Rabies: when you get the shot here, at the vet, THEY are the ones who issue the tag. So you can't just "get" one when you are here.

The certificate will be sufficient until your dogs need another vaccine. It is the law here, they need to be current on a rabies shot. Since they just got their first one, that will be good for ONE YEAR. You must get the dog in to the vet prior to the one year for the next shot. The next one is good for THREE years.

I LOVE your idea to go to a local vet and get the scoop!

If the apartment never HAD a flea problem, they won't have needed to treat it. So no worries if they tell you they didn't do it.

Yes the topical treatment once per month should do it for the fleas. And the once per month heart worm pill will cover you on that bit.
