Your Dog’s Preventive Care Schedule: What Your Vet Does and Why It Matters
The preventive care schedule recommended by veterinarians exists because most of the conditions that cause dogs significant suffering and expensive emergency treatment are preventable or manageable when caught early. The heartworm infection that costs $1,000 to $3,000 to treat and seriously harms the heart and lungs over years of infection costs $35 per year to prevent. The dental disease that requires $800 to $2,500 in dental cleanings under anesthesia and causes chronic pain when it’s established is managed far more easily with consistent home dental care and earlier professional cleaning. Preventive care is not primarily about extending your dog’s life on paper. It’s about extending the portion of life that is healthy, pain-free, and fully active.
The Core Vaccine Schedule
Core vaccines — those recommended for all dogs regardless of lifestyle — protect against distemper, parvovirus, adenovirus (hepatitis), and rabies. The puppy series typically begins at 6 to 8 weeks, with boosters every 3 to 4 weeks until 16 weeks of age. Rabies is administered once between 12 and 16 weeks, with a booster at one year and then every one to three years depending on local regulations and vaccine type. Non-core vaccines — Bordetella (kennel cough), leptospirosis, Lyme disease, canine influenza — are recommended based on individual lifestyle risk factors. A dog that visits dog parks, boarding facilities, or heavily wooded areas has different vaccine needs than one that lives largely at home and takes private walks.
Parasite Prevention
Heartworm prevention is a monthly medication that prevents heartworm larvae from developing into adult worms. It must be given consistently every month in most climates — heartworm has been diagnosed in all 50 states and the lifecycle allows infection year-round in warm climates and during warm months in temperate ones. A dog must test negative for heartworm before starting prevention — giving prevention to a dog with an active heartworm infection can cause a dangerous reaction. Flea and tick prevention varies in form — topical, oral, or collar — and in spectrum of coverage. Discuss with your veterinarian which product is appropriate for your dog’s size, age, and the specific parasites in your geographic area.
Annual Wellness Exams: What Is Actually Being Evaluated
The annual wellness exam is not primarily about vaccines and parasite testing. It is a systematic physical evaluation that dogs cannot provide themselves — dogs mask pain and early disease signs well enough that owners frequently do not notice problems that a trained examiner detects on physical examination. The veterinarian checks eyes, ears, oral cavity (dental disease is endemic in adult dogs), heart and lung function via auscultation, abdominal organs by palpation, lymph nodes, skin and coat condition, joint mobility, and body condition score. Routine bloodwork run annually in middle-aged and senior dogs catches organ function changes before they become emergencies. The exam is the investment in early detection that consistently produces better outcomes and lower treatment costs than emergency treatment of advanced disease.
