My 1.5-year-old dog is overdue for her second rabies shot. What now?
You are correct, the first rabies vaccine is only good for one year. After that, depending on where you live, the next rabies vaccine could be good for three years. Some cities/states still require the rabies vaccine to be given every year though so you need to check what the law is in your area. Your vet will know.
All, that being said, with her rabies vaccine being overdue - you need to update it as soon as possible and it may only be marked good for one year because you are overdue. Again, you must check with your vet regarding your local laws.
Regardless, you need to get her rabies vaccine booster as soon as you can.
Hope this answers your question. Best wishes!
