Dog Health Care: Preventive Medicine and Wellness Checks
Keeping your dog healthy requires more than feeding good food and providing exercise. Preventive health care — the regular veterinary visits, vaccinations, parasite control, and daily observations that catch problems early — is the foundation of a long, happy life for your canine companion. The American Veterinary Medical Association recommends that healthy adult dogs receive a comprehensive veterinary examination at least once per year, and senior dogs should be seen every six months.
Preventive care is also cost-effective. Treating advanced dental disease, heartworm infection, or a preventable infectious disease costs significantly more than the preventive measures that would have avoided the problem entirely. Pet insurance can offset unexpected costs, but nothing replaces the value of regular wellness care.
The Annual Wellness Exam
A thorough wellness exam does more than update vaccinations. Your veterinarian will perform a head-to-tail assessment that evaluates every body system. They check your dog’s weight, body condition score, temperature, heart rate, and respiratory rate. They examine the eyes for cataracts, glaucoma, and retinal disease. They look in the ears for infection, inflammation, and parasites. They listen to the heart and lungs for murmurs, arrhythmias, and abnormal lung sounds.
The veterinarian palpates the abdomen to check organ size and detect masses. They feel the lymph nodes for enlargement that could indicate infection or cancer. They examine the skin and coat for parasites, lumps, and signs of allergic disease. They assess the teeth and gums for periodontal disease. They evaluate the joints for arthritis and range of motion. This comprehensive examination establishes a baseline and allows your veterinarian to detect problems early, when they are most treatable.
Diagnostic Testing
Annual wellness exams typically include basic diagnostic testing. Fecal examinations check for intestinal parasites like roundworms, hookworms, whipworms, and giardia. Heartworm testing is recommended annually even for dogs on year-round prevention. Blood work including a complete blood count and biochemistry panel provides valuable information about organ function, especially for middle-aged and senior dogs. Thyroid testing screens for hypothyroidism, a common endocrine disorder in dogs.
Your veterinarian may recommend additional testing based on your dog’s breed, age, and risk factors. Lyme disease, ehrlichiosis, and anaplasmosis testing is recommended in areas where tick-borne diseases are prevalent. Urinalysis screens for urinary tract infections, kidney disease, and diabetes. The cost of catching a problem early is almost always less than treating it after symptoms appear.
Vaccinations
Vaccines protect dogs from serious and potentially fatal infectious diseases. The AVMA categorizes vaccines as core — recommended for all dogs — and non-core — recommended based on lifestyle and geographic location.
Core Vaccines
The core vaccines for dogs are distemper, adenovirus (hepatitis), parvovirus, and rabies. Distemper is a highly contagious viral disease that affects the respiratory, gastrointestinal, and nervous systems. Parvovirus causes severe vomiting and hemorrhagic diarrhea and is often fatal, especially in puppies. Rabies is nearly always fatal once symptoms appear and is a public health concern because it can be transmitted to humans.
Puppies receive a series of core vaccines starting at six to eight weeks of age, with boosters every three to four weeks until sixteen weeks. An initial booster is given one year later, followed by boosters every one to three years depending on the vaccine type and your veterinarian’s recommendation. Rabies vaccination is required by law in most jurisdictions.
Non-Core Vaccines
Non-core vaccines are recommended based on your dog’s risk of exposure. Bordetella bronchiseptica protects against kennel cough and is recommended for dogs that board, attend daycare, visit dog parks, or participate in group training classes. Leptospirosis is a bacterial disease transmitted through wildlife urine and is recommended for dogs that hike, swim in natural water, or live in areas where the disease is prevalent. Canine influenza is recommended for dogs with frequent social exposure. Lyme disease vaccine is recommended in areas where black-legged ticks are common.
Vaccine Safety
Vaccines are very safe, but no medical intervention is entirely risk-free. Mild side effects can include lethargy, soreness at the injection site, and mild fever for twenty-four to forty-eight hours. Serious adverse reactions are rare. The risk of contracting a preventable disease far outweighs the minimal risk of vaccination. If your dog has had a previous vaccine reaction, your veterinarian can design an alternative protocol.
Parasite Prevention
Parasites threaten your dog’s health year-round, even in colder climates. Internal parasites like heartworms, roundworms, hookworms, and whipworms cause significant disease. External parasites like fleas and ticks cause discomfort and transmit diseases.
Heartworm Prevention
Heartworm disease is spread by mosquitoes and is present in all fifty states. The adult worms live in the heart and pulmonary arteries, causing progressive damage to the heart and lungs. Treatment is expensive, painful, and carries risks. Prevention is simple, safe, and inexpensive. Monthly heartworm preventives are available as chewable tablets, topical solutions, and injectable products. The American Heartworm Society recommends year-round prevention and annual testing.
