Welcoming a new puppy into your life is an exciting and chaotic time, one that is filled with adorable tail wags and zoomies. But amid the cuddles and chew toys, there’s one thing every new pet parent needs to take seriously: vaccinations.

At Safford Veterinary Services in Plano, IL, we help local pet owners stay on top of their puppy’s vaccination schedule so their four-legged bestie gets the protection he needs during those critical early months. Whether little Fido is your first puppy or your fifth, understanding when and why to vaccinate is key to preventing dangerous—and often avoidable—illnesses.

Here’s everything you need to know to give your pup the healthiest possible start.

Why Vaccines Matter: A Lifesaving Head Start

Vaccinations work by training your pup’s immune system to recognize and fight off specific viruses or bacteria. Puppies are especially vulnerable during their early weeks because their immune systems are still developing. While mom’s antibodies offer some protection at birth, this defense isn’t enough in and of itself. It leaves a gap that vaccines fill.

Fun fact: The first dog vaccine ever developed was for rabies. That was back in 1885! Today, we vaccinate dogs against multiple life-threatening diseases, many of which are still active in the U.S.

Understanding Core vs. Non-Core Vaccines

At our Oswego, IL veterinary clinic, we group dog vaccines into two main categories:

Core Vaccines (Recommended for All Dogs)

These protect against diseases that are widespread, highly contagious, and potentially fatal:

• Distemper
  
• Parvovirus
  
• Adenovirus (canine hepatitis)
  
• Rabies
  

Non-Core Vaccines (Based on Risk)

These are given depending on your pup’s lifestyle, environment, or exposure risks:

• Leptospirosis
  
• Bordetella bronchiseptica (kennel cough)
  
• Lyme disease
  
• Canine influenza
  

We may recommend these additional vaccines based on risk factors. If your dog will be around other dogs (boarding, grooming, dog parks) or is going to travel with you, he may need the Bordetella vaccine. 

Puppy Vaccination Schedule by Age

Your pup will need a series of shots spaced out over a few months, followed by boosters to maintain immunity. Here’s a breakdown of a typical puppy vaccination schedule by age:

6–8 Weeks

• DHPP #1 (Distemper, Hepatitis, Parvovirus, Parainfluenza)
  Often done with a fecal test and deworming and wellness exam
  

Note: Some breeders start vaccines at 6 weeks. If your pup comes home earlier than 8 weeks, check to see if he’s already had a dose. Bring any records to your first vet visit.

10–12 Weeks

• DHPP #2
  
• Bordetella (optional but highly recommended for social pups)
  
• Leptospirosis #1 (if recommended)
  
• Deworming and weight check
  

14–16 Weeks

• DHPP #3
  
• Leptospirosis #2
  
• Rabies (required by law in most areas, including IL)
  
• Wellness exam and growth tracking
  

16–18 Weeks

• Canine Influenza (for social or high-risk dogs)
  
• Lyme #1 (if needed)
  

Pro Tip: Keep your pup out of high-risk environments like dog parks or daycare until he’s finished his core vaccine series. This will usually be around 16 weeks of age.

What About Boosters?

Once your puppy completes his initial vaccine series, he’ll need booster shots at 1 year of age,
then every 1–3 years, depending on the vaccine and lifestyle risks

Our veterinarians at Safford Veterinary Services tailor booster schedules based on your dog’s health, breed, and environment.

Common Puppy Vaccines Explained

Here’s a closer look at the most important vaccines for your new furry buddy:

DHPP (Combo Vaccine)

This combination vaccine protects against four major diseases:

• Distemper: A virus that attacks the respiratory, GI, and nervous systems.
  
• Hepatitis (Adenovirus-2): Affects the liver, eyes, and kidneys.
  
• Parvovirus: A highly contagious virus that causes severe vomiting and diarrhea. It is often fatal without treatment.
  
• Parainfluenza: A respiratory virus that contributes to kennel cough.
  

Rabies

The rabies vaccine is often legally required. Rabies is extremely deadly and is transmissible to humans. It’s almost always fatal once symptoms appear.

Leptospirosis

A bacterial infection spread through water contaminated by animal urine. It can lead to kidney or liver failure—and can infect humans too.

Bordetella (Kennel Cough)

This vaccine helps prevent a nasty hacking cough that spreads in grooming salons, dog parks, kennels, and daycares.

Canine Influenza

The dog flu spreads like wildfire in group settings. Vaccination is often required by boarding facilities and grooming salons.

Lyme Disease

Transmitted through tick bites, Lyme can cause chronic joint pain and kidney issues. It’s most relevant in wooded or tick-prone areas.

How Much Do Puppy Vaccines Cost?

The total cost varies by region and clinic, but many veterinary clinics offer puppy wellness packages that include:

• Exams
  
• Core vaccines
  
• Deworming
  
• Fecal checks
  

At Safford Veterinary Services, we can create a customized, affordable vaccine plan tailored to your pup’s needs.

Can Puppies Have Side Effects?

Mild side effects are rare but they do happen. Typical reactions may include:

• Soreness at the injection site
  
• Mild fever or sleepiness
  
• Occasional decreased appetite for 24–48 hours
  

Severe reactions (vomiting, swelling, difficulty breathing) are extremely rare. If you notice any unusual symptoms, call your vet right away.

FAQ: Puppy Vaccination Schedule

Can I skip any vaccines?

You really shouldn’t. Skipping core vaccines leaves your puppy vulnerable to fatal diseases. Some non-core vaccines are optional, but still beneficial. Always consult your veterinarian.

How soon can I take my puppy out in public?

Wait until at least one week after the final DHPP vaccine. This is typically around 16 weeks. Early socialization is very important to little Fido’s development, but his safety comes first.

Can I vaccinate my puppy at home?

Vaccinations should only be given by a licensed vet. Improper administration, storage issues, and missed boosters can put your pup at risk.

What if I miss a booster?

Call us right away. We may need to restart the series, depending on how much time has passed.
