Why Should My Dog Have Vaccines?

Vaccinating your dog is one of the most effective ways to protect them from potentially life-threatening diseases. Here are some key reasons why dog vaccinations are essential:

1. Prevention of Serious Illnesses – Vaccines help prevent highly contagious diseases like rabies, distemper, and parvovirus.
2. Legal Requirements – In many places, core vaccines (such as rabies) are required by law.
3. Protecting Other Animals – Some diseases can spread between pets, and vaccinations help protect not just your dog but others too.
4. Cost-Effective Care – Treating a preventable disease is often far more expensive than getting your dog vaccinated.
5. Peace of Mind – Knowing that your dog is protected allows you to enjoy more worry-free adventures together.

Core Vaccines for Dogs

Core vaccines are those that are recommended for all dogs, regardless of breed, lifestyle, or location. These vaccines protect against diseases that are either highly contagious, severe, or pose a public health risk.

1. Rabies

• Why it’s important: Rabies is a deadly viral disease that affects the nervous system and is fatal in nearly all cases. It can spread to humans and other animals through bites.
• When to vaccinate: First dose at 12-16 weeks old, with a booster after one year. Additional boosters every 1-3 years, depending on local laws.

2. Canine Distemper

• Why it’s important: Distemper is a highly contagious virus that affects the respiratory, gastrointestinal, and nervous systems.
• When to vaccinate: Typically given as part of the DHPP vaccine starting at 6-8 weeks, with boosters every 3-4 weeks until 16 weeks old. Booster shots are needed every 1-3 years.

3. Parvovirus (CPV)

• Why it’s important: Parvo is a severe and often fatal disease that affects puppies and unvaccinated dogs. It causes vomiting, diarrhea, and dehydration.
• When to vaccinate: Initial vaccination at 6-8 weeks old, then boosters every 3-4 weeks until 16 weeks. Booster shots every 1-3 years.

4. Adenovirus (Hepatitis) Type 1 & 2

• Why it’s important: This vaccine protects against canine hepatitis and respiratory infections.
• When to vaccinate: Included in the DHPP vaccine series at 6-8 weeks, with boosters as needed.

Optional Vaccines & When to Get Them

Optional vaccines, also known as non-core vaccines, are recommended based on a dog’s lifestyle, location, and exposure risks. Here are some common optional vaccines and when they should be considered:

1. Bordetella (Kennel Cough)

• Why it’s important: Helps prevent kennel cough, which is common in dogs that socialize frequently.
• When to vaccinate: Given annually or semi-annually if your dog visits dog parks, boarding facilities, or training classes.

2. Leptospirosis

• Why it’s important: Protects against a bacterial infection that can spread to humans and cause severe liver and kidney issues.
• When to vaccinate: Given yearly, especially for dogs in rural or wet environments.

3. Lyme Disease

• Why it’s important: Protects against a tick-borne disease that can cause joint pain, fever, and kidney damage.
• When to vaccinate: Given yearly, particularly for dogs in tick-infested areas.

4. Canine Influenza (Dog Flu)

• Why it’s important: Protects against highly contagious strains of flu that affect dogs.
• When to vaccinate: Annually for dogs that frequent kennels, dog shows, or doggy daycares.

What Happens If My Dog Isn’t Vaccinated?

Not vaccinating your dog puts them at serious risk. Here’s what could happen:

1. Higher Risk of Disease – Your dog is more likely to contract and spread deadly diseases.
2. Expensive Medical Bills – Treating preventable diseases can cost thousands in vet bills.
3. Legal Issues – Many states require rabies vaccinations, and non-compliance can lead to fines.
4. Potential for Transmission – Some diseases can spread from dogs to humans, increasing health risks for pet owners.

What to Do After Your Dog Gets Vaccinated

After a vaccination, most dogs tolerate the shots well, but here are some aftercare tips:

1. Monitor for Reactions – Mild lethargy and soreness at the injection site are normal. Severe reactions (swelling, vomiting, difficulty breathing) require immediate vet attention.
2. Keep Them Calm – Limit intense exercise for 24-48 hours.
3. Provide Fresh Water and Food – Some dogs may have a reduced appetite for a day.
4. Follow Up on Booster Shots – Mark your calendar for the next required vaccination.
