Your Dog's Annual Wellness Exam: What Vets Actually Check and Why

The Nose-to-Tail Physical Exam: What Your Vet Is Actually Doing

When the vet says they're doing a "physical," they mean a systematic evaluation of virtually every body system. Most owners are surprised by how much ground gets covered in a single visit.

• Eyes and ears: The vet looks for discharge, redness, cloudiness, or signs of infection. Ear infections are among the most common canine conditions and are often caught before they become painful.
• Mouth and teeth: Dental disease affects the majority of dogs over three years old. The vet checks for tartar buildup, gum inflammation, cracked teeth, and oral masses. Poor dental health has documented links to heart, kidney, and liver issues.
• Lymph nodes: Enlarged nodes can signal infection or, less commonly, cancer. Vets palpate nodes under the jaw, behind the knees, and in the groin area.
• Heart and lungs: Using a stethoscope, the vet listens for heart murmurs, irregular rhythms, and abnormal lung sounds. Early-detected murmurs can be monitored and managed before causing clinical symptoms.
• Abdomen: Gentle palpation helps the vet assess organ size, detect masses, and identify pain responses that might indicate gastrointestinal, urinary, or reproductive issues.
• Skin and coat: The vet examines for parasites, skin lesions, lumps, or coat changes that may reflect allergies, hormonal imbalances, or nutritional gaps.
• Musculoskeletal system: Gait, joint range of motion, and muscle mass are evaluated — particularly important for identifying early arthritis in middle-aged and older dogs.
• Weight and body condition: The vet assigns a body condition score (BCS), a standardized scale used to assess whether your dog is underweight, at an ideal weight, or overweight. Obesity is one of the most common preventable health problems in pet dogs.

Understanding your dog's body language can also help you flag subtle discomfort at home before your next exam.

Vaccines, Parasite Prevention, and Diagnostics

Beyond the physical, the wellness visit is when your vet reviews and updates preventive care protocols.

Vaccine Review

Your vet will check your dog's vaccination history and recommend boosters based on current guidelines from veterinary professional organizations. Core vaccines protect against rabies and the DHPP group. Lifestyle-based vaccines — Bordetella (kennel cough), Lyme disease, leptospirosis, and canine influenza — are discussed based on where you live and how often your dog encounters other dogs or wildlife.

Parasite Screening and Prevention

A fecal exam checks for intestinal parasites like roundworms, hookworms, whipworms, and Giardia. Many dogs harbor parasites without visible symptoms. The vet will also review your current heartworm prevention and flea and tick control methods, and may recommend a heartworm antigen test if due.

Optional Diagnostics

Depending on your dog's age and history, the vet may recommend bloodwork, a urinalysis, or thyroid testing. These aren't always mandatory at every visit but become increasingly valuable as dogs age. See our guide to senior dog care to understand how screening needs evolve after age seven.

How to Make the Visit Count: Preparation and Follow-Through

The exam is only as useful as the information you and your vet exchange. A few preparation steps dramatically increase the value of each visit.

Before You Go

Note any changes in your dog's eating, drinking, energy level, bathroom habits, or behavior since the last visit. Even small shifts — drinking more water, sleeping longer, hesitating on stairs — can be clinically meaningful. Collect a fresh stool sample the morning of the appointment.

During the Appointment

Don't save questions for the end. Raise concerns as they come up during the exam, since the vet can often demonstrate what they're finding in real time. Ask what any recommended test would actually tell you and what happens if you skip it.

After the Visit

Request a written visit summary or ask how to access your records through the clinic's patient portal. If your vet recommends follow-up care — a dental cleaning, a recheck in three months, a referral — write it down and schedule it before leaving. Preventive care only works if recommendations are actually followed through.

If cost is a concern, it may be worth reviewing how pet insurance for dogs handles wellness visits and diagnostics before your next appointment. And if your household includes a cat, our companion article on your cat's annual vet visit walks through how feline exams differ.
