Unfortunately, this isn’t true. It’s important to have your pet vaccinated every year to maintain their immunity against disease. So, for the rest of their life, your puppy will need annual boosters against illnesses such as:
- Canine distemper virus, a virus with no known cure.
- Infectious canine hepatitis, which usually affects dogs less than two years old.
- Leptospirosis, a bacterial disease spread via infected urine or contaminated water.
- Canine parvovirus, a highly contagious viral disease that’s especially severe in puppies.
- Canine parainfluenza, which is a cause of ‘kennel cough’.
