I have a tiny yorkie who is 1.5y/o, 2.5lb. and i I'm not planning on giving him the rabies vaccine. after i read so many bad stories I'm not going to give any of my furbabies rabies vaccines anymore.
my recommendation if Sophie would be mine, i would wait till she is at lest 1y/o before i make a decision.
Also i heard that giving Advantage or any other flea/tick medicine every month is not good. and should only be given if you see fleas on them.
(i personally use revolution flea and tick prevention when i do need it)
Hope this helps. Good luck
