The Annual Check-up: What the Evidence Can and Can't Say

Expert guidelines recommend a check-up at least yearly, and twice yearly for seniors. We found no trial showing that it helps dogs live longer. What it's for.

Written by thecanineledger

The World Small Animal Veterinary Association’s vaccination guidelines say that “The annual health check is much more than just a vaccination consultation” (Squires et al., WSAVA vaccination guidelines, Journal of Small Animal Practice 2024). The US guidelines for dogs at each life stage go further: seniors “should have at least semiannual exams”, meaning at least every six months (Creevy et al., 2019 AAHA Canine Life Stage Guidelines).

While those recommendations are sensible, we found no trial showing that regular check-ups help dogs live longer or healthier lives. This page explains what the guidelines recommend, what they rest on, and how to get the most out of a visit.

1. What the guidelines recommend

The World Small Animal Veterinary Association (WSAVA). Its vaccination guidelines say that “Individualised patient care requires regular (usually annual) health checks”. They encourage vets to talk about “the value of regular health checks (usually annual, sometimes more often) as opposed to speaking of “vaccination consultations.””

The American Animal Hospital Association (AAHA). Its 2019 life stage guidelines set out visits by age:

Life stageAAHA’s definitionSuggested exams
Young adultEnd of rapid growth until about 3 to 4 yearsSemiannually to annually
Mature adultUntil the last 25% of expected lifespanSemiannually to annually, with yearly baseline tests
SeniorThe last 25% of expected lifespanAt least every six months, with baseline tests

The “minimum database” is AAHA’s term for a set of baseline tests, such as blood and urine tests.

Our note: This table is our summary of AAHA’s stage definitions and exam frequencies.

2. What the recommendations rest on

Mostly expert opinion. The AAHA guidelines say that “Evidence-based support for specific recommendations has been cited whenever possible and appropriate.” But “Other recommendations are based on practical clinical experience and a consensus of expert opinion.”

Screening tests are still being studied. AAHA says “The value of a minimum database for detection of occult disease (the presence of disease in the apparently healthy patient) continues to be explored in both human and veterinary healthcare fields.”

Disclosure. The AAHA guidelines are “supported by a generous educational grant” from seven companies. They include animal drug makers, a pet food maker, a veterinary laboratory company and a veterinary credit company.

Our note: We searched for a study comparing dogs with and without regular check-ups and found none.

3. What a check-up can find

Hidden disease in older dogs. In one small study of 101 dogs older than 7, screening before an anaesthetic made 30 new diagnoses. The author concluded that “sub-clinical disease could be present in nearly 30 % of these patients” (Joubert, Journal of the South African Veterinary Association 2007, abstract). The commonest were tumours, chronic kidney disease and Cushing’s disease.

But finding disease isn’t the same as helping. That study didn’t follow the dogs to see whether early diagnosis changed their outcome.

Weight. AAHA cites a study of Labrador Retrievers finding that dogs kept at ideal weight “live an average of 15% longer.” A check-up is a chance to track weight and body condition over time.

Other things a check-up covers. AAHA’s list for each stage includes behaviour, nutrition, parasite control, vaccination, dental health, reproduction and breed-specific conditions.

Our note: AAHA’s Labrador figure comes from a 2002 study of 48 Labradors (Kealy et al., Journal of the American Veterinary Medical Association 2002, abstract). We could read only the abstract. In the study, one dog in each pair was “fed 25% less food than its pair-mate” for life. The abstract says the restricted dogs had a significantly longer median life span, but it gives no 15% figure. It doesn’t say who funded the study. The first author’s listed affiliation is a pet food company’s research department.

4. Why visits get skipped

AAHA notes that practices struggle when owners don’t understand “the need for and value of routine examinations”, when recommendations are unclear, and when the cost is unpredictable.

What helps. Ask for a written plan with costs. Ask which parts of the visit matter most for your dog’s age and breed, and which can wait.

5. Getting the most out of a check-up

Before the visit, note any changes you’ve seen:

  • Drinking, eating, weight, or toilet habits
  • Energy, stiffness, or reluctance to walk or jump
  • Coughing, breathing, or sleep
  • Lumps, bad breath, or skin changes
  • Behaviour, including confusion or anxiety

At the visit, ask:

  • Is my dog’s weight and body condition where it should be?
  • Does my dog’s age or breed mean we should check anything specific?
  • Which vaccines and parasite treatments are needed this year, and why?
  • When should I come back, and what would make you want to see my dog sooner?

Our note: This checklist is ours, built from the areas the guidelines list. If you notice a change, don’t wait for the yearly visit.

6. What we could not verify

Commonly saidWhat we found
“Annual check-ups help dogs live longer”Not shown. Guidelines recommend them; we found no outcome study.
“A check-up is just for vaccines”No. WSAVA calls it “much more than just a vaccination consultation”.
“Senior dogs need two check-ups a year”That’s AAHA’s advice, based mainly on expert opinion.
“Routine blood tests catch disease early”Sometimes. One small study found new disease in nearly 30% of older dogs, but didn’t track outcomes.
“Every dog needs the same check-up”No. Both guidelines say care should fit the dog’s age, breed and lifestyle.
