The age that you stop vaccinating your dog is 7 years of age.
By 7 years of age dogs are considered senior dogs and vaccinating a senior dog or a dog nearing the end of it's lifespan could cause more health issues than the vaccination solves.
However some senior dogs and dogs above 7 do still get and may require vaccinations but it depends on the dogs lifestyle and overall health.
Typically, senior pets will receive most vaccines every three years.
Some vaccines with shorter duration of immunity, such as kennel cough, leptospirosis, or Lyme disease vaccines, may be given more frequently (every six to twelve months).
All dogs should be vaccinated for rabies at approximately 14 weeks of age, and then again at one year of age.
Depending on your local regulations, re-vaccination should happen every one to three years.
It's never considered too late to vaccinate your dog.
Vaccines help protect your dog from life-threatening illnesses and the earlier they are vaccinated, the better.
Some pet vaccines require multiple doses to provide the best possible protection, so depending on your pet's age, they may require additional boosters.
Vaccines that are optional for puppies include.
Bordetella. Bordetella bronchiseptica is a bacteria that causes the respiratory disease Bordetella.
Canine parainfluenza virus. Canine parainfluenza virus (CPV) is one of the most common causes of canine cough.
