IN ALL THE YEARS I HAVE DOGS I GIVE THEM A PARVO SHOT AT 4-6 WEEKS , AND A 7 IN 1 AT 12 WEEKS, THE ONLY OTHER SHOT THEY GET AFTER THAT IS IF THEY DONT WORK .
spot on you only need to jab them when they are pups to give them that extra cover until their immune system is up and working have only ever jabbed when they were pups and have never had any probs the only person that will tell you it is nessecery is the vet
