Vaccines are an essential part of a puppy’s health care plan. Certain basic immunizations are essential to keep your puppy from getting sick and prevent the spread of disease.
Why Vaccinate Your Puppy?
When puppies are born, their immune systems are not fully developed, so they cannot fight disease. However, during the first two days of a puppy’s life, nursing mothers provide antibody-rich milk called colostrum. These antibodies offer puppies with temporary immunity against illness. While the length of this immunity varies from puppy to pup, it is generally believed that maternal antibodies are gone after about 16 weeks of age.
Enter puppy vaccinations. Vaccines are designed to trigger immune responses and prevent future infection from diseases. All puppies should be administered certain core vaccines which provide immunity against the most dangerous and widespread diseases. Core vaccines are considered essential for puppies in most geographical locations. Depending on your location and your puppy’s environment, non-core vaccines may also be recommended. Talk to your vet about your puppy’s risk of exposure to these diseases.
How They Work
Puppy vaccines are typically first administered at about six to eight weeks old, then repeated every three to four weeks until about four months of age. Some of these vaccines might be given together in one injection that is called a combination vaccine. Avoid bringing your pup to dog parks or otherwise exposing your puppy to unknown animals until all vaccinations have been given. The vaccine injection itself is typically not painful. Some puppies seem to feel a little pinch or sting while others do not react at all.
Your veterinarian will need to do an examination before vaccinating your puppy. Note that vaccines should never be given to a puppy with a fever or illness as the vaccine will not be effective and could actually make the puppy feel worse.
After a vaccine is administered, immunity is not immediate; it takes about five to ten days to become effective. However, puppies that still have maternal antibodies will not develop immunity at all. There is no way to be certain if a puppy still has maternal antibodies, hence the reason for boosters. True immunity is uncertain until about four months of age, or until all puppy boosters are completed. At your puppy’s first veterinary exam, your vet will discuss the schedule of vaccinations and other treatments for your puppy, such as deworming and beginning heartworm prevention. See the chart below for a typical vaccine schedule.
Puppy Vaccine Schedule (Sample):
|Age||Core Vaccines||Non-Core Vaccines*|
|6 to 8 weeks||Distemper, Parvovirus, Adenovirus||Coronavirus, Parainfluenza|
|9 to 11 weeks||Distemper, Parvovirus, Adenovirus||Coronavirus, Leptospirosis, Parainfluenza, Bordetella|
|12 to 14 weeks||Rabies, Distemper, Parvovirus, Adenovirus||Coronavirus, Leptospirosis, Parainfluenza, Lyme, Bordetella|
Recommendation of non-core vaccines depends on your geographical location and your puppy’s environment. Speak to your vet about your puppy’s potential exposure.
A Note on Adult Boosters
Most vaccines require a booster within 1 year after the puppy series. There is a 3- year rabies vaccine. After that, some vaccines will need to be given annually, and others will only have to be given every 3 yrs.
There are some risks associated with vaccinations though relatively uncommon. Vaccine reactions and side effects are typically mild and self-limiting.
Because vaccinations stimulate the immune system, there is a risk of developing an auto-immune disorder. Severe allergic reactions are usually rare but can be fatal if left untreated. If your puppy develops hives, facial swelling, difficulty breathing, vomiting, or bloody diarrhea, contact your vet immediately. Signs may include pain and swelling at the injection site, lethargy or fever. This is very uncommon when you consider the numbers of dogs affected versus all the dogs that are vaccinated. However, auto-immune disorders could be serious and difficult to treat. Illnesses that may occur include blood disorders, neuromuscular issues, and even skin problems.
Despite the potential side effects, most veterinarians and pet experts agree that the benefits outweigh the risk when it comes to puppy vaccines. However, with adult boosters, many vets are embracing protocols that vaccinate less often. Once given annually, many adult vaccinations are now more likely to be recommended every three years.
If you suspect your pet is sick, call your vet immediately. For health-related questions, always consult your veterinarian, as they have examined your pet, know the pet’s health history, and can make the best recommendations for your pet.
