Core Vaccines

Distemper Vaccine

The distemper vaccine is a crucial core vaccination for dogs. Distemper is a highly contagious viral disease that affects various body systems and can be potentially fatal. The vaccine provides protection against this serious illness by stimulating the dog’s immune system to produce antibodies that fight off the virus. It is important to note that distemper not only affects dogs but also other animals like raccoons, foxes, and skunks, so it is vital to keep your dog vaccinated to prevent exposure.

Adenovirus Vaccine

The adenovirus vaccine protects dogs against two different strains of the virus: adenovirus type 1 and adenovirus type 2. Adenovirus type 1 causes infectious canine hepatitis, which can lead to severe liver disease and even death. Adenovirus type 2 is responsible for respiratory infections in dogs. Both strains of the virus can be prevented by vaccination, reducing the risk of these potentially serious illnesses.

Parvovirus Vaccine

Parvovirus is a highly contagious viral disease that affects the intestinal tract of dogs, leading to severe vomiting, diarrhea, and dehydration. Puppies are particularly vulnerable to parvovirus, and the disease can be fatal if not treated promptly. Vaccination against parvovirus is crucial to protect your dog from this devastating illness. The vaccine stimulates the immune system to produce antibodies that prevent infection or reduce the severity of the disease if exposure occurs.

Rabies Vaccine

The rabies vaccine is not only essential for the health of your dog but also required by law in most jurisdictions. Rabies is a deadly viral disease that affects the central nervous system, and it can be transmitted to humans and other animals through the bite of an infected animal. Vaccinating your dog against rabies not only protects them from this fatal disease but also helps prevent its spread to other animals and humans. It is important to keep your dog’s rabies vaccination up to date and follow the recommended schedule for booster shots.

Non-Core Vaccines

Leptospirosis Vaccine

Leptospirosis is a bacterial infection that can cause severe kidney and liver damage in dogs. It is transmitted through contact with infected urine, water, or soil. Dogs who spend a lot of time outdoors or live in areas with a high incidence of leptospirosis are at a higher risk. The leptospirosis vaccine is not considered a core vaccine but may be recommended based on your dog’s lifestyle and location. Consult your veterinarian to determine whether your dog should receive this vaccination.

Bordetella Vaccine

Bordetella, also known as kennel cough, is a highly contagious respiratory infection that can spread easily in environments where dogs are in close proximity, such as boarding facilities, dog parks, or training classes. The bordetella vaccine helps protect against this common infection and is often required by these facilities before admission. If your dog frequently interacts with other dogs or is at a higher risk of exposure, it is advisable to vaccinate them against kennel cough.

Lyme Disease Vaccine

Lyme disease is a tick-borne illness caused by the bacterium Borrelia burgdorferi. It can cause joint swelling, lameness, fever, and fatigue in dogs. If left untreated, Lyme disease can lead to more severe complications. The Lyme disease vaccine is available for dogs living in areas where ticks carrying the bacteria are prevalent. If you live in or frequently visit regions with a high incidence of Lyme disease, it is worth considering vaccinating your dog against this infection. However, tick prevention methods should still be used, as the vaccine does not provide complete protection against all strains of Lyme disease.

Canine Influenza Vaccine

Canine influenza, or dog flu, is a respiratory infection that affects dogs. It is highly contagious and can spread quickly in environments where dogs congregate, such as kennels or dog shows. The canine influenza vaccine can help reduce the risk of your dog contracting this illness. While it is not considered a core vaccine, it may be recommended if your dog has a higher likelihood of exposure, such as being in contact with other dogs in high-risk areas or participating in activities where close contact with other dogs is common.

What Vaccinations Are Essential For Dogs?

Puppy Vaccinations

First Set of Vaccinations

When you bring a new puppy home, it is essential to start their vaccination schedule as soon as possible. The first set of vaccinations typically includes the distemper, adenovirus, parvovirus, and sometimes the parainfluenza vaccines. These vaccines are usually administered together in a combination vaccine known as the DA2PP or DHPP vaccine. This initial set of vaccinations helps provide the puppy with protection against common and potentially dangerous diseases.

Second Set of Vaccinations

The second set of vaccinations is usually given when the puppy is around 3-4 weeks older than the initial vaccination. This set often includes booster shots of the core vaccines given in the first set. By administering booster shots, the puppy’s immune system is strengthened and ensures optimal protection against these diseases. Consult your veterinarian to determine the appropriate timing for the second set of vaccinations based on your puppy’s age and overall health.

Third Set of Vaccinations

The third set of vaccinations typically completes the initial core vaccination series for puppies. Around 3-4 weeks after the second set of vaccinations, the puppy will receive the final booster shots for the core vaccines, ensuring long-lasting immunity against these diseases. Keep in mind that depending on your veterinarian’s recommendations and your puppy’s lifestyle, additional non-core vaccines may also be administered during this time. It is important to follow the recommended vaccination schedule to ensure your puppy’s optimal health and protection.

Vaccination Schedule

Initial Vaccinations

The initial vaccinations for puppies are typically given in a series of sets to provide proper immunity against diseases. The exact schedule may vary depending on the vaccine manufacturer and your veterinarian’s recommendations. Usually, the first set of vaccinations is given when the puppy is around 6-8 weeks old, followed by the second and third sets at 10-12 weeks and 14-16 weeks, respectively. These initial vaccinations are crucial in establishing a strong immune system foundation for your puppy.

Booster Shots

After the initial vaccination series, dogs require booster shots to maintain their immunity. Booster shots are typically given annually or every three years, depending on the vaccine type and your veterinarian’s recommendations. Booster shots help strengthen the immune response and reinforce the dog’s protection against the targeted diseases. Regular booster shots are necessary to ensure your dog’s ongoing health and protection from infectious diseases.

Annual Revaccinations

In addition to booster shots, annual revaccinations for core vaccines are often recommended. These revaccinations help maintain optimal immunity levels against diseases like distemper, adenovirus, parvovirus, and rabies. Non-core vaccines may also require annual revaccinations, depending on the individual vaccine’s duration of immunity. Regular revaccinations are crucial to ensure your dog’s long-term health and protection against preventable illnesses.
