Pet Health Checkup Timing and Examination Items

ImmunityQ&AMeongsiljang Veterinary Advisory Board

For healthy adult dogs and cats, we recommend annual health checkups, while those aged seven and older should have them every six months. Here’s a summary of age-based checkup intervals and the basic and detailed examination items included.

When Should You Get a Pet Health Checkup?

Pet health check-ups are a preventive medical practice that involves regular blood, imaging, and urine tests to detect diseases early. Pets have an instinctive tendency to hide their pain, so by the time owners notice something is wrong, the illness has often progressed significantly. Regular health check-ups are the most reliable way to catch these hidden conditions early and ensure timely treatment.

Why Are Regular Health Checkups Important?

Because pets age more quickly than humans, regular health monitoring is even more important. An annual check-up may not be enough to fully assess the rapidly changing health status of your pet. Diseases that can be managed with dietary adjustments or simple medications if detected early may require surgery or become difficult to treat if found later. According to veterinary guidelines, regular check-ups and early intervention can help detect conditions such as kidney disease, diabetes, thyroid disorders, and heart disease before symptoms appear, improving treatment success rates. Health check-ups are not just for when your pet is sick—they are about checking while your pet is still healthy.

Age-Based Health Checkup Intervals

The recommended frequency of health check-ups varies depending on your pet’s age and overall health status.

Age	Check-up Frequency	Primary Purpose
Under 1 year (Infancy)	As needed, aligned with vaccination schedule	Screening for congenital conditions, vaccinations, and growth monitoring
1–6 years (Adulthood)	Once a year	Assessment of baseline health, weight management, and oral care
7–10 years (Middle age)	Every six months	Early detection of organ function changes, joint and cardiac evaluation
11 years and older (Senior)	Every six months, plus comprehensive diagnostics	Monitoring chronic conditions and early detection of tumors

Examination Items Included in Basic Health Checkups

These are the standard components of a health checkup at a veterinary clinic, and most clinics include them in their basic packages.

Physical Examination: We measure weight, body temperature, heart rate, and respiratory rate, and perform a hands-on exam to check for any abnormalities.

Blood Test (Serum Chemistry): We assess the function of major organs by evaluating liver and kidney values, blood sugar, electrolytes, and more.

Complete Blood Count (CBC): We check for anemia, infection, and inflammation by examining red blood cell, white blood cell, and platelet levels.

Urinalysis: This test helps evaluate kidney function and detect urinary tract infections or diabetes.

Fecal Examination: We check for intestinal parasite infections.

For Pets Aged 7 and Older, Basic Exams Alone May Not Be Enough

As pets age, many chronic conditions don’t show obvious early symptoms, making them easy to miss with basic exams alone. Subtle signs of pain or illness can be hard for owners to notice, and diseases may already be progressing even when no outward symptoms are visible. This is why regular check-ups for early detection become even more important. For senior pets, adding advanced tests like ultrasounds, chest X-rays, and blood pressure measurements to routine exams can help identify hidden changes earlier. Consult your veterinarian to create a check-up plan tailored to your pet’s age and health status.

Additional Items for Detailed Health Checkups

In addition to basic tests, these are advanced diagnostic options that may be recommended based on your pet’s age and breed.

Abdominal Ultrasound: Evaluates structural abnormalities in abdominal organs such as the liver, kidneys, spleen, and bladder.

Thoracic Radiography (X-ray): Assesses heart size, lung condition, and bronchial abnormalities.

Echocardiogram (Cardiac Ultrasound): Provides a detailed evaluation of heart valve disease and myocardial conditions.

Thyroid Hormone Testing: Particularly important for middle-aged and older cats.

Blood Pressure Measurement: Screens for hypertension associated with kidney or heart disease.

Prepare Like This Before Your Health Checkup

Preparing in advance can help ensure more accurate results during your pet’s checkup.

Fasting: If blood tests are included, fasting may be required beforehand. Please confirm the required fasting duration and whether water is allowed when making your appointment.

Urine and Fecal Samples: Bringing a sample of your pet’s morning urine or stool in a clean container can speed up the testing process.

Daily Observations: Note any noticeable changes in appetite, water intake, bowel movements, or behavior to share with the veterinarian.

Current Medications and Supplements: Providing a list of any medications or supplements your pet is currently taking will greatly assist the veterinarian.

Certain Breeds Require Additional Testing

Certain breeds are genetically predisposed to specific conditions, which may require additional testing. For example, in breeds at high risk for hypertrophic cardiomyopathy (HCM), such as Maine Coons and Ragdolls, it is recommended to perform genetic testing along with annual cardiac ultrasound evaluations—especially if the cat is intended for breeding or is at particularly high risk—to detect early signs of the disease. Because susceptibility to congenital and hereditary conditions varies by breed, basic wellness exams alone may not be sufficient for some. Therefore, during regular check-ups, be sure to ask your veterinarian about breed-specific conditions to watch for and the appropriate screening tests. Knowing your cat’s breed characteristics in advance helps you detect and prepare for vulnerable conditions earlier.

Frequently Asked Questions

How much does a routine health checkup usually cost?

The specific tests included can vary from one clinic to another. Many veterinary hospitals offer separate packages for basic and comprehensive exams, so it’s a good idea to ask about exactly what’s included and the associated costs when you make your appointment.

Should cats also undergo health checkups?

Yes, cats absolutely need regular check-ups too. Cats tend to hide signs of illness, making routine veterinary exams even more important. Starting at around seven years of age, when cats enter their mature adult stage, age-related changes in organ function can begin. It’s a good idea to consult with your veterinarian about any additional tests that may be needed and to tailor the exam accordingly.

If the checkup results are normal, can I skip the next checkup?

In general, it’s fine to wait until the next scheduled check-up. However, if you notice any unusual symptoms in the meantime—such as a decreased appetite, changes in weight, repeated vomiting or diarrhea, or sudden changes in water intake—please visit the clinic right away.

Can my pet get a health checkup without anesthesia?

Basic health checkups are performed without anesthesia. Physical examinations, blood tests, and urinalysis all do not require anesthesia. However, anesthesia may be necessary for dental scaling or biopsies.

Do puppies and kittens also need their own separate health checkups?

For pets under one year of age, you can have a basic health check-up during each visit for scheduled vaccinations. This is important because it allows for the early detection of congenital issues such as heart disease or patellar luxation.
