If there is no history of vaccinations, I would have the Distemper / Parvo / Adenovirus vaccine administered (this is a yearly vaccine), the bordetella vaccine and his Rabies vaccination. I recommend heartgard for heartworm prevention along with yearly heartworm testing. Heartgard is a monthly chewable tablet give to prevent heartworm disease. If you live in an area where fleas and ticks are prevalent, I would also suggest a flea / tick preventative such as Nexgard or Bravecto. I hope this helps! Please let me know if you have any questions or concerns. I am also available via consultation if needed.
