Depends on lots of factors - If you don't vaccinate the dog - its life expectancy can be as short as few weeks if it catches Parvo. It can be short if you let it run loose to be hit by a car, or let it suffer some other fate ... like if you chain it in your yard to be poisoned or stolen. If you do everything right and the dog has good genetics - you feed it well, and give it vet care when needed - then you could hope to get 10-15 years out of this cross of breed.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
