Preventive Care Without the Upsell: What Your Dog Actually Needs
Vaccines, parasite control, teeth and the yearly check-up: what the guidelines recommend, how often, and where the evidence is thinner than the sales pitch.

Most of what a vet does for a healthy dog is prevention. It is also where owners are most often unsure what is necessary and what is extra. This section sets out what the main veterinary guidelines recommend, and says plainly where the evidence runs out.
While there is real value in the routine care below, more isn’t always better. The global vaccination guidelines say so directly: “Vaccines should not be given needlessly” (Squires et al., WSAVA Vaccination Guidelines Group, J Small Anim Pract 2024).
2. The yearly check-up
The World Small Animal Veterinary Association (WSAVA) guidelines encourage vets to talk about “the value of regular health checks (usually annual, sometimes more often) as opposed to speaking of “vaccination consultations.””
That distinction matters, because the yearly visit isn’t only about injections. The guidelines say “The annual health check is much more than just a vaccination consultation”. It is the vet’s chance to find problems an owner can’t see: dental disease under the gumline, a heart murmur, a lump, a change in weight.
Our note: We haven’t found a study showing that annual check-ups improve outcomes in dogs, so this rests on the WSAVA recommendation.

3. Vaccines
Every dog needs the core vaccines: against distemper, adenovirus and parvovirus everywhere, and against rabies wherever it is present. Other vaccines depend on where you live and how your dog lives.
For adult dogs, WSAVA recommends the core viral vaccines “no more frequently than every 3 years”. Some others, including leptospirosis, need a yearly booster.
Rabies rules are set by law, and they differ by country, province and state.

4. Fleas, ticks and worms
Which parasites matter depends heavily on where you live, and on the season. Your vet knows the local risks.
One class of flea and tick drug, the isoxazolines, carries a US Food and Drug Administration warning about rare neurological reactions. The FDA still “considers products in the isoxazoline class to be safe and effective for dogs and cats” (FDA fact sheet), and advises owners to review their dog’s history with the vet before choosing a product.

Our note: Worming and heartworm advice varies widely between Canada, the US and the UK.
5. Teeth
Gum disease was the most common specific diagnosis in a study of 22,333 UK dogs seen at veterinary practices in 2016, with 12.52% diagnosed in that year (O’Neill et al., BMC Vet Res 2021).
Daily brushing is the best home care. It can’t remove hardened tartar or treat disease under the gumline: that needs a cleaning under anaesthesia. Veterinary dentists advise against cleaning without anaesthesia, which only removes what can be seen.

6. Weight
In the same UK practice records, obesity was diagnosed in 7.07% of dogs in a year, making it the third most common specific diagnosis after gum disease and ear infections (O’Neill et al., BMC Vet Res 2021). As with gum disease, that counts only dogs whose vet recorded it.
Ask your vet to score your dog’s body condition at each check-up, and to show you how to check it at home. → Is My Dog Overweight? Body Condition Scoring at Home
7. How this section works
Every article in this section starts from the main veterinary guidelines: WSAVA’s, which are written for vets worldwide, and, where they differ, the American Animal Hospital Association’s for North America. We say who funds a guideline when it tells us. We don’t recommend products, and we don’t give doses.
Where a recommendation depends on the law or on local disease, the article says so, and will carry a notice for Canada, the US and the UK before it is published.
8. What we could not verify
| Commonly said | What we found |
|---|---|
| “Annual check-ups help dogs live longer” | Not found. WSAVA recommends them; we found no outcome study. |
| “All vaccines are yearly” | No. Core viral vaccines in adults: “no more frequently than every 3 years” (WSAVA). |
| “Flea tablets have been banned” | No. The FDA “considers products in the isoxazoline class to be safe and effective”. |
| “80% of dogs have dental disease by age 2” | Can’t verify. Merck cites a 1997 veterinary dentistry textbook for it, and we couldn’t find the textbook online. |
