Vaccinating a puppy is one of the crucial steps in assuring they will have a healthy and happy puppyhood. The who, what, why, when, where, and how of vaccinations are complicated, and may vary from puppy to puppy. Always consult with your veterinarian to determine which vaccines are appropriate for your puppy. To better understand vaccines, it is important to understand how the puppy is protected from disease the first few weeks of its life.
Protection from the mother (maternal antibodies):
A newborn puppy is not naturally immune to diseases. However, it does have some antibody protection which is derived from its mother's blood via the placenta. The next level of immunity is from antibodies derived from the first milk, called colostrum, which is only produced from the time of birth and continues for the first 36-48 hours. After the first 36-48 hours have passed the puppy does not continue to receive antibodies through its mother's milk, so it is very important to make sure they are nursing well right after born. All antibodies derived from the mother, either via her blood or colostrum are called maternal antibodies. It must be noted that the puppy will only receive antibodies against diseases for which the mother had been recently vaccinated against or exposed to. As an example, a mother that had NOT been vaccinated against or exposed to parvovirus, would not have any antibodies against parvovirus to pass along to her puppies. The puppies then would be susceptible to developing a parvovirus infection. We vaccinate all of our dogs for Parvo so that is not an issue to worry about with our puppies, it was just an example.
Window of susceptibility:
The age at which puppies can effectively be immunized (protected) is proportional to the amount of antibodies the puppy received from its mother. High levels of maternal antibodies present in the puppies' bloodstream will block the effectiveness of a vaccine. When the maternal antibodies drop to a low enough level in the puppy, immunization by a commercial vaccine will work.
The antibodies from the mother generally circulate in the newborn's blood for a number of weeks. There is a period of time from several days to several weeks in which the maternal antibodies are too low to provide protection against the disease, but too high to allow a vaccine to work. This period is called the window of susceptibility. This is the time when despite being vaccinated, a puppy or kitten can still contract the disease.
When should puppies be vaccinated?
The length and timing of the window of susceptibility is different in every litter, and even between individuals in a litter. A study of a cross section of different puppies showed that the age at which they were able to respond to a vaccine and develop protection (become immunized) covered a wide period of time. At six weeks of age, 25% of the puppies could be immunized. At 9 weeks of age, 40% of the puppies were able to respond to the vaccine. The number increased to 60% by 16 weeks of age, and by 18 weeks, 95% of the puppies were protected by the vaccine.
Almost all researchers agree that for puppies and kittens, we need to give at least three combination vaccinations and repeat these at one year of age.
| Consult with your veterinarian to determine which vaccinations your puppy should receive, and how often. |
Some breeders prefer to vaccinate puppies with a combination vaccine at six weeks of age initially, with boosters given every three weeks until the puppy is about sixteen weeks of age. Feeling that this schedule will help protect the widest range of dogs. Realizing that with that protocol, they will be vaccinating some dogs that are not capable of responding, and will be revaccinating some dogs that have already responded and developed a protection. But without doing an individual test on each puppy, it is impossible to determine when the puppy's immune system will be best able to respond. Realizing that in the face of an infection, due to the window of susceptibility, some litters will contract a disease (e.g., parvo) despite being vaccinated. By using quality vaccines and an aggressive vaccination protocol, they can make this window of susceptibility as small as possible. This vaccination protocol may not be right for every puppy. Puppies that are not exposed to other dogs and have a very small chance of coming in contact with parvovirus, may not need to be vaccinated as frequently. At the same time, some 'high risk' puppies may need a more intense and aggressive vaccination program. It is best to work with your veterinarian on a vaccination protocol that is best for your individual puppy or kennel, taking into consideration your individual situation.
Against which diseases should puppies be vaccinated?
The AVMA Council on Biologic and Therapeutic Agents' Report on Cat and Dog Vaccines has recommneded that the core vaccines for dogs include distemper, canine adenovirus-2 (hepatitis and respiratory disease), canine parvovirus-2 and rabies.
Noncore vaccines include leptospirosis, coronavirus, canine parainfluenza and Bordetella bronchiseptica (both are causes of "kennel cough", and Borrelia burgdorferi (causes Lyme Disease). Consult with your veterinarian to select the proper vaccines for your puppy.
We begin vaccines when our puppies are six weeks of age and always recommend to our adopting families that the puppies continue to get boosters along w/a Rabies vaccine when their puppy is old enough. It is also very important to continue to de-worm your puppy, even though they have been de-wormed here. When our puppies go to their new homes they will have received a Neopar Vaccine ( protects against Parvo,) a Bordetella Vaccine (protects against Kennel Cough,) and a 5-N-1 Vaccine ( protects against canine parvovirus CPV, adenovirus type 1 hepatitis and type 2 respiratory disease, parainfluenza, and distemper. Protects against all known strains of CPV, including CPV-2c. Also protects against 2 types of adenovirus that cause hepatitis and respiratory disease in dogs.) They will have also received several rounds of de-wormers that protect against various worms common amongst animals/puppies. When the puppies go home they come with a vaccination history that has the names, dates, brand, and serial numbers of all vaccines and de-wormers they have received so that their new vet can see what they have had and continue a vaccination schedule as the puppy grows. Vaccines are very important, if you want your puppy to live a long and healthy life please be sure to keep your pets up to date on their shots.
