For longer dog life, focus on high-quality, fresh, whole foods, emphasizing lean proteins (meat, fish, eggs), healthy fats (omega-3s from fish oil/sardines), antioxidant-rich fruits (blueberries, bananas, carrots), and fiber (sweet potatoes, pumpkins), supporting a healthy gut, strong immune system, and reduced inflammation, often found in raw or minimally processed diets, rather than relying solely on processed kibble.
Raw, Single Protein (Meat)
Studies indicate that a raw food diet can increase a dog's lifespan compared to feeding dry, preserved food. Dogs descend from wolves, who thrived on raw diets in the wild. While dogs are omnivores, protein and minerals from meat fulfil many of their nutritional needs.
Exercise and lifestyle choices are equally important factors in determining your dog's lifespan. Regular physical activity helps maintain a healthy weight, supports heart health, and reduces the risk of developing certain diseases.
Researchers followed 500 dogs over a five-year period and found a striking difference in lifespan: dogs fed a homemade, fresh food diet lived an average of 2.5 years longer than dogs fed commercial kibble.
Keep your dog at a slim, trim body weight. Obesity dramatically contributes to ever so many age-related, debilitating issues such as arthritis (a huge problem for way too many dogs), diabetes and heart disease. Feed your dog as little as it takes to maintain an ideal body condition score.
The 3-3-3 rule for dogs is a guideline for the adjustment period after adoption, outlining three phases: 3 Days (decompression, feeling overwhelmed/scared), 3 Weeks (starting to settle in, learning routine, personality emerges), and 3 Months (feeling secure, bonded, and truly at home). It helps new owners manage expectations and be patient as their rescue dog transitions, emphasizing calm energy, routine, and space in the early days to build trust.
Want your dog to live a longer life? Here are 6 science-backed tips
The leading cause of death in dogs, especially older dogs, is cancer (neoplasia), affecting about 1 in 4 dogs, similar to humans, with specific breeds at higher risk. Other significant causes include old age, heart disease, digestive disorders (like bloat), infectious diseases (like Parvo), and trauma, with sterilization influencing risks for cancer and infections.
The healthiest dog food depends on your dog's specific needs, but top veterinarian-recommended brands known for science-backed nutrition and meeting AAFCO standards include Hill's Science Diet, Royal Canin, and Purina Pro Plan, offering options for life stages and health conditions. For sensitive dogs or allergies, limited ingredient diets (LID) from brands like Prime100 (single protein, human-grade) or raw/air-dried diets from Eureka (high meat, organs) are excellent choices, focusing on whole, digestible ingredients for better gut and skin health, but always consult your vet first.
The 90/10 rule for dogs means 90% of their daily calories should come from a complete, balanced dog food, while only 10% should come from treats, training rewards, and any extra human foods or toppers, preventing nutritional imbalances and obesity. This guideline ensures essential vitamins and minerals are met through their main diet, keeping treats as occasional indulgences rather than dietary staples.
I've offered this advice to my veterinary clients for the past 30 years: “30 minutes a day helps keep the veterinarian away!” In addition to a nutritious diet, daily exercise is essential for your dog's health, longevity, and happiness. Most dogs require about 30 minutes of aerobic activity each day.
An hour for a dog feels much longer than an hour for a human because dogs perceive time more slowly due to their faster metabolism and heightened awareness of routines, so a 10-minute wait can feel like 70 minutes to them, and your hour-long absence feels like an eternity, though they don't grasp clock time but rather the intervals between events like meals, walks, and your return.
The aging profile of dogs varies according to their adult size (often determined by their breed): smaller breeds have an average lifespan of 10–15 years, with some even exceeding 18 years in age; medium breeds typically live for 10 to 13 years; and giant dog breeds have the lowest minimum lifespan, with an overall ...
Letting your dog gain too much weight
As Dr. Shari Brown, a veterinarian in Chesapeake, Virginia, notes, letting your dog get too heavy can not only reduce his life span but also his quality of life. “People do not realize that dogs do not process or break down food like we do,” she explains.
There's no single "number 1" healthiest dog food, as the best choice depends on your dog's age, breed, and health; however, look for foods meeting AAFCO standards (Association of American Feed Control Officials), with real meat as the first ingredient, and vet-recommended brands like Hill's Science Diet, Purina Pro Plan, and Royal Canin are often cited for balanced nutrition. Freshly prepared or raw diets can also be healthy but carry risks, so always consult your vet.
The 95% Rule in dog food labeling, set by AAFCO, means a product named after a specific ingredient (e.g., "Chicken Dog Food") must be at least 95% that ingredient by weight (excluding water) and 70% including water, with the ingredient listed first and comprising more than 95%. If two ingredients are named ("Chicken & Beef"), they must total 95% (minus water), with the first ingredient being more abundant and both making up at least 3% each. This rule ensures transparency, indicating foods with a very high concentration of the named ingredient.
The worst dog foods often contain cheap fillers like corn, wheat, and soy; unspecified "meat meals" or by-products; excessive sugar; and artificial colors/preservatives, with brands like Kibbles 'n Bits, Beneful, Gravy Train, and some Purina/Iams varieties frequently cited for low nutritional quality and questionable ingredients. Focus on avoiding poor-quality protein sources (unspecified meat meals), fillers, artificial additives, and dangerous human foods like chocolate, grapes, onions, and xylitol.
Oily fish like herring, salmon, sardines, and anchovies are tasty superfoods for dogs, packed with protein, healthy fats, and the essential fatty acid, Omega-3. Omega-3 fatty acids boost dogs' skin and coat health, as well as fight arthritis, inflammation, and brain aging.
Yes, dogs can eat cooked eggs in moderation. Boiled, scrambled, and poached are all great options—as long as they're plain and not cooked in butter or oil. Raw eggs should be avoided due to potential health risks such as salmonella and reduced nutrient absorption.
Heartworm disease is among the top silent killers of dogs and cats, and it's a slow and insidious disease which gradually incapacitates them. By the time pet owners notice the giveaway signs of this disease, serious damage may already have been caused.
Top 10 toxins for dogs are:
Following the loss of a companion, dogs do grieve for another dog, and their emotions may show in various ways. It is important to recognise that grief is a natural process for dogs, and they may exhibit signs such as heightened anxiety, changes in appetite, or withdrawal from activities they previously enjoyed.
The 3-3-3 rule for dogs is a guideline for the adjustment period after adoption, outlining three phases: 3 Days (decompression, feeling overwhelmed/scared), 3 Weeks (starting to settle in, learning routine, personality emerges), and 3 Months (feeling secure, bonded, and truly at home). It helps new owners manage expectations and be patient as their rescue dog transitions, emphasizing calm energy, routine, and space in the early days to build trust.
While more research is definitely needed, it is highly likely increased physical exercise is beneficial for cats and dogs in maintaining health and slowing aging. There's also plenty of evidence showing exercising with our dogs is good for our health. So, take your dog for a walk right now!
The "10 10 10 rule" for dogs refers to two main concepts: a potty training method for puppies (10 mins outside, 10 ft space, 10 mins supervision/reward) and the 80/10/10 guideline for raw feeding (80% muscle meat, 10% bone, 10% organ), both offering structure for training or diet. Another interpretation is the 10% rule for treats, limiting them to 10% of daily calories to maintain a balanced diet, ensuring most nutrition comes from complete dog food.
