Core Vaccinations


Distemper is a highly contagious viral disease that can affect multiple organs in puppies, including the respiratory, gastrointestinal, and nervous systems. It spreads through contact with infected animals or contaminated objects. Symptoms of distemper include fever, coughing, vomiting, diarrhea, and neurological issues. Vaccination against distemper is crucial to protect your puppy from this potentially devastating disease.


Parvovirus is another highly contagious viral disease that affects the intestinal tract of dogs. It can cause severe vomiting, diarrhea, dehydration, and in some cases, even death. Parvovirus can survive in the environment for an extended period, making it easy for puppies to come into contact with the virus. Vaccinating your puppy against parvovirus can significantly reduce the risk of infection and ensure their health and well-being.


Hepatitis in dogs is caused by the canine adenovirus type 1 (CAV-1). It primarily affects the liver and can cause fever, abdominal pain, vomiting, and jaundice. Hepatitis is transmitted through contact with infected urine, saliva, or feces. Vaccination provides protection against this potentially serious disease and is an essential part of your puppy’s overall health care.

Rabies is a viral disease that affects the central nervous system and is usually transmitted through the bite or scratch of an infected animal. It is a fatal disease that can affect both animals and humans. Vaccination against rabies is not only important for your puppy’s health but is also required by law in many areas. It is typically administered when the puppy is around 16 weeks old and requires regular booster shots to maintain immunity.

Non-Core Vaccinations

Bordetella Bronchiseptica

Bordetella bronchiseptica is a bacterium that causes a respiratory infection commonly known as kennel cough. It is highly contagious and can spread rapidly in environments where dogs are in close proximity, such as boarding facilities or dog parks. While not a core vaccine, it may be recommended if your puppy is frequently exposed to other dogs.


Leptospirosis is a bacterial infection that can affect multiple organs in dogs, including the liver and kidneys. It is transmitted through contact with infected urine or contaminated water sources. Leptospirosis can also be passed to humans, making it a zoonotic disease. Depending on your puppy’s lifestyle and exposure, your veterinarian may recommend vaccinating against leptospirosis.

Lyme Disease

Lyme disease is caused by a bacterium called Borrelia burgdorferi and is transmitted through the bite of infected ticks. It can cause joint pain, lameness, fever, lethargy, and in severe cases, kidney damage. Vaccination against Lyme disease may be recommended if you live in an area where ticks are prevalent and your puppy is at a higher risk of exposure.

Canine Influenza

Canine influenza, or dog flu, is a contagious respiratory infection caused by two distinct strains of the influenza virus. Symptoms include coughing, sneezing, fever, nasal discharge, and decreased appetite. If your puppy is frequently in contact with other dogs, especially in areas where canine influenza has been reported, your veterinarian may recommend vaccination.

Vaccination Schedule

Here is the schedule of vaccines according to their age:

6-8 Weeks

Your puppy’s vaccination journey typically begins around 6-8 weeks of age. At this stage, they will receive their first round of vaccinations, including the core vaccines. These initial vaccinations help kickstart their immune system and protect them against common infectious diseases.

10-12 Weeks

Around 10-12 weeks of age, your puppy will receive their next set of vaccinations, including booster shots for the core vaccines. These boosters help ensure that your puppy’s immunity is strong and built up to protect against potential diseases.

14-16 Weeks

At 14-16 weeks of age, your puppy will undergo their final round of core vaccinations, which include booster shots to reinforce their immunity. By completing the core vaccinations, your puppy will have a strong foundation of protection against the most common and dangerous diseases.

1 Year

After completing the initial vaccination series, it is essential to schedule a vaccine appointment when your puppy reaches one year of age. During this visit, your veterinarian will conduct a thorough examination and administer booster shots to maintain your puppy’s immunity.

Booster Shots

Booster shots are given at regular intervals throughout your puppy’s life to maintain their immunity levels. The frequency of booster shots depends on the specific vaccine and your veterinarian’s recommendations. Staying up-to-date with booster shots is crucial to ensure that your puppy remains protected against infectious diseases.

Vaccine Precautions


Some puppies may have allergies or sensitivities to certain vaccine components. It is important to inform your veterinarian of any known allergies or adverse reactions to previous vaccinations. They can determine if any modifications or alternative vaccines are necessary to avoid an allergic reaction in your puppy.

Sick or Immunocompromised Puppies

If your puppy is sick or immunocompromised, such as having a weakened immune system, it is crucial to consult with your veterinarian before administering any vaccines. In some cases, it may be necessary to postpone or modify the vaccination schedule to ensure the safety and well-being of your puppy.

