Well then, there is your answer... the 1-year is safe.
Im not being a smart arse... I work at a vet, have for MANY years and only letting other know a few facts. :shrug:
Just because its a 3yr shot doesnt mean they are getting "more" then a 1yr shot...... all shots given are 1cc ... and there are certain places EACH vaccine should be given now to keep track of reactions.
any vaccine can develop into a small mass... even on dogs. not all turn into cancer. They do monitor cats more than dogs but they have also come along way with the feline vaccines because of that reason. This is also why they have spit vaccines up and started to give them in specific areas.
Point is... if you really feel your pet doesnt need even the "yearly" shots... dont give them
But Rabies is LAW
Many vets push shots on owners to make a quick buck.. That’s their money maker…. And vaccinating your pet yearly is really doing more harm than good! For dogs the only thing that should be done yearly is Lepto because its Titer only lasts maybe 6 months to a year. (but not all dogs need this) Just as not all dogs need to be vaccinated for Kennel cough or even Lyme.
