i was curious on what order of shots i should give my boxer. his last visit to the vet for shots was at 6 months and another visit for heartworm guard test(?) a few months later. he is now 1.5 years and was wondering if any shots should be due for him? i assume his was done for awhile since the vet never sent out any notifications... but just want to make sure im giving my dog the care he needs.
