Sticking to a dog vaccination schedule is essential as vaccines play a critical role in protecting your pup from organisms that can make them seriously ill. These shield dogs from diseases such as hepatitis, rabies, canine parvovirus, and distemper which can be fatal for them if their bodies are not equipped to ward off the pathogens that cause them.
In this article, we will give you an overview of each vaccine that your dog should receive depending on factors such as medical history, lifestyle, and environment – and the appropriate age your dog should be in to be inoculated with each vaccine.
HOW DO DOG VACCINES WORK?
Vaccines contain antigens that mimic the genetic makeup of a disease-causing organism to condition the immune system to recognize the disease without actually causing it. And when your dog gets exposed to that disease, their immune system would immediately recognize the intruder and fight it off or at least lessen its impact.
Most of these vaccines are initially administered in the first 4 months of your dog’s life. They have 2 classifications: core vaccines and non-core vaccines. Core vaccines are the universal shots given to dogs in consideration of the severity of the disease and the levels of exposure to it. Non-core vaccines are considered optional vaccines, but again, it depends on the area in which you live and the exposure of your dog to these diseases.
WHAT ARE THE CORE VACCINES FOR DOGS?
The parvovirus, or more commonly known as parvo, is a virus that causes severe gastrointestinal illness, and usually infects puppies and young dogs. It is transmitted through direct contact with fecal matter or with a dog infected with the virus. It infects all dogs, but unvaccinated ones are at the most risk of contracting it.
Parvo is highly contagious and can be very life-threatening if your dog gets infected with it, so they need to receive a series of canine parvovirus shots. The first one is given when they’re 6-8 weeks old, the second shot at 10-12 weeks old, and the last one at 14-16 weeks old. A booster shot will be given a year later, and succeedingly, once every 3 years.
The rabies virus mainly attacks the central nervous system and causes headaches, excessive drooling, hallucinations, paralysis, and even death. Your dog can contract the virus through the bite of an infected animal, and symptoms can develop within seconds. Rabies infection may result in death if treatment is not administered early on – but prevention is always better than cure.
The United States and other countries require that dogs receive the rabies vaccine, and it should be administered when your dog is around 14 weeks of age, and an annual shot following that first jab. This also prevents your dog from infecting other animals, including humans.
Canine hepatitis is caused by adenovirus, a highly contagious virus that affects your dog’s kidneys, liver, lungs, spleen, and eyes. It is incurable, but its symptoms can be managed if treatment is immediately given. Though it is not related to the virus that commonly infects humans, both variants are preventable by vaccines. Your dog should receive their hepatitis shot beginning at 10-12 weeks, next at 12-16 months, then once every 1-2 years.
Canine distemper is caused by an airborne virus that attacks your dog’s gastrointestinal, nervous, and respiratory systems. It causes fever, vomiting, coughing, diarrhea, eyes and nose discharge, seizures, paralysis, thickening of footpads, and death.
It is also an incurable disease, and infected dogs can carry the virus for months. The distemper vaccine series must first be administered when your dog is 10-12 weeks old, the second when they’re 16-18 weeks old, then at 12-16 months old. Booster shots should be given once every 1-2 years.
Non-core vaccines, or optional vaccines, include:
- Bordetella and Canine Influenza – both are causes of kennel cough; vaccines are given when puppy is 6-10 weeks old
- Leptospirosis – caused by bacteria found in soil and water; first shot is given at 11-14 weeks, and the second shot at 15-16 weeks
- Lyme Disease – a tick-borne disease; vaccine is first administered when the dog is 11-14 weeks old, then at 15-16 weeks old
Following a dog vaccination schedule and making sure that your pup receives all the needed vaccines would go a long way in protecting them from various deadly diseases. Consult your vet for more information on dog immunization and what schedule would work best for your pet.
