Vaccinations need to be undertaken always by the pet owners and the dogs need to be vaccinated at the appropriate time. This helps to improve the resistance of the animal against some specific diseases causing frequent problems in dogs. The dogs that are orphaned due to the death of the mother have lesser protection in their immune system.
Such animals are to be particularly protected against various diseases.

Vaccination is usually started at the age of five to six weeks and prior to this age, maternal immunity will be helping the animal to have natural disease resistance. It is always better to deworm the animal before the vaccination and this is given emphasis many times. Vaccination against the parvovirus is done at an early age because pups are often affected by parvoviral infections. The booster dose for each vaccine needs to be given at appropriate times and this helps to build up the immune status to an appreciable level. Vaccination is carried out in many countries against rabies disease.

Hence, vaccination against rabies is given more emphasis always. Even rabies tags are fixed on to the dog collar of most of the dogs. Rabies vaccine is given at the age of thirteen to fifteenth weeks of age and is repeated in fifteen months' time. However, this depends on the type of vaccine used. Once in three years, this is repeated.

In dogs that have not received colostrums or dogs at high-risk areas, give measles virus vaccine and killed the parvovirus vaccine before five weeks of age itself. Leptospira serovar vaccine is given at six to eight weeks of age and again at tenth to twelfth weeks and at thirteenth to sixteenth weeks.

Then annually repeat this. Bordetella and Lyme disease vaccinations are only optional ones in the case of dogs. Vaccinations against the canine parainfluenza, canine parvovirus, and canine adenovirus type- two is similar to the schedule maintained with leptospiral serovars.