Flea and Tick Control
Fleas cause itching, allergic dermatitis, and transmit tapeworms. Ticks transmit Lyme disease, ehrlichiosis, anaplasmosis, and Rocky Mountain spotted fever. Monthly preventives are available in oral and topical formulations. Products containing isoxazoline compounds like fluralaner and afoxolaner are highly effective against both fleas and ticks. Some combination products also prevent heartworms and intestinal parasites.
Check your dog for ticks after outdoor activities, especially in wooded or grassy areas. Pay close attention to the ears, armpits, groin, and between the toes. Remove ticks promptly with fine-tipped tweezers, grasping as close to the skin as possible and pulling straight out with steady pressure.
Dental Health
Dental disease is the most common health problem in dogs, affecting over 80 percent of dogs by age three. Periodontal disease begins with plaque accumulation on the teeth. If not removed, plaque mineralizes into tartar. Bacteria in tartar cause inflammation of the gums, destruction of the tooth-supporting structures, and eventually tooth loss. Bacteria from the mouth can enter the bloodstream and damage the heart, liver, and kidneys.
Home dental care is the first line of defense. Brushing your dog’s teeth daily with pet-safe toothpaste is the gold standard. Dental chews, water additives, and specially formulated dental diets provide supplemental benefits but do not replace brushing. Annual professional dental cleaning under anesthesia is necessary to remove tartar below the gumline and assess dental health.
Watch for signs of dental disease including bad breath, red or bleeding gums, yellow-brown tartar on the teeth, difficulty eating, pawing at the mouth, and drooling. If you notice any of these signs, schedule a veterinary dental examination.
For optimal health, pair preventive care with good dog nutrition and regular dog exercise to maintain your dog’s overall wellness.
Recognizing Signs of Illness
Early recognition of illness improves outcomes. Dogs cannot tell us when they feel unwell, so we must rely on observation. Changes in behavior are often the first sign that something is wrong.
Take your dog to the veterinarian if you notice any of the following: vomiting or diarrhea lasting more than twenty-four hours, refusal to eat for more than twenty-four hours, lethargy or weakness, coughing or difficulty breathing, limping lasting more than a day, lumps that grow or change, unexplained weight loss, excessive drinking or urination, sudden behavior changes, or seizures.
Emergency Signs
Some situations require immediate veterinary attention. These include difficulty breathing, collapse or unconsciousness, seizures lasting more than two minutes, severe bleeding that does not stop with pressure, suspected toxin ingestion, bloated abdomen with unproductive retching, eye injuries, and heat stroke with excessive panting and collapse. If you are unsure whether a situation is urgent, call your veterinarian or an emergency veterinary clinic for guidance.

Breed-Specific Health Concerns
Some health conditions are more common in certain breeds. Large and giant breeds are predisposed to hip dysplasia, elbow dysplasia, bloat, and certain heart conditions. Brachycephalic breeds like Bulldogs, Pugs, and French Bulldogs are prone to breathing difficulties, eye ulcers, and skin fold infections. Small breeds often struggle with dental disease, patellar luxation, and tracheal collapse. Herding breeds have higher rates of certain genetic eye diseases.
Researching breed-specific health risks helps you monitor for early signs. If you have a breed predisposed to certain conditions, your veterinarian can recommend targeted screening and preventive measures.
FAQ
How often should my dog see the veterinarian?
Healthy adult dogs need an annual wellness exam. Puppies need multiple visits for vaccinations and growth monitoring. Senior dogs over age seven should be seen every six months. Any concerning symptoms warrant immediate attention regardless of the schedule.
What vaccines does my dog really need?
All dogs need core vaccines: distemper, adenovirus, parvovirus, and rabies. Non-core vaccines depend on your dog’s lifestyle. Your veterinarian can recommend appropriate non-core vaccines based on your dog’s specific risk factors.
Does my dog need heartworm prevention in winter?
Yes. The American Heartworm Society recommends year-round prevention in all fifty states. Mosquitoes can survive indoors and during warm winter spells, and prevention is far safer and cheaper than treatment.
Why does my dog have bad breath?
Persistent bad breath is usually caused by dental disease. Schedule a veterinary dental examination. Other possible causes include kidney disease, diabetes, and sinus infections. Do not ignore chronic bad breath.
At what age is my dog considered a senior?
Small breeds are typically senior around age eleven to twelve. Medium breeds around age ten. Large breeds around age eight. Giant breeds around age six. Senior wellness care including blood work and urinalysis should begin at these ages.
