There are many diseases that are fatal to dogs. Fortunately, we have the ability to prevent many of these by the use of very effective vaccines. For dogs they cover Distemper, Hepatitis, Parvovirus and Kennel Cough. We now use 3 year vaccines to protect against most nasties but kennel cough is still required annually. We also recommend an annual heartworm injection so that you dont have to remember to administer monthly treatments. For cats we recommend an F4 vaccine as it protects against the 4 key nasty feline viruses.
