Neglecting to follow a proper dog immunization schedule can expose your pet to various preventable diseases. For example, diseases like parvovirus, which primarily affects puppies, can cause severe vomiting, diarrhea, and even death. Skipping scheduled vaccinations can lead to serious health complications, and in some cases, permanent damage. Without timely vaccinations, your dog may be more susceptible to infections, making recovery more difficult and costly. Delaying or skipping vaccinations could also compromise your dog’s ability to recover from illness due to a weakened immune system. If your dog becomes ill after missing vaccines, treatment options may be more limited or costly. For puppies, immunization is especially critical. Puppies are born with some immunity passed down from their mother’s milk, but this protection starts to fade as they grow. If vaccines are skipped during their crucial early months, they can face a higher risk of developing life-threatening diseases.
