Yes. My vet said that the vaccinations are stronger than they used to be. In fact she told me new studies show that the FVCRP or whatever it's called is strong enough to last up to three years but that yearly vaccinations are still recommended.

The rabies shot is the one that really wipes my guys out and makes them very sore at the site of the shot. Scout will limp for several days afterwards.

Hope Potter feels better soon but if he is still acting this way tomorrow you should probably call your vet and let them know. My vet always says to let them know if they are still feeling bad after 48 hours.
