like corgi, i do distemper and parvo then redo at 1 yr, titers thereafter...
rabies at 6 months (though in honesty i do try to hold off till 8 months if lisencing dates work out) and then again repeat in 1 yr and every 3 yrs after that as required by law.
personally i dont like combos of any kind for toy/small breeds or breeds known to be sensitive...
lepto isnt nessicary in our area and is the most common vaccine to cause severe allercig reactions
bordatella, corona and adeno virus arnt realy nessicary unless your dogs go to daycare/dog parks or socilize with other dogs outside their immediate "family" as there transmitted by other dogs...
i follow an absolute MINIMUM vaccination schedual because both chis and cresties are hihgly rpone to serious vaccine reactions.
