Did you know, Immunity is a concept that is applied to our pets as well and is not simply related to humans! Immunity is an umbrella concept that does play a pivotal role in our day-to-day lives.

The definition of Immunity is the ability of an organism to resist a particular infection or toxin by the action of specific antibodies or sensitized white blood cells. In simpler terms, Immunity is the ability of your body (or your pet’s body) to fight back an Infection, to kill and remove the disease-causing microorganisms. There are little army or fighter cells called the White Blood Cells, which act as the fighters against any infection. These little fighters are responsible for killing, eating (phagocytosis), and discarding most of the disease-causing microorganisms that invade your body. It is a complex biological system that has the ability to recognize whatever belongs to the self-body and to reject what is foreign to the body (non-self), for example, microbes.


Immunity is the body’s natural way to fight and resist infection. It can either be naturally present inside your pet due to genetic factors etc or due to the mother’s Milk or it could be acquired by vaccination or fighting infection. Let’s see what exactly is Innate vs. Acquired Immunity.


Innate Immunity is the type of Immunity that is present right from birth.

It is the inborn resistance mechanism against disease-causing microorganisms and infections that an individual possesses right from birth due to their genetic makeup.


This type of Immunity is, however, adapted or acquired by an organism after birth via vaccines or exposure to microorganisms.


Immunity and immune response vary a lot from one individual to another, species to species. It’s a perfect amalgamation of genetic factors and environmental factors.

The immune response thus owes a major of its chunk to environmental factors apart from genetic factors. Let’s understand various factors one by one.

Factors influencing Immune Response are :


Age plays the most important role in the Immunity of pets. Mostly young and old, the extreme ends of the life cycle are particularly vulnerable to infections due to hampered Immunity. Let’s see how.

In young puppies or kittens, there is something called Maternal antibodies, which are present in the Milk of the mother. These antibodies are essential and are meant to protect kittens and puppies from diseases and infections. Thus it’s important to give the puppies and kittens their mother’s milk when they are young. Adequate maternal antibodies are thus essential to prevent severe or chronic illness or death. Mother’s Milk has immunoglobulins (which help in immunity building) which help your pets immensely.

It’s also very important to note here that puppies younger than 45 days should not be weaned as it might cause puppies to have less Immunity. Also, as a vigilant pet parent, it is advisable not to buy puppies and kittens younger than the prescribed age since it’s always better to have pets with good Immunity and health as this will affect your puppies and kitties in the long run.

The younger population of pets like kittens and puppies are at greater risk of infection as they are still building their Immunity up. Certain infections such as Parvo Virus Infection in puppies or Feline Leukemia Virus in kittens are some of the diseases which affect the younger population as compared to the older ones, and this is because the younger animals are more susceptible to infections.

Thus, age here is a crucial factor.

This is why we vaccinate our puppies and kittens from the 6th to 8th week onwards against various organisms like Parvo Virus, Leptospira, Adeno Virus, etc., in puppies through the 9 in 1 Vaccine.

While in cats, we vaccinate them to build up Immunity against Calicivirus, Feline Leukemia Virus (FeLV), etc.

These vaccinations are initially given at 6th– 7th week onwards, followed by booster doses for the same and then followed by Anti Rabies Vaccine, which again builds up Immunity against the deadly Rabies Virus. This vaccination schedule must be followed as it helps to prevent life-threatening conditions since it helps to build up the Immunity of the animal.

Annual vaccination is thus done to keep the Immunity at a stable level and help your pets to lead a healthy, happy life.


Nutrition plays a vital role in Immunity. Gut health plays a crucial role in Immunity, as does what your pets eat. A diet rich in optimum levels of minerals, vitamins, fibers, carbohydrates, essential fatty acids, and proteins is important to give your pets all nutrients essential to build up a strong body and Stronger Immunity.

Here are some nutrients which are important for the development of a normal immune response –

Vitamins like: Vitamin A, Vitamin D, Vitamin C, and B vitamins (Vitamin B complex)

Polyunsaturated fatty acids,

Minerals like: Calcium, Copper, Selenium Chromium, Zinc, etc

Many of these nutrients act as antioxidants which have the ability to protect the immune cells from oxidative damage and help in the building of a strong immune system.


Stress is one of the factors which hampers the Immunity of your pets.

Sudden stress will lead to the release of adrenaline that will suppress the immune response. Long-term stress causes the release of cortisol, which is also immunosuppressive at high levels.

Any kind of physical or emotional stress affects your pets, for example – a sudden change of atmosphere and environment, severe weather changes (extremely high temperature, extremely low temperature), traveling, excessive handling, trauma, illness, pregnancy, boarding, etc.


If there is poor sanitation or poor Management practices, it might take a toll on the Immunity of your pets.

For example, in the case of kennel cough, your puppy may have been subjected to poor hygiene or an unhealthy atmosphere, such as a dog boarding facility without adequate vaccination or protection against the same.


Exercise plays a huge role in building Immunity in your pets. A series of regular exercises enhances immune response. However, it’s important to note here that over-exertion or Strenuous exercise results in oxidative damage to the cells and will have a backfire effect, increasing the susceptibility to infections. Anything in excess is harmful. Thus, regular walks, and regular exercise are important.
Also, never exercise your pets immediately before or after food as again it will have harmful effects on your pet’s system. Exercise should be moderated and done in proper quantities.
Immunity plays a crucial role in protecting your pet throughout its life. There are many microbes in the environment, and always remember the golden rule – ‘Prevention is better than cure.’
Vaccinate your furry friends routinely, provide them with good nutritious food and supplements, proper exercise, a good environment, happy atmosphere for the overall health and protection of your pet.

The importance of Immunity is immense, as it is important for health and resistance!
