Vaccines 101: Keeping Your Dog Protected

Bringing a dog home is one of life's best decisions. Whether you're welcoming a wiggly puppy or a calm adult rescue, one of the most important things you can do for your new family member is stay on top of their vaccinations. It's not the most glamorous topic, but it's one of the simplest ways to keep your dog healthy and happy for years to come.

Why Vaccines Matter

Vaccines protect dogs from serious, sometimes fatal diseases. Without them, dogs are vulnerable to illnesses like parvovirus, distemper, and rabies — diseases that are largely preventable with routine vaccination. Some of these diseases, including rabies, can also spread to humans, making vaccination a matter of community health as much as individual pet care.

What Dogs Receive from SDR

At Saskatoon Dog Rescue, every dog is vaccinated before going home with their new family. Puppies receive at least their first set of core vaccines (DHPP, which covers distemper, hepatitis, parvovirus, and parainfluenza); adult dogs receive at least one full set of core vaccines (DHPP plus rabies), but will most often have received two full sets prior to adoption. Puppies require three sets in total to be fully protected, while adult dogs require two.

Until all sets are complete, dogs are not fully immunized and should be kept away from dog parks and other public places where exposure to unvaccinated dogs is possible.

Your adoption paperwork will outline exactly what your dog has received and when their next vaccines are due, so you'll never have to guess.

Puppy Vaccine Schedules

Puppies need a series of vaccines because their immune systems are still developing. Maternal antibodies passed through their mother's milk can interfere with vaccines early on, which is why multiple rounds are necessary to ensure full protection. Typically, puppies receive their vaccine sets several weeks apart. It's important to follow this schedule closely; falling behind may require starting the series over.

Adult Booster Schedules

Vaccines don't last forever. Adult dogs need boosters to maintain their protection over time. Rabies and DHPP boosters are required either annually or every 1–3 years, depending on the vaccine type and your veterinarian's recommendation. Your vet can help you build a schedule that makes sense for your dog's age, lifestyle, and health history.

Common Vaccine Myths

"My dog stays indoors, so they don't need vaccines." Even indoor dogs can be exposed to disease through contact with other animals, shoes, clothing, or the outdoors. Rabies can also spread to humans, making vaccination important regardless of your dog's lifestyle.

"Vaccines can make my dog sick." Mild side effects like sleepiness or slight soreness at the injection site are normal and temporary. Serious reactions are rare. The risks of skipping vaccines far outweigh the minor discomfort of getting them.

"Once my dog is vaccinated, they're protected forever." Unfortunately, no. Most vaccines require regular boosters to stay effective.

A Note on Cost

Vet costs can add up, but vaccines are one of the most cost-effective investments you can make in your dog's health. Preventing disease is almost always less expensive than treating it. Low-cost vaccine clinics are available in many communities. Don't hesitate to ask your vet about options.

The Bottom Line

Vaccinations are one of the simplest ways to protect your dog's future. Following their vaccine schedule is one of the easiest and most impactful things you can do as a pet owner. If you're unsure where your dog stands, your adoption paperwork is a great starting point, and your vet can fill in the rest.
