In a general sense, all animals die from health reasons. A responsible and reputable breeder will do everything he/she can to make sure his/her puppies are free of genetic issues such as hip/elbow dysplasia, cystinuria (a hereditary defect that forms calculi stones in the bladder), and subvalvular aortic stenosis (SAS). But health issues can be brought on by poor diet, being over-weight, un-exercised, over-exercised, ect. Even if you do everything right, sometimes a Newfoundland is going to have a health problem, whether or not it is the breeder's fault, the linage's fault or the owner's fault. In my personal experience, I've seen Newfoundlands die of the health issues I listed above, other health issues, such as cancer's, and of old age. I can not say that every Newfoundland dog has/will die from an underlying health reason, but I can say that most dogs, regardless of the breed will pass away or have to be put down because of an underlying health reason.
