The core vaccines (Rabies, Distemper, Parvo, Adenovirus2, Parainfluenza) are normally given once every three years after they are over a year old. The necessity for other vaccines (leptospirosis, Bordetella, etc.) will depend on the dog's environment and are given more frequently. To help answer this question and give you more information, I've put a link to the vaccination guidelines below. https://www.petcoach.co/article/vaccination-schedules-for-dogs-and-puppies/ I recommend the vaccines be given as directed by your veterinarian to ensure the vaccine is given appropriately and to ensure adequate support is available in case of a vaccine reaction. I hope that helps and all is well with Suzie.
