According to the CDC, it’s four doses, preferably in the arm, over a two week period. I think I remember reading about someone who worked at a rescue or rehab that had to get several shots in the shin, around the bite site, but I don’t remember why.

Normally, I would recommend citronella, either the grass or the candles, but I believe it is toxic to dogs.

I believe lavender, catnip and basil are safe, but they’re all mints and may try to take over your garden or yard. They all grow very well in pots though.

You can also try setting a trap. Put out some soapy water. The females are the ones biting you and they need water to lay eggs. They’ll fall in the water and the soap prevents them from escaping. I haven’t actually tried this with mosquitos, just other pests, but I have friends who swear by it.
