Annual Health Screening: What Your Vet Checks and Why It Matters

Your pet ages roughly 5–7 years for every human year. That means skipping one annual exam is like you skipping a doctor's visit for half a decade. In that time, a treatable condition can become a terminal one.

Studies show that annual health screening detects significant problems in 1 in 5 apparently healthy pets. Kidney disease, diabetes, thyroid disorders, and early-stage cancers often show no outward symptoms until they're advanced.

"The exams I value most are the ones where the owner says 'she's perfectly fine.' That's when I find the lump they haven't noticed, the heart murmur they can't hear, or the blood work that reveals early kidney decline. Early detection changes outcomes." — Dr. Sarah Chen, DVM

For a complete schedule of how often your pet should visit the vet, see our vet visit frequency guide.

A thorough physical exam covers every body system in just 10–15 minutes:

• Weight and body condition — compared to previous visits to track trends
• Eyes — clarity, pupil response, signs of cataracts, discharge, or retinal changes
• Ears — infection, mites, wax buildup, polyps
• Mouth and teeth — dental disease, gum recession, masses, broken teeth
• Heart and lungs — auscultation with a stethoscope for murmurs, arrhythmias, lung sounds
• Abdomen — palpation for organ size, masses, pain, fluid
• Skin and coat — parasites, lumps, hair loss, skin infections, allergies
• Lymph nodes — swelling can indicate infection or cancer
• Joints and muscles — range of motion, pain, swelling, muscle wasting
• Neurological quick-check — reflexes, gait, balance

Your vet can detect problems through touch, sound, and observation that no home check can replicate. A heart murmur, an enlarged liver, or a tiny skin mass may be completely invisible to you but obvious to trained hands.

Your vet may recommend baseline blood work from age 1–2, with more comprehensive panels as your pet ages.

Complete Blood Count (CBC)

• Red blood cells — anaemia, dehydration
• White blood cells — infection, inflammation, leukaemia
• Platelets — clotting ability

Biochemistry Panel

• Kidney values (BUN, creatinine, SDMA) — kidney disease is the leading cause of death in older cats
• Liver enzymes (ALT, ALP) — liver disease, toxin exposure, metabolic issues
• Blood glucose — diabetes screening
• Electrolytes — sodium, potassium, calcium balance
• Total protein and albumin — nutritional status, liver/kidney function

Additional Tests

• Thyroid (T4) — hyperthyroidism (common in older cats), hypothyroidism (dogs)
• Urinalysis — kidney function, diabetes, urinary infections, crystals
• Heartworm/tick-borne disease test — annual for dogs in endemic areas

Understanding your pet's baseline values makes it easier to spot changes over time — this is why vets recommend starting blood work before problems appear, not after. See our pain recognition guide for what to watch between appointments.

Puppies & Kittens (First Year)

• Vaccination series and boosters
• Faecal testing for intestinal parasites
• Growth assessment and nutrition counselling
• Spay/neuter timing discussion
• Behavioural assessment

Adults (1–7 Years)

• Annual vaccinations or titre testing
• Dental assessment (professional cleaning may be recommended)
• Weight management counselling if needed
• Baseline blood work from age 3–5

Seniors (7+ Years)

• Bi-annual exams recommended (every 6 months)
• Comprehensive blood panel and urinalysis annually
• Blood pressure measurement
• Thyroid screening (especially cats)
• Joint/mobility assessment
• Cognitive function check (especially dogs — see our CCD guide)

A little preparation makes the appointment more productive:

• Write down your questions — it's easy to forget them in the consulting room
• Note any changes — eating habits, energy levels, lumps, drinking more, toilet changes
• Bring a fresh stool sample if requested (in a sealed bag or container)
• Know their current diet — brand, amount, treats, supplements
• List all medications and supplements — including flea/worm products
• Bring previous records if you've changed vet practices
• Keep your pet calm — pheromone spray in the carrier for cats, a familiar blanket, and treats for positive association

Don't downplay concerns because you think they're minor. "She's drinking a bit more" could be the first sign of diabetes or kidney disease. "He's slowed down a little" could be arthritis or heart disease. Your vet would rather investigate and find nothing than miss something early.