Side Effects of Vaccination

Localized Reactions

It is not uncommon for puppies to experience localized reactions at the injection site. These reactions may include slight swelling, redness, or tenderness. In most cases, these reactions are mild and resolve on their own without any intervention. However, if you notice any concerning or persistent reactions, it is essential to consult with your veterinarian.

Mild Systemic Reactions

Some puppies may experience mild systemic reactions after vaccination, such as a mild fever, decreased appetite, or lethargy. These reactions are typically short-lived and resolve without intervention. However, if you notice any severe or prolonged systemic reactions, it is important to notify your veterinarian.

Severe Systemic Reactions

Although rare, severe systemic reactions can occur after vaccination. These reactions may include difficulty breathing, hives, swelling, vomiting, diarrhea, or collapse. If you observe any severe reactions, it is crucial to seek immediate veterinary care.

Choosing a Veterinarian

Experience with Canine Vaccinations

When it comes to choosing a veterinarian for your puppy, it is essential to consider their experience and expertise in administering canine vaccinations. Look for a veterinarian who stays up-to-date with the latest vaccination protocols and has a deep understanding of the specific needs of puppies.

Communication and Trust

Building a strong relationship with your veterinarian is crucial for your puppy’s overall health and well-being. Look for a veterinarian who communicates effectively, listens to your concerns, and provides clear explanations about vaccinations and any potential risks or side effects. Trust and open communication with your veterinarian will help ensure that your puppy receives the best possible care.

Vaccine Records

Importance of Keeping Records

Keeping accurate and up-to-date vaccine records is crucial for many reasons. Vaccine records provide a detailed history of your puppy’s vaccinations and can serve as proof of vaccination when necessary. They also help your veterinarian determine the appropriate vaccinations for your puppy based on their age, lifestyle, and medical history. Additionally, vaccine records are often required when enrolling your puppy in training classes, daycare, or boarding facilities.

Digital or Physical Copies

There are various ways to keep vaccine records, including digital copies or physical copies. Digital records can be stored on your computer or smartphone for easy access and can be shared with others if needed. Physical copies can be organized in a file folder or binder and kept in a safe place. Whichever method you choose, ensure that you store your puppy’s vaccine records in a secure and easily accessible location.

Risk of Not Vaccinating

Disease Outbreaks

One significant risk of not vaccinating your puppy is the potential for disease outbreaks. Without proper immunization, your puppy is more susceptible to infectious diseases that can spread rapidly within the dog population. This not only puts your puppy at risk but also poses a threat to other dogs they come into contact with.

Legal Requirements

Vaccination against rabies is often required by law in many areas. Failure to comply with these regulations can result in fines or other legal consequences. It is essential to familiarize yourself with local vaccination requirements and ensure that your puppy receives the necessary vaccinations within the specified timelines.

Exclusion from Pet Facilities

Many pet facilities, such as boarding facilities, grooming salons, or dog parks, have specific vaccination requirements to ensure the health and safety of all animals. If your puppy is not properly vaccinated, they may be restricted or excluded from accessing these facilities, limiting their socialization opportunities and overall well-being.

Socialization and Vaccination

Balancing Socialization and Immunity Building

Socialization is a critical aspect of a puppy’s development, helping them grow into well-adjusted and confident dogs. However, socialization should be balanced with the need to build immunity through vaccinations. It is important to choose controlled and safe socialization opportunities while ensuring that your puppy receives the necessary vaccinations to protect them from potential diseases. Consult with your veterinarian to strike the right balance between socialization and immunity building for your puppy.

Benefits and Limitations of Vaccinations

Protection against Infectious Diseases

The primary benefit of vaccinations is the protection they provide against various infectious diseases. By vaccinating your puppy, you significantly reduce their risk of contracting and spreading these diseases. Vaccinations are a vital tool in preventing outbreaks and maintaining overall canine health.

Lifespan of Vaccinations

It is important to note that vaccines have different durations of protection. Some vaccines may provide immunity for several years, while others may require more frequent booster shots to maintain effectiveness. Understanding the lifespan of vaccinations is crucial in ensuring that your puppy remains adequately protected throughout their life. Consult with your veterinarian to determine the recommended vaccination schedule for your specific puppy.


In conclusion, vaccinations play a vital role in protecting your new puppy from potentially life-threatening diseases and ensuring their overall health and well-being. By following a comprehensive vaccination schedule, taking necessary precautions, choosing the right veterinarian, keeping accurate vaccine records, and understanding the risks and benefits of vaccinations, you can give your puppy the best possible start in life.
