Hello, Dr. Soheyl from Noble Vets . Here are some tips and information regarding vaccinations in pets. We do require vaccinating our pets at certain ages. Once we get a new kitten or puppy, we need to vaccinate them at the age of 6 or 8 weeks, and then we follow it with another booster in a month's time. Usually, vaccinations need to be repeated once a year to keep the antibodies boosted in the blood. Vaccinating your pet has many advantages, like protecting them against diseases that are mostly deadly. By ensuring you vaccinate your pets once a year, you will prevent them from catching these diseases, and you will keep their immune system boosted.
