Understanding Common Dog Health Issues and When to See a Veterinarian

Dogs can experience a wide range of health problems throughout their lives, from minor issues like dry skin to more serious conditions requiring veterinary care. Learning to recognize signs that your dog needs professional medical attention is one of the most important skills a pet owner can develop. This guide covers information about common health issues so you can understand what might be happening with your dog's body.

According to the American Veterinary Medical Association, some of the most frequently diagnosed conditions in dogs include ear infections, skin allergies, dental disease, and arthritis. Ear infections alone account for approximately 10 percent of veterinary visits. These conditions often show visible signs that owners can learn to recognize, such as excessive scratching, head shaking, or reluctance to eat hard food.

Knowing the difference between minor issues and emergencies matters greatly. For example, vomiting once might result from eating something inappropriate, but vomiting that continues for more than a few hours warrants veterinary attention. Similarly, a slight limp might resolve on its own, but limping that worsens or persists for several days suggests an underlying problem.

Other common conditions that bring dogs to veterinarians include:

• Obesity, which affects nearly 56 percent of dogs in the United States according to veterinary health surveys
• Urinary tract infections, which cause frequent urination and accidents in the house
• Gastrointestinal problems like diarrhea and constipation
• Eye problems ranging from minor discharge to more serious conditions
• Respiratory issues causing coughing or difficulty breathing
• Behavioral changes that might indicate pain or illness

Understanding these common issues helps you communicate better with your veterinarian. Keep notes about when symptoms started, how often they occur, and what your dog was doing when you first noticed the problem. This information helps veterinarians narrow down possible causes and provide better care.

Practical takeaway: Create a simple health journal for your dog where you record any symptoms or changes in behavior. Write down when the symptoms started and what they look like. This creates a record you can share with your veterinarian during visits.

Preventive Care Strategies and Routine Health Maintenance

Preventive care represents one of the most effective ways to keep dogs healthy throughout their lives. Rather than waiting for problems to develop, preventive care involves regular actions that reduce the risk of illness and catch problems early when they're often easier to manage. Many health issues in dogs can be prevented or their severity reduced through consistent preventive measures.

Vaccinations form a cornerstone of preventive care for dogs. Core vaccines protect against diseases like rabies, distemper, and parvovirus. The rabies vaccine is required by law in all 50 states, and most veterinarians recommend core vaccines for all dogs. Puppies typically receive a series of vaccines starting at six weeks of age, while adult dogs need booster shots. Your veterinarian can explain which vaccines your individual dog needs based on age, lifestyle, and risk factors.

Regular dental care significantly impacts a dog's overall health. Dental disease affects a large percentage of adult dogs, and the bacteria from infected teeth can spread to the heart, liver, and kidneys. Daily tooth brushing, when possible, helps prevent plaque and tartar buildup. Many veterinarians recommend professional cleaning at least once per year, though individual dogs may need more frequent cleanings.

Parasite prevention protects dogs from fleas, ticks, heartworms, and intestinal worms. These parasites cause serious health problems ranging from anemia to heart disease. Modern parasite prevention products come in several forms:

• Topical treatments applied monthly to the skin
• Oral medications given as tablets or chewables
• Injectable treatments that last several months
• Collars that provide protection over several months

Your veterinarian can recommend products appropriate for your dog's age, weight, and health status. Year-round parasite prevention is important in most regions, as parasites remain active even during cooler months in many areas.

Weight management represents another crucial preventive measure. Overweight dogs face higher risks for diabetes, heart disease, arthritis, and certain cancers. Maintaining healthy body weight through appropriate nutrition and exercise helps dogs live longer, more comfortable lives. Your veterinarian can help determine if your dog is at a healthy weight and suggest adjustments if needed.

Practical takeaway: Schedule annual wellness visits with your veterinarian even when your dog appears perfectly healthy. These visits establish a baseline for your dog's health and allow veterinarians to catch early signs of problems before they become serious.

Nutrition, Diet, and Feeding Guidelines for Different Life Stages

What you feed your dog significantly impacts their health, energy level, and longevity. Dogs require specific nutrients to thrive, and nutritional needs change as they age. Understanding how to feed dogs properly at different life stages helps prevent nutritional deficiencies and diet-related health problems.

Puppies have different nutritional requirements than adult dogs because they're growing rapidly. They need higher levels of protein and calories to support development. Large-breed puppies especially require carefully balanced calcium and phosphorus levels to support proper bone development and prevent orthopedic problems later. Most veterinarians recommend feeding puppies a food specifically formulated for puppies rather than adult dog food.

Adult dogs, typically those between one and seven years old, require a balanced diet with appropriate levels of protein, fat, and other nutrients. The amount to feed depends on individual factors including age, activity level, metabolism, and body size. A study published in veterinary journals found that overfeeding is one of the most common nutritional mistakes dog owners make. Measuring food with a cup and following feeding guidelines on dog food bags helps prevent overfeeding.

Senior dogs, generally those over seven years old, may benefit from diet modifications. Some seniors have trouble chewing hard kibble, making softer foods or moistened kibble better options. Others benefit from reduced calories if they're less active, while some need additional joint-supporting nutrients like glucosamine. Senior dogs also may need adjusted levels of protein, fiber, and certain minerals.

Dog food options include:

• Commercial kibble, which is convenient and shelf-stable
• Canned or wet foods, often more palatable and easier to chew
• Fresh or frozen commercial diets
• Home-prepared diets, which require careful formulation to ensure complete nutrition
• Raw diets, which require careful handling to prevent bacterial contamination

When changing dog food, gradual transitions over 7-10 days help prevent digestive upset. Mixing increasing amounts of the new food with decreasing amounts of the old food allows your dog's digestive system to adjust.

Certain foods common in human diets are toxic to dogs and should never be fed. Chocolate, grapes, raisins, onions, garlic, xylitol-containing products, macadamia nuts, and avocado can cause serious poisoning. Even small amounts of these foods can cause health problems in some dogs.

Practical takeaway: Read dog food labels and look for foods that state they meet the nutritional standards established by the Association of American Feed Control Officials (AAFCO). Work with your veterinarian to choose foods appropriate for your dog's age, size, activity level, and any health conditions.

Exercise, Mental Stimulation, and Behavioral Health

Physical exercise and mental stimulation are as important to dogs' overall health as proper nutrition and medical care. Dogs that don't receive adequate exercise and mental engagement often develop behavioral problems and face higher risks for obesity and anxiety-related conditions. The amount and type of exercise your dog needs depends on breed, age, health status, and individual temperament.

Most healthy adult dogs benefit from at least 30 to 60 minutes of moderate exercise daily, though some high-energy breeds may need significantly more. This exercise can come from walks, running, fetch, swimming, or dog sports. Regular physical activity maintains healthy weight, strengthens muscles and bones, and helps dogs sleep better at night.

Mental stimulation is equally important as physical exercise. Dogs are intelligent animals
