatty Acids: These are expected to reduce inflammation and improve blood flow, contributing to the maintenance of heart health.

These dietary approaches are part of "proactive care." If a disease has already developed, it is essential to follow the guidance of a veterinarian for appropriate treatment and dietary therapy.

The Latest Diets and Testing Methods to Accelerate Proactive Care

To extend your dog's health span, it's essential to adopt a "preventive medicine" perspective—catching early signs of illness and actively working to prevent them, rather than just relying on conventional treatment. Recently, groundbreaking testing methods and more personalized dietary options have emerged to accelerate this preventive approach.

A New Option in Canine Preventive Medicine: The Potential of miRNA Testing

In the field of "preventive medicine for dogs," miRNA (microRNA) testing is gaining attention. miRNA is expected to serve as a biomarker indicating cellular abnormalities and signs of disease in the body. It may allow for the early detection of risks for various diseases from a very small sample of blood or urine.

• What is miRNA Testing?

  miRNA are small RNA molecules that regulate gene expression. It's known that their patterns change when specific diseases or cellular abnormalities occur. By capturing these changes, it becomes possible to assess disease risk at a stage before symptoms appear, or at an early stage that is difficult to detect with conventional tests. For example, research is advancing on its use in the early detection of cancer, as well as signs of heart disease, kidney disease, and cognitive decline. Some testing institutions have already started using it for early cancer screening, with some research suggesting it can detect certain cancers at an early stage with a sensitivity of over 80%.

• How to Use the Test Results

  If an miRNA test indicates a high risk for a disease, you can start specific preventive measures, lifestyle improvements, and dietary reviews early on. This increases the likelihood of delaying the onset of the disease or preventing it from becoming severe. For example, if a specific cancer risk is identified, you can increase the intake of foods high in antioxidants or consult with your veterinarian to increase the frequency of regular, more detailed check-ups.

Boosting Immunity Through Gut Health: Utilizing "Bone Broth for Dogs"

"Bone broth," which has recently gained popularity as a health food for humans, is also a very effective ingredient for proactive care in dogs. Bone broth is a soup rich in collagen, minerals, and amino acids, extracted by simmering bones and joints for an extended period. For dogs, low-sodium or salt-free versions specifically made for them are recommended.

• The Health Benefits of Bone Broth

  • Improved Gut Environment: The abundant gelatin protects the intestinal wall and supports gut health. Since about 70% of immune cells are said to reside in the gut, improving the gut environment directly leads to enhanced immunity.
  • Joint Health: It is rich in joint components like collagen, glucosamine, and chondroitin, which help with joint flexibility and pain relief.
  • Detoxification: Amino acids like glycine assist the liver's detoxification function, supporting the elimination of waste products from the body.
  • Hydration: It is also suitable for hydration and nutritional support during periods of poor appetite or recovery from illness.

• Use with Homemade or Commercial Dog Food

  By pouring it over commercial dog food or using it as a base for homemade meals, you can enhance the nutritional value and palatability of their regular diet. Choose additive-free, salt-free "bone broth for dogs" products, or if making it at home, simmer chicken carcasses or beef bones slowly. Be extremely careful not to include ingredients that are harmful to dogs, such as onions or leeks.

The Optimal Choice for Your Dog: "Custom-Made Dog Food"

Not only do disease risks differ by breed, but even within the same breed, activity levels, allergy history, pre-existing conditions, and digestive capabilities vary widely from dog to dog. Commercial dog foods are made based on general nutritional standards for dogs, making it difficult to perfectly meet every individual's needs.

• The Importance of a Personalized Diet

  "Custom-made dog food" refers to a diet where veterinarians or nutritionists design the optimal nutritional balance and ingredients based on your dog's individual information (breed, age, weight, activity level, allergies, current health status, future risks, etc.). This allows for the provision of the best "proactive care diet" for your dog, helping to reduce specific disease risks, alleviate allergy symptoms, and support the digestive system.

• Custom Diet Design as Seen with HARENOHI

  For example, a "diet design brand" like HARENOHI emphasizes "proactive care diets" and provides "custom-made meals" tailored to each dog's condition. This involves not just combining nutrients, but also considering the quality of ingredients, cooking methods, and ease of digestion to create a scientifically-backed diet plan. By using carefully selected "human-grade ingredients" with a focus on being domestically produced in Japan, they provide a diet that is truly gentle on a dog's body, addressing their potential health risks from an early stage and supporting the extension of their health span.

What You Can Do for Your Dog: Diet Design and Daily Care

Extending your dog's health span isn't just about giving them expensive food. It requires improving the quality of their daily meals and providing continuous care. Here are some specific points on diet design and care that owners can implement.

Why Choose "Human-Grade, Domestically-Produced Dog Food"

Because it's something your beloved dog eats, you want to be particular about its quality. The options for "human-grade, domestically-produced dog food" have been increasing, and they offer clear advantages.

• Safety and Reliability

  "Human-grade" means that the ingredients used are of a quality fit for human consumption. This significantly reduces the risk of inferior raw materials or low-quality by-products being used. Furthermore, "domestically-produced dog food" (in Japan) is manufactured under Japan's strict quality standards and regulations, ensuring high transparency and peace of mind from raw material procurement to the manufacturing process. Compared to imported products, the shorter transportation distance also tends to help maintain freshness.

• Commitment to Being Additive-Free

  Many human-grade, domestically-produced dog foods go to great lengths to eliminate unnecessary additives like artificial preservatives, colorings, and flavorings. These additives can cause allergies and have been linked to long-term health risks. Choosing food that utilizes the natural taste and nutrition of its ingredients reduces the burden on your dog's body and helps bring out their innate health.

Adjusting Senior Dog Diets and Continuing Proactive Care

As dogs enter their senior years, their bodies undergo various changes, such as a decline in digestive function, a slower metabolism, reduced activity levels, and a weakening of joints and internal organs. Adjusting their diet to match this stage of life is particularly important for maintaining their health span.

• Easily Digestible, Nutrient-Dense Food

  Since senior dogs have weaker digestive systems, it's recommended to choose easily digestible ingredients and feed them in smaller, more frequent meals. Protein is important for maintaining muscle mass, but to be mindful of kidney health, provide a moderate amount of high-quality, easily digestible protein.

• Support for Joints, Brain, and Immunity

  For joint health, the continued intake of glucosamine, chondroitin, and Omega-3 fatty acids is essential. Additionally, antioxidants and DHA/EPA help maintain brain health and are expected to slow cognitive decline. To prevent a weakened immune system, ensure they receive a balanced intake of vitamins and minerals.

• Promoting Water Intake

  Senior dogs may feel less thirsty or drink less water. Dehydration puts a strain on the kidneys, so it's important to consciously encourage water intake by adding moisture to their food or mixing in bone broth.
