Vaccinating your puppy is one of the most important steps you can take to ensure their lifelong health and well-being. At North Rocks Veterinary Hospital, we routinely vaccinate against five serious infectious agents to protect puppies from potentially fatal diseases. Additionally, we vaccinate against Leptospirosis, a disease that has become increasingly significant. Here, we’ll explain the diseases we vaccinate against and why vaccination is crucial for your furry friend.
PUPPY VACCINATION
WHY WE VACCINATE PUPPIES AT NORTH ROCKS VETERINARY HOSPITAL

1. PARVOVIRUS

Parvovirus is a highly contagious and often fatal disease that is unfortunately still prevalent in our area. It spreads through contact with infected animals or their droppings, and the virus can survive in the environment for long periods. Even puppies that stay indoors or avoid other dogs are at risk because the virus can be transmitted via shoes, clothing, or a dog’s hair or feet.
Symptoms
Severe inflammation of the intestines, vomiting, loss of appetite, profuse foul-smelling bloody diarrhea, weight loss, abdominal pain, and often death despite intensive treatment.
2. DISTEMPER

Distemper is a viral disease that affects the respiratory, gastrointestinal, and nervous systems. It is spread through airborne droplets from bodily fluids like saliva or urine of infected dogs.
Symptoms
Runny eyes and nose, coughing, vomiting, diarrhea, and, in advanced cases, seizures and other neurological signs.
Vaccination programs have made distemper less common, but occasional outbreaks still occur. Keeping your puppy vaccinated ensures they are protected.
3. INFECTIOUS CANINE HEPATITIS

This is a highly contagious disease that primarily targets the liver but can also affect the kidneys, eyes, and respiratory system. It is spread through contact with infected urine, feces, or saliva.
Symptoms
Fever, loss of appetite, vomiting, diarrhea, and abdominal pain.
4. KENNEL COUGH
Infectious Canine Tracheobronchitis & Bordetella Bronchiseptica

Kennel Cough is a highly contagious respiratory disease spread through coughing, sneezing, or nose-to-nose contact.
Symptoms
A dry, hacking cough, retching, fatigue, loss of appetite, and in severe cases, progression to pneumonia.
Although most dogs recover fully, the infection can linger for weeks, and affected dogs can remain contagious for up to 14 weeks. Vaccination significantly reduces the risk and severity of this condition.
5. LEPTOSPIROSIS

Leptospirosis is a bacterial disease that affects both dogs and humans. It is spread through contact with water, soil, or food contaminated with urine from infected animals, such as rodents or wildlife. The disease thrives in wet or humid conditions, making it a growing concern in many areas.
Symptoms
Fever, vomiting, diarrhea, lethargy, muscle pain, jaundice (yellowing of the skin or eyes), increased thirst, and kidney or liver failure in severe cases.
Leptospirosis can cause severe illness and is potentially fatal. Vaccination not only protects your dog but also reduces the risk of transmission to humans. Given the zoonotic nature of the disease, vaccinating against Leptospirosis is a critical step in safeguarding your family and your pet.
VACCINATION SCHEDULE AT NRVH

We follow a structured vaccination schedule to provide optimal protection for your puppy:
- 1st Vaccination: 8 - 11 weeks
- 2nd Vaccination: 12 - 15 weeks
- 3rd Vaccination: 16+ weeks
- Annual Booster: Given 12 months after the initial series
A new vaccine is available that protects against parvovirus, hepatitis, and distemper for three years. However, vaccines for kennel cough and leptospirosis still require annual boosters.

The Importance of Early Socialisation
We recommend puppies be socialised between 3 and 16 weeks of age. Our vaccination regime ensures protection during this critical period, allowing your puppy to safely interact with other dogs, animals, and people. Enrolling your puppy in our Puppy Preschool is a great way to combine early socialisation with expert guidance.
