I disagree about vacinations, and unless you have evidence (not anectote) to back up you belief, then it is superstition (by definition). I buried 4 fully vacinated dogs at 14 to 15 years old (2 German shepards, and 2 Norweigen elkhounds) a few years back. Feed them meat instead of grain and the immune diseases will be uncommon. Canines are carnivours. And please keep your unvacinated dogs contained so my family and dogs don't catch their diseases! Sorry, but mistreated pets at the hands of do-gooders is a pet peeve of mine (pun intended).
