It is necessary for dogs to be vaccinated with the eight vaccines. The eight vaccines protect against eight common infectious diseases: canine distemper virus, canine microvirus, canine parainfluenza virus, canine coronavirus, canine adenovirus type I, canine adenovirus type II, canine leptospirosis type I and canine leptospirosis type II. All eight of these diseases are clinically dangerous and have a high mortality rate. Of these, Leptospira canis type I and Leptospira canis type II are zoonotic, so it is in the interests of both humans and dogs to give your dog the Octavirus vaccine.
