Unfortunately, it is not always about how much exposure she has to other dogs... it is more about what dogs have had exposure to her 'land'... strays, wanderers off leash etc... I give my dogs a 7 way shot annually that I get at my local coop or TSC.. soloject 7.... they are about $7 a piece and its all done...just let your vet know by retaining the box end with the batch number etc for her records... hope this helps..
