Dog Vaccines: What Every Owner Needs to Know

Vaccines are the quickest way to protect your dog from deadly diseases. Skipping them isn’t an option if you want a long, happy life for your furry friend. Below you’ll find the basics, the must‑have shots, and a timeline that works for most pups.

Core Vaccines for All Dogs

Veterinarians agree on four core vaccines that every dog should get, regardless of breed or lifestyle. These are the vaccines that protect against the biggest threats:

• Rabies: Required by law in most places. One dose gives protection for a year or three years, depending on the product.
• Distemper: A virus that attacks the respiratory, gastrointestinal, and nervous systems. It’s highly contagious in shelters and dog parks.
• Parvovirus: Causes severe vomiting and diarrhea. Young puppies are especially vulnerable.
• Adenovirus (CAV‑2): Prevents infectious hepatitis and contributes to protection against respiratory disease.

These shots are usually given as a combination vaccine (DHPP) to reduce the number of injections and vet visits.

Vaccination Schedule and What to Expect

Most puppies start their vaccine series at 6‑8 weeks old. Here’s a typical timeline:

1. 6‑8 weeks: First DHPP dose.
2. 10‑12 weeks: Second DHPP dose.
3. 14‑16 weeks: Third DHPP dose and first rabies shot (if required).
4. 1 year: Booster for DHPP and rabies.
5. Every 1‑3 years: Boosters based on your vet’s recommendation and local laws.

If your dog is an adult that never got vaccinated, the vet will likely give a rapid series with closer intervals, then space out the boosters later.

Side effects are usually mild—maybe a low‑grade fever, a little soreness at the injection site, or a brief loss of appetite. If your dog vomits, has a prolonged fever, or seems unusually lethargic, call the clinic right away.

Beyond core shots, there are optional vaccines for dogs that travel, hunt, or spend a lot of time outdoors. These include Bordetella (kennel cough), Leptospirosis, Lyme disease, and Canine Influenza. Talk to your vet about which extras fit your dog’s lifestyle.

Keeping records is a habit that pays off. Most vets provide a vaccine card, and many online pet portals let you store the info digitally. Good paperwork means you won’t miss a booster, and it’s handy when boarding or traveling.

In short, vaccines are a small price to pay for a disease‑free life. Stick to the schedule, watch for any reactions, and stay in touch with your vet. Your dog will thank you with wagging tails for years to come.
